During the period when Song Biao was inspecting the Northeast, it had been snowing and the wind was relatively strong. His original plan was to take a look at the test flight of the prototype test aircraft of the latest model J-7 turbofan fighter when he inspected the Shenyang Aircraft Company. , because the weather conditions have not been very good, under Chen Qicai's suggestion, the plan was finally canceled.
The trip to inspect the Tonghua Missile Base could no longer be delayed. Even though it was still snowing heavily that day, Song Biao, accompanied by Chen Qicai, went to the Shenyang Aircraft Company to inspect, while Crown Prince Yuhua went north to inspect the Harbin Institute of Technology.
This year's Northeast is indeed much colder than in previous years. The lowest daytime and nighttime temperatures in February have broken records in the past thirty years. In mid-March, it was still snowing heavily.
The heavy snow started to fall again last night, and it didn't show any sign of stopping until after nine o'clock in the morning. The convoy of the imperial family slowly set off from the headquarters of the Shenyang Military Region and drove all the way north to the chessboard where the Shenyang Aircraft Company is located. In Shanxi District, a total of 45,000 acres of land from Xinjiaji to Puhe Town belongs to Shenyang Company. Northeast Aviation Industry Research Institute is located in the Tuanshanzi area south of Shenyang Aircraft Company. Shenyang Aircraft Research Institute and Shenyang Aircraft Research Institute are also located next to each other.
Shenfei is a joint-stock private enterprise listed on the China United Stock Exchange, while Northeast Aviation Industry Research Institute is a national scientific research institution. Before 1935, Northeast Aviation Industry Research Institute was affiliated to the Central Academy of Sciences, and socialized reforms were implemented at the Central Academy of Sciences. Later, the Northeast Aviation Industry Research Institute was changed to be affiliated to the Central Scientific Research Commission, which was the newly established China Science and Technology Commission.
The China Science and Technology Commission is directly affiliated with the Cabinet Ministry of Science, Technology and Industry and is a deputy ministerial-level organization. The full-ministerial level establishment previously enjoyed by the Central Academy of Sciences has been abolished, including the original Central Institute of Nuclear Physics, the Central Institute of Aeronautics and Astronautics, and the Central Computer Research Institute. Central Machinery Research Institute, Central Institute of Materials Industry, Central Institute of Geology, Central Aviation Research Institute, Beijing Aviation Industry Research Institute, Northeast Aviation Industry Research Institute, Northeast Electronic Science Research Institute, Shanghai Electronic Science Research Institute, Beijing Semiconductor Industry Research Institute , Northeast Shipbuilding Industry Research Institute, Northeast Automotive Industry Research Institute, Northeast Metallurgical Industry Research Institute, North China Metallurgical Industry Research Institute, Northwest Industrial Research Institute, Northeast Chemical Industry Research Institute and other 122 research institutes nationwide have separated from local and Central Academy of Sciences , directly affiliated to the China Science and Technology Commission, and some other scientific research institutions are directly merged into the provincial national universities.
Through this series of reforms, the Central Academy of Sciences was completely separated from the original government agency system and became a social institution independent of government operations. It is run by the Chinese Science Association, and the main source of funding for the Chinese Science Association is the sponsorship of the royal family.
These national research institutes are different from private institutions. They are mainly engaged in the research of basic theories and basic industrial processes. They also accept sponsorship from enterprises, collaborate with enterprises to research new technologies and new process technologies, and provide theoretical and technical support to enterprises.
In modern industry, basic theories are very important. For example, the basis of the straightening single crystal production process is Jan. Chakrassky's Czochralski crystal theory. In mechanical process theory, there is no finite element method theory of structural mechanics. Without modern CNC machine tools, in the field of metallurgy, without the theory of microcrystalline evolution, there would be no birth of super steel and microcrystalline alloys.
The cooperation between Shenyang Aircraft Industry and the Northeast Aviation Industry Research Institute is still in-depth, including shock wave theory, small aspect theory, and delta wing aerodynamic coefficients. The two institutions work together on turbojet, turbofan, turboshaft, and turboprop engines. During the development process, Shenyang Aircraft Research Institute basically conducted process research, and Northeast Aviation Research Institute conducted theoretical calculations and inferences.
