Chapter 766: Dongfeng No. 2: Im going to be hot on horseback!
Just as Qian Wushi and others were looking up at the sky.
Uh-huh...
Ten seconds after taking off from Jiuquan Base.
The follow-up program of the Dongfeng-2 ballistic missile was automatically activated and immediately entered the program turning stage.
Rumble…
The gimbal bracket and vector motor equipped on the engine began to provide a deflection force to the missile, and the missile slowly began to tilt at a certain angle.
This is also one of the most common processes for rocket launches, which involves the concept of orbital angle.
Orbital angle is what it sounds like, it refers to the angle between the spacecraft's orbit and the equator.
This thing allows the rocket to be affected by less aerodynamic stress, and it can also use the gravity of the earth instead of its own fuel to change the direction of the rocket's flight, thereby saving more fuel for horizontal flight.
Its calculation formula is generally the orbital inclination of the International Space Station...that is, 51.65 degrees minus the local latitude. For example, Jiuquan is 41 degrees north latitude, so the orbital angle of the Dongfeng-2 missile is 10.65°.
This is why when people in later generations see the rocket launch interface, they will find that the rockets taking off are always getting more and more "crooked".
Then guided by the deflection force.
Dongfeng 2 slowly began to turn while still maintaining a very high ascent speed.
For most surface-to-air missiles, their effective combat altitude does not exceed 24,000 meters.
Because above this altitude, the air is too thin, and the missile's wings cannot control the missile's rapid steering. It is not suitable for dealing with small targets and is only suitable for attacking large non-maneuverable targets.
At the same time, their maximum combat altitude generally does not exceed 45,000 meters, and they can only shoot large, low-speed balloons at this altitude.
But intercontinental ballistic missiles are different.
Their theoretical ballistic peaks can usually reach 800 kilometers, and some can even exceed four digits - of course, this refers to the technologically advanced intercontinental missiles of later generations.
However, although the technological level of this period is different from that of later generations, the flight height is still not much different.
For example, Dongfeng 2.
Its preset flight top altitude is... 774 kilometers above the ground.
Rumble.....
The huge Dongfeng 2 turned while constantly breaking through the clouds and speeding towards the highest point in the sky.
Suddenly.
When Dongfeng 2 flew over a location, a small platform appeared not far away - of course, a quotation mark should be added to the not far away here. After all, in this height of reference system, there are many
What seems to be a very short distance is actually more than ten or even dozens of kilometers.
at the same time.
A red light flashed slightly on the surface of Dongfeng 2, and a green light also came from the platform in the distance.
The two objects, one big and one small, seemed to have come to life, and they said hello from a distance.
at the same time.
Jiuquan base.
An operator responsible for signal reception suddenly raised his head and reported to Qian Wushihui:
"Report! Dongfeng 2 successfully passed through the airspace where the Zhuxian platform is located. The altitude is 49,000 meters. The missile speed is about 0.79 kilometers per second."
Master Qian nodded slightly.
At present, the Rabbits are not capable of launching satellites. The Zhuxian platform launched when they shot down U2 is now the aerospace equipment with the strongest space-related capabilities in China.
Without carrying four Zhuxian Sword missiles, the height of the Zhuxian platform can reach 50,000 meters.
Of course.
The Zhuxian platform at this altitude basically has no practical significance. It can neither launch missiles nor collect a large amount of high-altitude data. It can only simply exchange some radio information and act as a mascot.
This time, the rabbits raised the Zhuxian platform to the highest altitude. The main purpose was to monitor the flight height and speed of the missile.
"0.79 kilometers per second..."
Master Qian turned around and looked at Liang Shoupan:
"Master Liang, you are amazing."
Liang Shoupan smiled innocently, looking like a forty-six-year-old child.
When designing the Dongfeng-2 missile, there was actually some controversy within the design department regarding the speed of the missile.
At that time, some engineers believed that this project was of great importance and that the results were greater than anything else, so the missile's flight speed could be reduced, so that the requirements for structure, materials, and fuel would not be so high.
This view has been endorsed by many people in the design department, and even some supervisors believe that this suggestion can be adopted.
The ballistic trajectory designed based on that view should have a speed of about 0.4 kilometers per second at an altitude of 49,000 meters.
However, the chief designer Liang Shoupan expressed strong opposition to this plan. Uncharacteristically, he even slapped the table and said three sentences:
"If we want to develop missiles that can be used in actual combat, what's the point of having a semi-finished product?"
