After all, the use of metal as aircraft material is an inevitable result of the development of the aviation industry. It is also an inevitable trend for wooden airframes, which are difficult to withstand large overloads and have poor sturdiness and durability, to be eliminated. The Soviets used wood to make aircraft.
This is due to the lack of a sufficient quantity of qualified aluminum alloys for the aviation industry and the understanding that aircraft are just consumables and that the cost of large-scale mass production should be reduced as much as possible.
The reason why the Anti-League still used wood at the beginning was mainly because the amount of aviation aluminum supplied by the United States was insufficient and could only be used in the production and manufacturing of bombers. It was a helpless move because the Anti-League was unable to refine its own aluminum products.
.
This Yak-9 fighter is still designed according to the Soviet Union, with steel pipes and canvas as the main structure of the body, and mainly wooden wings. The same is true for the Il-2 attack aircraft manufactured by the Anti-Japanese Alliance, with the rear half of the fuselage made of wood.
However, unlike the wings of the Il-II Company produced by the Soviet Army in the later period, which were all made of wood, the wings of the Il-II Company manufactured by the Anti-Japanese Alliance were still made of aluminum.
However, after recapturing Fushun, the Anti-Japanese Alliance immediately mobilized manpower to resume production in the Fushun Aluminum Factory, which had been destroyed during Operation Harvester and had never been able to resume production, in the shortest possible time. And through the production of B-24 bombers and C
After the 47 transport aircraft mastered the technology of making metal aircraft, they changed the Yak-9 fighter and Ilyushin-2 attack aircraft to metal structures.
Therefore, this group of carpenters did not produce aircraft for a long time, but it was enough for these people to have bragging rights a few years later. Although they did not know at all what the carpentry work they did was used for. They only knew
What's more, the wood back then was very hard and the craftsmanship required was very high. Even if you were not an experienced hand, you couldn't meet the needs.
But no matter what, these carpenters made a considerable contribution to the production of these two aircraft. It can even be said that without the participation of these old carpenters, the time for the production of these two aircraft would have been far away. After all, the aircraft drawings have
Yes, although there are a certain number of engines in stock, this does not mean that the aircraft can be put into production immediately.
From design to manufacturing, an aircraft requires not only design capabilities, but also production capabilities. The manufacturing process level of Anti-Lian is too low. If all are made of metal aluminum, even if Americans can meet the needs of aviation aluminum alloys, I am afraid that
It cannot be produced even with four or three years of anti-union technical capabilities.
The Anti-Japanese League truly formed its all-metal aircraft production capacity after the third and fourth batch of workers who went to the Soviet Union's Amur Komsomolsk Aircraft Factory for further training and after the Americans transferred B-24 bomber manufacturing technology to the Anti-Japanese League.
Only then did it form its own all-metal aircraft manufacturing capabilities.
However, the Americans have always controlled the quantity when it comes to the aid of aviation aluminum. Even if you can make B-24 bombers, they strictly limit your production quantity. The production and manufacturing technology and process of aluminum alloy products for aviation
standards, and even implemented a strict blockade against the Alliance. Even if you have the technology, you will not be able to produce aircraft due to lack of raw materials.
Kang Lian's request to order a 12,000-ton forging die hydraulic press was rejected without hesitation. However, after discovering that Kang Lian absorbed the technical capabilities quickly, he mastered the manufacturing technology of these two aircraft in a short period of time.
And relying on the workers and equipment rushed out from southern Manchuria, we are seizing the time to build our own aluminum alloy factory.
Its aviation industry, from upstream to downstream system construction, has gradually begun to form a complete prototype. Although this prototype is still quite immature, most of the factories have not yet been put into production. However, the United States feels that it may cause trouble for its China policy.
People immediately tightened their grip and stopped transferring any aviation and power technology to the Anti-Japanese Alliance.
Not only the technologies involved in the aviation industry, including non-ferrous metal smelting, special steel smelting, and even the transfer of oil mining technology, have gradually begun to shrink in scale. In addition to oil exploration and drilling equipment, and coal mining equipment, the rest of the industrial equipment
In addition to providing, the scale is always strictly controlled.
After the Japanese officially announced their surrender, the Anti-Japanese Alliance had a confrontation with the US troops who landed in Japan, and after the incident with the remaining Japanese navy ships, the Americans immediately demanded that all more than 2,000 experts and technicians working in the Northeast immediately leave the Northeast and return.
Domestically, its orders and attitudes are so tough that they are almost rarely seen in American history.
The U.S. government warns experts and technicians who come to work in Northeast China that if they do not leave China within a month, they will be severely punished by expulsion from their nationality. And those Chinese students studying in the United States who come to work in Northeast China, if they refuse to return to the United States or return to Chongqing,
He will be banned from entering the United States for the rest of his life.
At the same time, the Anti-Japanese Alliance and the secret representatives of the Northeastern People's Government in the United States are required to immediately leave the territory of the United States. Chinese students studying in the United States are restricted from returning to the country, whether they go to Kuomintang-controlled areas or base areas behind enemy lines. All American companies are strictly prohibited from exporting to Northeast China and other countries.
North China exports any industrial equipment.
But at this time, it was too late for the Americans to tighten the gap they had opened. At first, they always thought that even if the Chinese had a complete set of drawings of these two aircraft, with the Chinese's technical capabilities, it would definitely not be possible in a short time.
Americans who can truly master manufacturing technology underestimate the Chinese.