The possibility of technology exchange between companies is very low, unless they purchase technology patents. However, within the theoretical research institute, although the Northeast Aviation Industry Research Institute and the Shanghai Aviation Industry Research Institute have always been very important competitors, the exchanges between the two parties in the theoretical field It is still very frequent, and Shanghai Institute of Aeronautics and Astronautics and Jiangnan Fudao Company are also extremely important scientific research alliances. Through theoretical breakthroughs and dissemination, domestic companies have the foundation to jointly expand their technological and technological capabilities.
Generally speaking, the Empire is a relatively special country in the world of scientific research. The driving force for the advancement of the Empire's scientific research field mainly comes from three aspects, namely the state, enterprises, social institutions and universities. The three aspects combine and cooperate with each other. Jointly promote academic theory, applied theory and applied technology research.
It is indeed a time of war, but driven by huge military expenditures, the empire's national investment in scientific research in 1940 will reach a new high and will account for 7% of the gross national product for the first time.
This ratio is very, very high, which means that the empire’s total national scientific research funding in 1940 will exceed 17 billion Chinese yuan. Even if Germany, a crazy country, is included, the total scale of the Chinese empire’s scientific research investment in this year It is also equivalent to the sum of the seven countries including Britain, France, the United States, the Soviet Union, Germany, Japan, and Italy.
Of course, the total national output of the Chinese Empire in 1940 was equivalent to the sum of the three countries of Germany, the United States and the Soviet Union - Germany was very powerful. After Germany annexed Austria and Czechoslovakia, coupled with the crazy expansion of its military industry and its active preparations for war against the Soviet Union, Its economic aggregate has been in the process of crazy surge, and in 1937 it had surpassed the extensive Soviet Union and ranked third in the world.
Judging from the total scale of the entire light and heavy industry, China, the United States, and the Soviet Union are definitely the four major countries in the world. Britain and France are no longer good. Japan does not have North Korea, Taiwan, and Northeast China is included in the calculation of output value. The actual scale is even worse. In addition, after 1933 Caught in a military competition with China, it went to the extreme level of militarism and caused great damage to the economy. By 1938, it had slipped behind Italy, ranking eighth among China, the United States, the Soviet Union, Britain, France, Italy, and Japan, and was abandoned by Italy. It has opened a large gap and is being caught up by Brazil, which has been developing rapidly in the past decade.
In 1938, China's gross national product was 1.83 times that of the United States, 4.6 times that of Germany, 6.3 times that of the Soviet Union, and 24.5 times that of Japan.
From this perspective, it is very glorious that Japan was able to survive the Third Sino-Japanese War until the second year, or even the third or fourth year.
As for Japan’s conclusion that China’s comprehensive strength is only about 7 times that of Japan, its military strength is only 2 times that of Japan, and the relative gap is not as big as during the Sino-Japanese War of 1894-1899, so that it finally concluded that “Japan has a higher probability of defeating China”, then It can only be said that Japan's subjective will determines its evaluation results, so it allows the base camp to tell lies with open eyes.
In such a powerful China, Shenyang is the brightest pearl in the Chinese crown.
As the birthplace of China's modern industry and heavy industry, Shenyang has had a unique foundation from the beginning. In the past thirty years, it has also led China to become the world's leading industrial country, and has also led Northeast China and Liaoning Province to become the world's leading industrial country. The largest industrial area.
In other words, Shenyang and the entire Northeast are too powerful.
Even though the central government's balanced development plan has been implemented for nearly 30 years, the total industrial and agricultural output value of the three northeastern provinces and the two Far East provinces still accounts for 1/5 of China's total output value. The five northeastern provinces plus Chahar Province are equivalent to All of Germany.
Liaoyang is the steel capital of China, Haizhou is the textile industry center in Northeast China, Aurora is the world's largest shipbuilding industry city and port city, and the world's third largest financial city, and Shenyang is the world's largest It is a center for the aircraft industry, semiconductor industry, and machine tool machinery industry. It is also the fourth largest textile city in Northeast China.