"Throughout the entire new industrial history of the Republic, some projects did adopt relatively mild plans at the beginning, but which one of them was not limited by the technology and equipment problems at the time?"
"We now have complete design results, and the hardware can be fully compliant in theory. In this case, you have to shrink your eggs and produce semi-finished products? Are you still shameless?"
At that time, a certain leader in charge was a little uncomfortable being confronted by Liang Shoupan. After all, in this era, not everyone is passionate and indifferent to fame and wealth. There are people everywhere who are greedy for official positions and dare not take responsibility, so the leader reported the small report
We reached the capital.
The result was unexpected.
A concise and concise reply came from the capital that day, said to be from the mouth of a certain big rabbit:
【No appeasement!】
The word appeasement is much more serious in nature than those "shrinking eggs", and it can even be said to be a conceptual refutation.
So since then, the project team has unified its concept and sprinted with actual combat as the goal.
Among them, the design of the acceleration part of the missile was personally mastered by Liang Shoupan. He led the team to research for more than a month and finally broke through the speed limit in the turning stage.
This chapter is not over yet, please click on the next page to continue reading! As for the supervisor who came over to add seniority...
At that time, along with the reply from the organization, there was also a transfer order to a state-owned farm that was sent to the project team.
His eyes returned to reality.
After greeting the Zhuxian platform, Dongfeng 2 continued its liftoff.
48 seconds later.
The missile successfully passed through the Karman Line, and the primary structure began to separate.
This time, the missile designed by Qian Wushi and others has four boosters tied to one sub-stage of the rocket engine. There are two connection points between each booster and the first sub-stage, the front and the rear. The front connection point consists of 3
The connecting rods are connected in an "N" shape. Each connecting rod is divided into 3 sections, and each two sections are connected with explosive bolts.
This kind of explosive bolt is hollow and contains explosives inside. When energized, it will explode and break the bolt, causing the connecting rod to disconnect.
After the booster receives the separation command.
boom.....
The separation rocket on the booster was ignited first.
0.1 seconds later.
The explosive bolt and shaped energy cutting cable are detonated simultaneously, causing the front and rear connection points to be disconnected and unlocked.
Then, the four boosters left the core stage rocket with the thrust of the separation rocket.
Then the front-stage engine started igniting when the connector was unlocked, so after the booster separated, the high-temperature gas flow ejected by the front-stage rocket engine pushed the first-stage structure out smoothly.
The first-level separation is completed.
According to the design team's plan, the separated primary structure will be braked by the remaining propellant and fall, falling into an uninhabited area in Xihai Province.
at the same time.
The ignited second-stage engine pushed the second-stage rocket to accelerate forward, and then the fairing began to separate.
The separation process between the fairing and the rocket body is also called the shroud throwing process. It has three transverse separation surfaces and one longitudinal separation surface. Four pairs of hook-type rotating hinges are installed on the transverse separation surface of the fairing to enable the fairing to achieve horizontal push-rotation.
separation.
The longitudinal separation surface of the fairing divides the fairing into two half-covers, which are connected using a longitudinal unlocking mechanism. This longitudinal unlocking mechanism consists of multiple mechanical locks, connecting rods between the locks and a pull-type pyrotechnic cylinder.
When the missile flies for about 200 seconds.
Snapped.....
The 12 explosive bolts on the lateral separation surface of the fairing detonated simultaneously, and the lateral separation surface was unlocked.
It's still 0.1 seconds later.
The pull-type pyrotechnic cylinder works, and the pull rod is pulled to open all mechanical locks, so that the longitudinal connection of the fairing is released.
It's clear...
Sixteen sets of compression separation springs on both sides of the longitudinal separation surface of the fairing push the two half-hoods outward, causing them to rotate around four pairs of hook-type hinges on the transverse separation surface.
When turning to an angle of about 65°, with a clicking sound, the hook-type hinge automatically unhooks, and the two half-hoods are automatically thrown outward.
Six minutes later.
At the end of the acceleration phase, Dongfeng-2 reached a speed of 3.8 kilometers per hour.
To know.
Even in the later generations of Xu Yun's time travel, the speed of many intercontinental missiles before the end of the first stage was only about seven kilometers per hour.
At this stage, the mission of the missile is mainly to fly suborbitally along an elliptical orbit outside the atmosphere.
