Sound barrier, this is a problem encountered in the field of aircraft, and the ground motor vehicle has nothing to do with it, after all, motor vehicles on the ground, rarely more than 500 kilometers per hour, but in the air, it is easy to approach the sound barrier, if you want to the future aircraft and missile field, there is enough strength, the sound barrier must be broken, for the sound barrier, and even aerodynamics, Yang Yuanzhao in the current situation, even as good as the ordinary engineer who specializes in this field, he can not give a direct solution, but in the future, In the 21 st century, in the era of great information development, even if Yang Yuanzhao did not understand the basic theory, but on the Internet, countless articles and pictures, especially the latter, he had an impression of the basic form of missiles, and according to his impression, he drew down the forms of relatively common missiles, slender round bodies, narrow wings in the middle, and tail fins, all of which were unique forms of missiles in later generations.

In order to ensure the success rate, after all, the advanced experience of later generations cannot be fully applied to this era, after all, the missiles of later generations do not know how many generations have passed, in the step by step research and in-depth, the system of later generations has been formed, fortunately, Yang Yuanzhao recorded a lot of missiles, many of them are still large carrier rockets, he has been drawing for so many years, and he has experience in drawing, but he has drawn a few figures, and soon drew dozens of them, all of which are generally above, without a clear ruler, It can't even be called a view.

Although these forms can't tell these experts why they use this state to solve the problem of sound barriers, they can help them make physical objects, in fact, after the rapid development of China's science and technology and reached a certain depth, most of the role played by Yang Yuanzhao is this, using the experience, physical objects, and pictures of later generations to guide and inspire these scientists, and sometimes a flash of inspiration can solve most of the problems.

Researchers are already quite familiar with Yang Yuanzhao's practice, they are looking for inspiration on these figures, and compared with the gourd to draw a scoop, most of the forms can not play a role, in accordance with the appearance of these figures, the rocket samples made, not only do not play a role in propelling the speed of the rocket, but have a huge obstacle to the speed of the rocket. The reason why the performance of many weapons and a lot of new generation things in later generations is so good is that in computing, with more advanced algorithms and more excellent calculation tools, the final result is that the sensitivity and power of the missile are very great.

Just like the shape of the ship, the warships of later generations are often square sterns, the reason is very simple, under the high speed of sailing, the resistance is reduced, but under the premise that the speed does not reach this level, the square will increase the resistance, for example, when maintaining the economic speed of the ship below 18 knots, the square tail will hinder the increase of speed and waste power, so most of the warships of later generations did not use economic speed, even in the non-war state, it is rarely lower than 20 knots.

Technological leadership is not omnipotent, good things must be in a specific environment, will have a good effect, did not meet this standard, but has a bad impact, many of the future generations of missile form, are in the speed of Mach 3 or more, highlighting stealth performance and defense breaking performance, now even the basic has not been done, at most is close to the 700 km sound barrier category, and those super missiles in the 21st century, the difference is not a little bit, let alone these advanced performance, It's just that the initial elementary has reached the sound barrier, and it is impossible to even cross and break through.

Yang Yuanzhao drew a lot of graphics, some are very advanced, some are backward, one of the simplest middle wing and tail wing, it looks very simple, very heavy, it seems to be to increase the strength of the wing, not lift and stability, in the absence of other options, the researcher chose such a one, and only such a one can be chosen.

The previous diagram inspired the researchers, and derived from this many types of rockets, not only rocket artillery vehicles. Science, is in the continuous attempt, continuous failure, gradual progress, with the support of abundant funds, rocket research is still continuing, any possibility can be tried, made, just let it out, failure is to accumulate experience, what if it succeeds?

Everyone knows that the possibility of success is very small, but this time, after getting it right, not only did it succeed, the performance was very good, the stability was improved a lot, the flight attitude was more stable, the air resistance was decreasing, the range was also increased a lot, and the overall power of course rose a few notches.