Shenyang already had a population of more than 13 million in 1933. The city was too big. After Gu Weijun came to power, he felt that this problem was getting more and more serious, so he forcibly introduced policies to split up Shenyang's automobile industry and food industry and move them to the south of the city. , part of which was moved to Changchun, and the chemical industry was moved to Fushun.
Especially in Changchun, the central government began to increase investment in infrastructure construction in Changchun in 1920 to share the industrial needs of Shenyang and at the same time promote the development of the entire Jilin Province.
Surrounding Shenyang, the central government also made a lot of adjustments in the six districts and six counties of Shenyang Prefecture. Yinzhou County and Fushun were included in Shenyang Prefecture, and Faku and Kangping County were taken out to build a circular city for Shenyang. , a three-layer ring-shaped light rail was constructed to connect Shenbei County, Shennan County, Shendanbao County, Yinzhou County, Xinmin County, Fushun Zhili County, and Liaozhong Zhili County as surrounding satellite cities of the entire Shenyang Prefecture Economic Region. , especially the combination of the four regions of Shenyang, Fushun, Yinzhou, and Liaozhong, plus Liaoyang, Jinzhou, and Haizhou, create a real Liaoning Province, and Aurora Prefecture is above this large industrial zone in Liaoning. portal.
Through the central government's major adjustments in recent years, Shenyang's development has grown significantly faster in recent years, especially driven by the military industry.
It does not mean that the economy will deteriorate once a war breaks out, especially for a country like China that is rich in labor resources and overall national strategic resources. As long as the war does not damage the fundamentals and does not affect domestic market demand and foreign imports. Export market, war will promote new growth of the national economy.
The impact on China was relatively large in 1939. By 1940, judging from the situation in the first quarter, the negative impact factors were already very low, and the positive driving effect was greater.
After Song Biao inspected Shenyang for the past two weeks, many of his initial worries have disappeared. His biggest worry is whether China's semiconductor industry can maintain its advantages in the long term. Now it seems that there is no problem at all.
In the past five years, if we pay more attention, invest more, build a deeper education and scientific research foundation, and train more talents, with the rapid expansion of the entire world's semiconductor industry and market demand, once China is the first to If it has a sufficient foundation in terms of advantages, it will be difficult to shake its dominance later on.
For example, in the field of microprocessors, Dongdao Company has invested funds and the best research teams to conduct pre-research on 16-bit and 32-bit. Although the current progress cannot be said to be smooth, it is not too bad.
Once this thing successfully achieves a breakthrough and is seven, eight, or even ten years ahead of Europe and the United States, even if the gap widens later, its dominance in the semiconductor and computer fields will be extremely difficult to shake.
Shenyang's semiconductor industry is mainly concentrated in the Southwest New District in the southwest of the city, close to Northeastern University and Northeastern University of Technology, while the aviation industry is concentrated in the northeast of the city.
Due to bad weather, the convoy waited for half an hour before arriving at the location of Shenfei Company in Qipanshan West District. This area is now under Shenbei County and is also the southeast side of Shenbei County.
The motorcade drove into the headquarters of Shenyang Aircraft Company. After Song Biao got off the car, he was accompanied by Jin Xiwu, chairman of Shenyang Aircraft Company, Sir Ba Yuzao, chief designer of the P7 project (in the history of the Republic of China, he died in 1929 due to a Japanese spy assassination) and Chen Qicai. Went down to the Shenfei Scientific Research Center Building, where we met with more than 40 important chief engineers and senior engineers.
These special and senior engineers at Shen Fei are generally not great scientists, but they generally have doctorates and master's degrees. For these people, the most important thing is always the combination of practical experience and theoretical knowledge. Of course, some of them are A master figure in the field of domestic aviation theory.