Little did he know how determined Yang Zhen was, who had planned all this. When it was the most difficult time to imitate the Merlin engine, when many people even wanted to give up, Yang Zhen personally talked to those fledgling technicians.
Encourage them to go ahead with all their plans.
When problems arose in aircraft production technology, Yang Zhen sent a large number of workers to the Soviet Union through exchanges to export free labor services and learn aircraft manufacturing techniques. He also sent a large number of foreign students to study aeronautical engineering in the Soviet Union at all costs.
.They even spent a lot of money to acquire a large number of prisoners of war who were German skilled workers from the Soviets.
Although when the Americans transferred these two aircraft manufacturing technologies, students studying in the Soviet Union had just begun to return home. However, the Chinese who had already laid down the foundation were no longer limited to the stage of assembling aircraft parts, but had begun to master the skills.
Aircraft manufacturing processes and technologies.
At the same time, by imitating the Merlin 27 engine used by the Hurricane IV fighter jet, they mastered the advanced engine manufacturing technology of the West. It is precisely with these foundations that the Anti-Japanese Alliance was able to absorb these two aircraft in the shortest possible time.
With its manufacturing technology, it has initially achieved the production capacity of large aircraft.
Even though the Americans rejected the Anti-Japanese Alliance's request to order a 10,000-ton forging die hydraulic press, the previously imported twelve forging die hydraulic presses with a capacity of 1,000 to 5,000 tons have gradually solved the problem of forging components required for large aircraft manufacturing.
By the time the Americans thought of tightening their mouths, it was already too late. Although their body bones were far from strong, the wings for soaring soon grew.
As for those carpenters who made corresponding contributions to the Chinese production of aircraft, Yang Zhen did not forget them. Although he could not give them too high salaries, he gave them great honors. After all these people quit the front line of aircraft manufacturing
Afterwards, the Northeast People's Government issued first-class Red Flag Construction Medals and third-class special labor model medals to all these people.
These two medals and medals are specially designed by the Northeast Bureau to award workers who have made outstanding contributions in industrial and agricultural production and construction. The first-class Red Flag Medal is the highest among medals, and the third-class special labor model medal
Although it is the lowest level among medals, the number awarded is not very large.
These medals and medals were given to a special group of people who are the cornerstones of China's aviation development after discussions between the Anti-Japanese Federation, the Northeast Bureau, and the Northeast People's Government. In recognition of their contribution to the development of China's aviation industry
Contribute.
For Yang Zhen at the moment, the most important thing is to consolidate this most basic foundation. Tall buildings are rising from the ground. No matter what the future development will be, this foundation must be laid now. So after this war is over, the Anti-Japanese Alliance will
Will be on the defensive for a long period of time to recover.
Throughout the second half of 1942 to the first half of 2003, in addition to focusing on the expansion of the army, the adjustment and replenishment of personnel, and the manufacturing and updating of equipment, Yang Zhen also focused a large part of his energy on the aviation industry.
Consolidate the military industry and formulate sustainable development strategies.
Although the Americans did not provide much equipment, the provision of military raw materials and equipment at this stage basically met the requirements of the Anti-League. In addition to heavy bombers, the Anti-League changed a large part of the aid share to machines.
Equipment. This is exactly what the Americans, who have been rattled by the successive protests in Chongqing, like to see.
The Americans really closed their mouths after discovering in early 1945 that the Chinese had completely mastered the manufacturing technology of the B-24 bomber. As for 1943 and 1944, the Americans had made great progress in industrial equipment and the transfer of some technologies.
, the opening is far from that tight.
Improving the Anti-Japanese Alliance's own military manufacturing capabilities as much as possible and strengthening its hematopoietic function during the war will undoubtedly greatly reduce the diplomatic pressure on the United States. This stage lasted until the second half of 2004, and the United States
Although the transfer of industrial equipment and technology is a bit slow and the agreement is not fully followed, overall it should be said that it is relatively generous.
Combat equipment is mainly concentrated on tanks and various tactical aircraft. Equipment such as artillery that is really used for infantry is dispensable. Yang Zhen is naturally optimistic about this approach of the Americans. From the Soviet Union
Although the third-hand equipment obtained from others is third-hand, it is still enough to deal with the Japanese.
If he also wants to occupy a share, then it is better to focus on industrial equipment. As long as the Soviets can provide enough German spoils, he does not care about the Americans' breach of contract on equipment. He knows that it will be a matter of time to fall out with the Americans.
Taking this opportunity to invest in more machinery and equipment is more suitable than in Northeast China.
Although they were quite dissatisfied with the consequences of Yang Zhen's Harvest Action, the Northeast Bureau and the Northeast People's Government still welcomed those skilled workers. After eliminating some unreliable workers, a large number of remaining workers were employed in the Northeast Industry
It played a huge role in construction.
Just as Yang Zhen originally judged, although there were not many skilled workers among them, this group of skilled workers alleviated the shortage of qualified workers for factory construction, and the training speed could not keep up with the gap of factory construction. After the arrival of this group of workers, it turned out that
The automobile and tank manufacturing industries, which were unable to produce qualified products, have developed greatly.
Especially in the tank and aircraft manufacturing industry, those workers rushed out from Fengtian Nanman Aircraft Co., Ltd. and the September 18th Tank Overhaul Factory solved a big problem. The first tank made by the Chinese was the first one made by themselves.