The apogee of the Dongfeng-2 orbit is about 774 kilometers from the ground. The length of the semi-major axis of the elliptical orbit is 0.65 times the Earth's radius. The projection of the flight orbit on the Earth's surface is close to the great circle line - the reason why it is "close" rather than "coinciding" is because
The deflection caused by the rotation of the Earth itself during flight.
Hula la...
While the missile is traveling through space, the radio equipment on the missile body is also transmitting its real-time position.
These radio signals sank through the sea of clouds and were quickly captured and analyzed by rabbit observation stations around the world:
"Report! The missile has passed Baiyin in the West Sea, flying at a speed of 3.9 kilometers per hour!"
"Report! The missile has passed Baoji, Shaanxi Province! The flight speed is 4.1 kilometers per hour!"
"Report! The missile has passed Nanyang! The flight speed is 4.1 kilometers per hour!"
"The missile passed Tongling! The flight speed was 4.2 kilometers per hour!"
"The missile passed Hengzhou!"
After a while.
An operator reported the last message:
"The missile's location passed through Yueqing, Zhejiang Province! It went to sea smoothly! Radio data transmission has been disconnected!"
After hearing the news reported by the operator, Master Qian clenched his fists again.
marvelous.....
The Dongfeng-2 missile is progressing steadily in accordance with the project team's pre-designed design in terms of flight path and various parameters, without any deviations of any magnitude.
Several reception points pre-arranged by the organization received the information from Dongfeng 2 on time.
This is obviously good news.
You know, even though the missile has just left the sea, it has actually flown more than three thousand kilometers - who made China's land so vast...
As for the positioning information returned by the missile, Qian Wushi was not worried about leaks. In fact, the Rabbits did not encrypt this information at all.
After all, this is just the positioning data returned by the missile. The only thing that can be 'leaked' is the missile's route, which is then traced one by one to the Jiuquan Satellite Launch Center by technology.
Today's Jiuquan Satellite Launch Center is different from the 221 Base. It is a well-known brand responsible for missile research and development tasks. The Rabbits launch all kinds of rockets openly every time.
The most secret part of the Jiuquan Satellite Launch Center is the hidden R&D center and factory buildings. There is no risk in a single location.
Before the bombing of U2, the Rabbits uncovered a spy with the pseudonym Chen Wenliang in Jinta County, and Jinta County was located next to the Jiuquan Satellite Launch Center - the enemy agents had long been eyeing this place.
Therefore, regardless of whether it is 'exposed' or not, the Jiuquan Satellite Launch Center will not be affected in any way.
Except for the Jiuquan base, those who intercept the radio can at most know where the rabbits have radio receiving equipment based on the location - but this 'intelligence' has a ghost meaning...
Even in this era, there can be hundreds of radio instruments in any small county.
Of course.
Although these radio data are very difficult for hostile forces to dig out some of the rabbits' secrets, they can prove another thing:
An aircraft with a maximum speed of Mach 11 is drawing an arc from the northwest inland of China and heading straight for somewhere.
Almost everyone is going crazy.
Mach 11...
Mach 11!!!
The speed of the current top fighter jets only fluctuates around Mach 1.5. Even the MiG-25's ultimate speed is only around Mach 2.83. The XB-70 across the sea, which is still in legendary status, can only reach Mach 3.3.
So this aircraft can never be a fighter jet or reconnaissance aircraft, it can only be...
missile!
At the same time, based on the radio's altitude, frequency and other information, these forces easily calculated an area of more than 100,000 square kilometers - the South Pacific!
Until this very moment.
Treasure Island, across the sea, neon, Tu'ao, furry bears...
Think tanks in countless countries have truly realized one thing:
The Chinese people have really never told a lie from beginning to end. They are really conducting experiments on ballistic missiles...
Swish——
At this moment, the big shots who were qualified to have access to this information all raised their heads and looked to the east.
Their sights seemed to travel through space, staring at the shooting star as if from another world. It drew a dreamlike bright arc in the deep night sky, just like the god's paintbrush spreading endless brilliance.
Then, from the fiery core of the meteor, an extremely high roar came out:
"South Pacific, I'm going to be hot on horseback!"
Didi didi...
In an instant.
Countless telegrams began to be transmitted quickly through various channels.
Although the contents of these telegrams are all encrypted, the meaning they express is the same:
We must seize the data cabin before the Chinese do!
And just when all walks of life are turbulent.
China's fleet in the South Pacific has also begun to take action...