For example, Bayuzao is a compatriot of the Mongolian ethnic group. He was born in Zhenjiang in 1892. In his early years, he was selected to study mechanical engineering at Armstrong College in the UK. He first studied shipbuilding. After the establishment of the empire, through the coordination and contact of the Chinese Nationalities Committee, he soon returned to After serving in the United States, he was sent to study in the United States. While studying at the Massachusetts Institute of Technology in the United States, he transferred to the Department of Aeronautical Engineering. After graduation, he was assigned to work as an engineer at Curtiss Company. In 1930, after completing the design of the P-40 fighter aircraft, he returned to China. Served as a senior designer of Shenyang Aircraft Corporation Limited, engaged in the secret development of the P-6 turbojet fighter jet, and continued to serve as the chief designer of the P-7.
Because he couldn't go to the airport to witness the test flight of the new prototype today, Song Biao visited the two prototypes of the J-7 fighter at the scientific research center. There were two prototypes, which basically means that the aircraft is not yet finalized and put into production. Far away, at least that's what Song Biao thinks.
The J-7 is the first turbofan fighter in China and the world. Coupled with the previous testing of more than 20 types of test aircraft in the J-6 and P series, the Empire has accumulated some very important experience in the aerodynamic field. , at the beginning of the design of the J-7, three different air intake methods were considered: side air intake, belly air intake, and lower belly air intake. There are more ways to design the wings. Shenyang Aircraft Industry and the Northeast Aviation Industry Research Institute systematically For the hole test, a total of four feasible solutions are given.
The development code of J-7 is P-7, the P-6 in front is blank, and P-4\5 represent two large series of test models respectively.
Before the start of the project, the Air Force Staff reported relevant work to Song Biao. The plan was to develop a fighter aircraft with medium-air speed as the core, taking into account both high-altitude and low-altitude performance. This means that the performance of the aircraft must be balanced and able to As the main fighter aircraft of the empire in the 1950s, the J-6\8 was a supplement to the J-7 model.
Judging from the current service tests of the J-6, the side strips on both sides of the aircraft can still be enlarged. Therefore, after a series of demonstrations, the J-7 adopted a dual-engine close-range air intake layout on both sides, and the wings still inherited the J-6
-6's small aspect fixed upper monowing design, but the side wings are larger, adding a tapered twisted wing design and leading edge flaps, trailing edge flaps, canceling the J-6 wing blade, the overall characteristics are still emphasized
High subsonic combat performance requires extremely high altitude performance.
In order to further enhance the close-range combat performance, a dual-engine close-range arrangement was also chosen in the dual-launch configuration. This design is not conducive to the static stability of the aircraft, but is conducive to static instability. For this purpose, a horizontal program-controlled computer needs to be added, using the front
The edge flaps provide static compensation and stability to the aircraft.
At the scientific research center, the two prototypes Song Biao saw had the same layout. The only difference was that one might be slightly larger, with a higher nose and lower belly, which meant that the aircraft was thicker and heavier.
It's bad for combat performance, but good for range.
He was standing on a ten-meter-high steel platform and looking down. He could clearly see the difference in appearance between the two prototypes. From his perspective, the side wings and leading edge flaps also had different sizes.
The difference is that the middle width of the trailing edge flaps is different, so one aircraft has an arc-shaped trailing edge flap.
Because it is a turbofan engine, the structure of the rectangular inlet is obviously more complex and the air inlet is larger.
Song Biao took a general look and felt that it was still very good. If this aircraft can be put into service within five years, it will definitely be the first-class leader in the world.
It was unknown when exactly he would be able to serve, so Song Biao asked Chairman Jin Xiwu who was accompanying him. Jin Xiwu was also a senior engineer at Shenyang Aircraft Company and was very familiar with this project, but he did not dare to answer.
There was suddenly a strange silence on the entire platform.
After waiting for a few minutes, Sir Ba Yuzao, the chief designer of the project who accompanied Song Biao, replied: "It will still be difficult to put into service within five years. There are several problems that need to be solved gradually. The first is the problem of Northeast Heavy Industry's turbofan engine. At present,
It can be used, but the drawback is that the lifespan is a bit too short. Judging from the several tests currently conducted on P7, aluminum alloys and nickel-chromium alloys for some parts still lack some properties. The development of titanium alloys and niobium alloys has been ongoing.
, but it’s also very difficult.”
