Chapter 1676: Approaching the Sound Barrier

China in aerodynamics, because of a large number of aircraft equipment, has been very in-depth research, it is these studies, so that China to produce qualified large transport aircraft and bombers, the development of more powerful than the United States in World War II air force, in the process of aircraft research, for a variety of aerodynamic forms of research, produced a variety of different tails, ******, fixed wings, even swept wings have a certain amount of research, produced at least hundreds of various types of aircraft, in the middle of the best of the best, Pick out China's main combat aircraft.

Yang Yuanzhao in later generations, can only be called a pseudo-military fan, he also wants to make a sweep wing similar to the F14 Tomcat, but a little support, was defeated by reality, the Tomcat's swept wing is based on the level of fly-wire and automation control to achieve, although it is an aircraft that appeared in the 60s of the 20th century, but with China's processing level, at the beginning of the 21st century, it can not be imitated, not to mention this era, in automation and telex can not reach a certain height, this is just a fantasy, perhaps on the basis of the presentAfter twenty or thirty years of continuous development, it may be able to produce and appear, but now it is just a process of accumulation, and the swept wing is only fixed, and it cannot be actively adjusted according to the changes in air flow, and it cannot show the strong maneuverability of the Tomcat.

Rao is so, in Yang Yuanzhao's opinion, these accumulations are enough, and it is not difficult to solve the tail of the rocket. The Rocket Research Institute does not have the accumulation of this aspect, but there is a flying laboratory, and as long as you start from this aspect, you can still get support in this area.

Yang Yuanzhao attaches great importance to this project, even if the military has some complaints about this project, no one knows better than him that rockets and rocket-based missiles have an impact on future generations, it can be said unceremoniously that among the mainstream high-end weapons, missiles are basically used as weapons, whether it is the army, the air force, or the navy, missiles are the first series of attack weapons, only when all the missiles are launched, artillery and light weapons will be considered.

In later generations, missiles have changed almost the entire world, according to the performance distinction, divided into three areas of land, sea and air, so developed, different types of missiles, and according to different responsibilities, there are also offensive missiles, defensive missiles, and even individual missiles, it can be said that in addition to light weapons, most of the heavy equipment, if it can not be combined with missiles, it will not be able to play the maximum role, naval units and air force units, to a certain extent, just become a platform for weapons, the two sides meet, outside the line of sight, Depending on the performance of the missile and the performance of the radar, one side can easily kill the other side without damage.

Even aircraft carriers have a crisis because of missiles, and in the past aircraft carriers had a sufficient advantage over battleships, and the range of artillery tens of kilometers is hugely different from the combat radius of aircraft carriers of hundreds of kilometers. However, missiles are different, not to mention cruise missiles, with a range of several hundred kilometers, even if they are ordinary ship missiles, they are also in the range of 200 to 300 kilometers, and for aircraft carriers, the range of defense that must be defended has increased, from the original tens of kilometers to hundreds of kilometers, and this increase has played a huge threat to the aircraft carrier's protection capability.

China in all aspects of science and technology, has surpassed this era, with the development of the basis for the development of missiles, if not on the missile side, there is a more in-depth study, all the previous foundation, will be in vain, this is Yang Yuanzhao is not allowed, in the past, China also has to intervene in this field, Yang Yuanzhao will not be forced to improve, but now, China has touched this threshold, the previous exercise of the rocket, has a prototype of missiles, even to a certain extent, in terms of technical performance, It is much better than the originator of missiles, the V1 missile, it is just a rudimentary thing like a drone, and the hit rate is almost negligible, but China can form a similar covering attack, although there are some flaws, but it is acceptable.

Missiles are too important, after the plane, Yang Yuanzhao rarely intervened in China's scientific and technological system, for fear that some of his actions would break the foundation of the future, but this missile is not allowed to have problems, he not only tilted the funds for this project, but also drew a large number of charts, and handed over the theories heard in later generations to the project team.

Because of Yang Yuanzhao's attention, some experts in aerodynamics came to study the aerodynamic shape of these rockets, an unmanned aerial vehicle, using a high-thrust engine, this weapon is very eye-catching, in addition to the tail, try to add some wings and the like, to increase his stability and accuracy.