Song Biao said a little disappointed.
When he approved the P7 project, he made an estimate. The U.S. F-15 fighter jet also started development in 1965. The first prototype was produced in 1972. In fact, with the strength of the United States, it already had F-15 fighter jets in the early 1960s.
-15 production capacity, the problem is that the United States has made many mistakes. From World War II to the Vietnam War, it has not deliberately emphasized combat performance, and has long been suppressed by MiG fighters with poor technical capabilities in the air force.
It was not until 1968 that the United States made up its mind to change this situation. It completed the production of the F-15 prototype in 1972 and entered service in 1974.
The technological gap between the Empire and the United States in 1960 is mainly in niobium-titanium alloys, which are almost the same in the fields of aluminum alloys and nickel-chromium alloys. The Empire also started relatively early in the field of niobium-titanium alloys. In 1930, it officially entered the field of niobium-titanium alloys.
The institute is engaged in the development of niobium-titanium alloys.
In a turbofan engine, even the first generation turbofan engine uses at least more than 20 kinds of nickel, niobium, titanium, chromium, aluminum, and low silicon series alloys. Others are fine. The only one in the empire that is relatively weak is currently
It is a niobium-titanium series alloy.
This is also a very difficult thing, because titanium alloy itself is difficult to make. From 1930 to 1940, the empire invested as much as 300 million yuan in research funds in the titanium metallurgical industry alone, and there were six
The Metallurgical Research Institute specializes in the research of titanium technology, and it was not until 1937 that there was an initial industrial breakthrough.
From the breakthrough in titanium metallurgy to the development, research, and testing of titanium alloys, there is at least a ten-year cycle in between. In particular, the performance testing and process enhancement testing take too long. The alloy is made, but at what temperature and pressure
Lower processing can ensure the strengthening of properties and more effective processing. What is more complicated is how to deal with the welding process of titanium alloy?
The empire has invested a lot of manpower and financial resources in this field over the years, but there is really no reliable and fixed answer to this kind of scientific research.
Whether the P7 project can ultimately succeed and whether it can successfully meet the military's requirements depends on whether the turbofan engine can be more stable and stronger. The manufacturing of the fuselage also requires a large amount of titanium alloy. Current tests have proven that aluminum
The alloy can only maintain working conditions below 150 degrees in high-altitude and high-pressure environments.
If the environment exceeds 140 degrees, there will be serious deformation. If the fuselage frame and supports are made of nickel-based alloys, the weight of the aircraft will seriously exceed the standard. In the end, just like the MiG-25, which has good aerodynamic layout and high speed, the overall
Even though he is overweight, he still cannot have high combat performance at close range at the same time.
In addition, since the design of twin engines arranged in close proximity is not conducive to the static stability of the aircraft, the idea of using single-chip microcomputer and microcomputer programmable control for automatic adjustment and compensation for lateral stability is wonderful, but it is extremely difficult to practice.
After predicting that the P7 would be difficult to serve in a short period of time, Song Biao was a little disappointed, but he was not in a hurry, because in the foreseeable five to ten years, the J-6 with the second-generation turbojet engine would still have the capability to
The world-wide monopoly advantageous position is enough to secure a research cycle of about ten years for P7.
For early Japanese fighter jets, a research cycle of more than ten years is indeed enough.
Bayusao was quite courageous. Others did not dare to tell the truth, but he honestly reported all these things to Song Biao. After the success of the P-3 project, Song Biao met Bayusao once and personally helped him.
Awarded a First Class Baronet.
He was still very impressed by Bayama Zao. Although he hoped that the P7 project could succeed immediately, the development of science and technology must have its own objective laws, and it was useless to encourage the development of new projects.
Song Biao did not seem very anxious. Instead, he comforted Bayuzao, Jin Xiwu and others: "We want to design a jet fighter of the highest level in the world, and it is an epoch-making fighter. It is worth spending a little more time. If
It would definitely be worse to be eager for success and fall behind after just a few years of service."
After a slight pause, he encouraged Bayama alone: "Don't be in a hurry, take your time, and do your best if you do it."
Bayuzao bowed and said in thanks, "Your Majesty, the Holy Ming."
Song Biao joked with him very interestingly: "I am a very wise emperor, and you are also a very smart chief designer. If we cooperate well, China will be invincible."
Everyone laughed happily when they heard this, but Bayuzao replied in panic: "Thank you very much for the emperor's praise. The people must do their best to share the emperor's worries for the country."
Song Biao nodded slightly. Since this aircraft was basically impossible to be used in World War II, he didn't need to pay too much attention. It was good to take off and serve, but if it couldn't serve, the empire was not in urgent need for the time being. He pointed forward and signaled to everyone.
People accompanied him to the front to visit.
Along the way, Song Biao also took this opportunity to inquire with Bayuzao and other senior engineers about some new technologies and some of the main obstacles in the domestic aviation industry at this stage.
Generally speaking, the biggest obstacle currently comes from the field of materials.
Thanks to the long-term cultivation of Project 201, the empire's research level in the field of materials is about ten to fifteen years higher than that of Britain and the United States. Even so, as the empire begins to enter the development stage of higher-level turbofan fighters,
Basic industrial research still shows some shortcomings.
For example, for the rear axle of the high-pressure shaft of the high-pressure compressor, the 3-chromium-molybdenum single crystal steel used in the J-6 turbojet-5 engine is not very suitable, but this is already the current domestic standard in pressure resistance, high temperature resistance and
The material with the strongest corrosion resistance, this shaft steel also involves a more complex material selection issue for the turbine high-pressure shaft.
Why is it said that the F-15 can only be successfully developed in the 1970s? There are many problems. The biggest restriction is materials.
As for whether it is okay to use 3 chromium molybdenum single crystal steel for hardening?
Yes, absolutely ok, but its temperature is too high, the corrosion resistance and resistance coefficient under high temperature and pressure are not up to standard, and the overhaul time and total life will be very short. It will take two hundred hours... or even one hundred hours to replace it.
.
Why were aircraft developed so quickly and built so quickly during the war?
A very important reason is that the material considerations are small and the lifespan is short, because the probability of the fighter 70 produced during the war did not exceed two hundred hours of life.
It should be said that the scale of the empire's research investment in the field of materials is still very astonishing. The state and enterprises have combined with each other. The total scale of R&D investment in the past twenty years is more than the United States, the United Kingdom and the United Kingdom combined. In the entire materials discipline, metal is only
A very small part, such as semiconductors, rare earths, plastics, silicon, chemical fibers, graphite and carbon fibers, ceramics, resins... and other materials, Empire occupies a high international advantage in the research of the entire field of large materials.
Materials and fuels are the basis of the entire world industry.
If the materials cannot be uploaded, there will be no need to discuss anything.
These problems encountered during the development of the J-7 are enough to show that there is still a lot of room for development in the Empire's research in the field of materials science, and there are still many problems that need to be overcome.
Song Biao spent the whole day at Shenfei Company. In addition to inspecting the development projects of J-7 fighter jets, S-20 large turbofan transport aircraft, and SU-5 high-altitude and high-speed reconnaissance aircraft, he also inspected the development projects of Shenfei Aircraft Company.
There are several other ongoing development projects of the Aircraft Company.
In the past few years, J-5 series Tiger Shark fighter jets, J-6** fighter jets, S-10\15 transport aircraft and their series of aircraft, and the first-generation Z-3 helicopter that was officially put into large-scale service in the Army were all Shenyang aircraft.
The company's representative products.
Because production capacity cannot keep up with demand, the production of J-5 Tiger Shark series fighter jets has been subcontracted to Taiyuan Aircraft Manufacturing Company, Tianjin Aviation Machinery Company and Beijing Aircraft Engineering Machinery Company. Shenyang Aircraft Headquarters focuses on the production of J-6, and other companies Spare parts are also produced according to standards.
The S-20 large turbofan transport aircraft project is currently still competing with the S-30 project of Jiangnan Fudao Company. Both parties are striving to launch a real prototype first, but the problems of both companies are the same, and both parties are subject to for each other's turbofan engines.