In fact, after joining these, the performance has been greatly improved, Yang Yuanzhao is also a good opportunity, he was not able to come in person, if he was there in person, he will definitely see that this weapon seems to be more and more like the World War II period, the German army V1 missile, the thick body, a simple tail, there is a straight parallel wing in the middle, which can give the rocket huge lift and stability, as far as the experimental results are concerned, it has basically met the requirements of the design, if it is a weapon like rocket artillery, This is ready for battle, with a lot more performance than the previous experiments.

The rocket is made more and more like an airplane, which is more or less a historical inevitability, but China in terms of dynamics, far more than Germany during World War II, after the use of various new materials, the speed is very fast, especially Yang Yuanzhao directly solved the fuel problem, using aviation kerosene as a raw material, adding some oxygen generator, to a certain extent, with the best mixing ratio, providing enough power, with the support of surging power, the speed of the rocket continues to accelerate, and the performance indicators are very satisfactory to them. At a range of 60 km, it took only 7 minutes at most to make the leap.

This has exceeded the speed of the fastest aircraft, but it is still lower than the speed of the shell, the accuracy of the rocket is there, but the speed is insufficient, the speed of about 650 kilometers, for the range, may be too slow, even if you aim at the opponent, unless it is a covering attack, otherwise, even the infantry can dodge, let alone mobile units. Speed is the key to a weapon, the reason why the machine gun is so powerful is because of speed, otherwise, even if enough bullets can be projected in a short time, without this speed, the opponent can easily dodge, no matter how much it has no effect.

This is not difficult for these aircraft power experts, China is not strong in other aspects, but the power is strong enough, increase the diameter of the rocket, even a little, it can provide a lot of fuel, plus oxygen generators, etc., equipped with excellent engines, it is enough to make the speed of the rocket to a higher level, in their gradual increase, the maximum speed from 180 meters per second, gradually increase to 195 meters per second, suddenly there is a problem, the power is greatly lost, although the power is increased, According to the calculated proportions, the speed that should have been increased did not increase significantly.

This is a problem, and did not attract the attention of experts, they continue to increase the power, when the power is increased to a certain extent, the rocket after continuous acceleration, in fact, is more than the speed of sound, to some extent, faster than the ultimate speed of the artillery, the simple mounted tail, not only did not work, but broke because of the impact force generated by the speed.

This is a huge problem, but also a problem that has never been found, caused the study of aircraft experts, Yang Yuanzhao thought that soon, will get the relevant experimental data and results, did not expect to wait for more than a month, once again to find the time, to care, he was stunned, this reason, he suddenly thought of an important problem sound barrier, 200 meters per second speed, 340 meters away from the factor There is still a certain distance, but it is an important node, a large aspect ratio of straight wing aircraft, When the flight speed is close to the speed of sound, there will be a sharp increase in drag, deterioration of handling performance and spontaneous planting, and the flight speed can not be increased again, so people once thought that the speed of sound is an insurmountable obstacle to the speed of the aircraft, hence the name sound barrier.

Yang Yuanzhao also thought that in this war, it was impossible to approach and break through the sound barrier, but he encountered it here, in fact, long before the rocket, most of the large-caliber artillery had exceeded the sound barrier, but after the artillery was shot, the speed decreased rapidly, and there was no sustainability of the speed, this performance was not enough to affect the performance of the artillery, but the rocket, like the airplane, is a continuous acceleration of the flying object, whether it can break through a certain speed, is the fundamental reason why he crossed enough distance. In this case, the speed is often above and close to the speed of sound.

To put it bluntly, it is an airplane or other flying object, when it is close to the speed of sound, the resistance of the air resonance encountered, generally speaking, the flying object heavier than the air, the flow speed of his surface airflow, is not balanced, often at a speed of about 700 kilometers per hour, it will be initially encountered, even if the engine power is enough, but because of all kinds of resistance, it can not continue to accelerate, only after breaking through the speed of sound, it can be weakened, and the resistance and other performance are greatly reduced.

This problem is not solved, the rocket produced can only reach subsonic speed, that is, below the speed of 700 kilometers per hour, under this speed, the penetration and combat effectiveness of the rocket can also be made, and the rocket artillery vehicle made in this way also has enough combat effectiveness, but Yang Yuanzhao is not just studying rocket artillery vehicles, he wants to rely on rocket artillery vehicles, accumulate some experience, lay the foundation for missiles, and even future jet fighters, also need to break through the sound barrier, do not solve this problem.