The earliest turbojet engine in the Empire was born at Jiangnan Fudao Company. At that time, it was a relatively simple centrifugal structure. Later, after the axial flow design structure was introduced from Germany, the first generation of axial flow turbojet was designed and produced by Northeast Heavy Industry. After that, Jiangnan Fudao cooperated with Fuzhou Heavy Industry to produce the second-generation single-rotor afterburning axial flow turbojet engine, while Northeast Heavy Industry used a dual-rotor afterburning axial flow turbojet engine. The road thereafter followed Completely different.
In the process of researching turbofan engines, Jiangnan Fudao and Fuzhou Heavy Industries parted ways. The former adopted a single-rotor front fan afterburning axial flow turbofan engine and adopted a high-pressure ratio design, while the latter adopted a single-rotor rear fan afterburning axial flow low-pressure ratio design. In terms of design, Northeast Heavy Industry adopts a dual-rotor afterburner front fan high-pressure ratio design.
This allows the Empire to have three different turbofans at the same time. In the S-30 plan launched by Jiangnan Fuda Company, Jiangnan Fuda directly selected turboprop engines, while Shenyang Curtis Company, a subsidiary of Northeast Heavy Industry, continued to use turboprop engines. Fan engine, this is because the S-20 plans to transform into a bomber and directly become a new generation of long-range bomber after transformation, while the latter plans to transform into a large passenger aircraft.
In fact, both companies feel that they are on the wrong track, but this is also a problem of thinking and prediction that will be encountered during this era. Whether it is Northeast Heavy Industry, Jiangnan Fudao, or Fuzhou Heavy Industry, the three aviation industry giants are not Think jetliners are necessary.
From this point of view, the S-15 of Northeast Heavy Industry is indeed the last generation of propeller transport aircraft in China, and the double-row 24-cylinder radial air-cooled engine it uses has also reached the ultimate level of propeller transport aircraft. The huge body and aviation fuel The carrying capacity also makes it the first large transport aircraft that can fly directly across the Pacific Ocean and across China and the United States.
If all goes well, the current research and development plans of the empire can be successfully completed before 1945, and the overall level of the empire's aviation industry will completely surpass that of Europe and the United States, which is roughly equivalent to the level of Britain and the United States and other countries around 1955, and the fastest The British Rolls-Royce Company did not start developing the first-generation turbofan until about 1948, while the Empire was about ten years earlier.
Ten years ahead, this cycle is very important.
Of course, as soon as these secret development plans of the empire are made public, Britain and the United States will definitely accelerate the pace and launch relevant projects to compete with the empire. Then they will be able to realize this plan almost before 1950.
In general, the overall technological level of the empire at this stage has a lead of more than five to ten years compared with the United Kingdom, Germany, the Soviet Union and other countries. The largest lead is in the electronics, semiconductor and missile industries. These fields are indeed very powerful, but they are also There is a very close relationship with the samples from a certain base.
After Song Biao inspected the Northeast, he has been thinking about a question, that is, whether this advantage can be expanded.
The easiest way is definitely to continue to increase investment in scientific research. What else?
Song Biao's thinking is that there is no other more effective method. Scientific research is the pillar of human progress and the pillar of national progress, and the source of this pillar is education.
At this stage, the scale and proportion of investment by the Chinese government and enterprises in the field of scientific research have reached the limit under normal circumstances. The investment by the Chinese government and enterprises in scientific research and education is the highest level model in the world, even if
Nor can it compare with the United States. In terms of investment ratio alone, Germany's investment ratio in education and scientific research is at the same level as China's. China's strength over Germany lies in its larger economic aggregate.
To further promote the development of education and scientific research in China, the only force that still has room to speak of is social institutions.
Among social institutions, the Royal Academy of Sciences and the Inner Court Educational Research Society are undoubtedly the most powerful. In the past few decades, the royal family has indeed spent a lot on education and scientific research in China, but a huge part of the investment has been concentrated in nuclear power.
In the fields of industry and nuclear weapons, it is indeed time to change this status quo. (To be continued. Please search Piaotian Literature, the novel will be better and updated faster!)