Why is this happening, because the problem of breaking through the sound barrier has overwhelmed everyone, and even high-speed flying objects cannot exceed 700 kilometers per hour, just like in history, the difference is that the problems they encountered are more sudden, and more avant-garde, if it were not for the drawing given by Yang Yuanzhao, maybe it would have troubled China for one or two decades, in history, from the appearance of the sound barrier before World War II, until after World War II, it has not been solved, or in the Cold War period, the United States and the Soviet Union frantically invested in weapons and equipment, under the huge investment and serendipity, the sound barrier was solved.

This time, Yang Yuanzhao used the experience of later generations to solve the problem, the first test, because it was a little conservative, the speed was only fixed at 200 meters per second, that is, 720 kilometers per hour, which is probably the entry level of the sound barrier, and then, there is a continuous increase in speed.

Any research is easy to do with the real thing, according to the physical research, and analysis of why this is so, it is a great promotion of aerodynamics, especially the progress of the sound barrier, for the operation of the sound barrier, the general impact, and after breaking through the sound barrier, the changes produced by the record and research, Yang Yuanzhao drew the graphics, carried out a lot of calculations, and after the tail was added, a more mature rocket launcher appeared.

Because the processing of this rocket launcher is not very easy, it is a 3-tube parallel form, not the 12-tube in the previous exercise, without taking into account the power problem, reducing the power of the rocket engine and the amount of liquid fuel, the range has been reduced from 60 kilometers to 45 kilometers, but the accuracy has been improved too much, after careful calculation, the final result is expected to reach 280 meters, or even 160 meters.

Before 500 meters, no matter how hard you try to cover, there are always omissions, which is also the biggest problem of rocket artillery, but it is reduced by half, and when it reaches 280 meters, the coverage is basically uniform enough, as for 160 meters, as long as there are more than 120 rocket launchers, it is almost full coverage, the density of the attack is there, and the power will also be there.

The reason why such an amazing effect is achieved is very simple, the rocket without a tail is difficult to guarantee the flight attitude, there will be a large number of errors, a slight deviation, the rocket does not know where to run, but after the addition of the tail, the stability has increased greatly, and the accuracy has increased to a certain extent.

This is still under the premise of low-density loading fuel, and if enough fuel is loaded into it according to the previous standards, the range can exceed 60 kilometers, or even 80 kilometers, without any problems.

With the help of the accumulation of aerodynamics, China has produced accurate rocket artillery, in this regard, it is enough to excite people, the most critical death, after gradually mastering a large number of data, especially in the design of the tail, both to ensure stability, but also to ensure the range, in fact, the increase of the tail, not completely reduce the range, to a certain extent, in the case of increasing lift, you can even increase the range, as long as the angle is adjusted, plus the rocket engine and fuel, These are all matters in the field of materials, and if these aspects are solved well, the range of the rocket can even be improved to a certain extent.

A tail seems to be a new world, and it is completely different from before, the emergence of the tail, so that the rocket power and aircraft power are somewhat combined, can cruise launch, even higher missiles, also began to develop, stratosphere, with the help of advection stability, can be largely surface, reduce fuel consumption, and larger rockets, even giant rockets are also being established.

Although Yang Yuanzhao did not plan to get the satellite out in advance, the necessary technical reserves are still required, and the basic development of the rocket is successful, so both missiles and rockets need to be carried out, and rockets are their foundation.

Yang Yuanzhao also pioneered the situation of three-layer rockets, with the help of three-stage rockets, separation and strengthening, providing sufficient thrust to form a larger range, in order to solve the problem of individual rockets, constantly increasing, the problem of insufficient aerodynamic force and fuel, and the detached body, will make the overall weight of the operation will be lighter, and the corresponding speed will be faster.

As for liquid fuel, Yang Yuanzhao doesn't know, only from the polymer materials to prepare, from the oil extracts, to find higher energy, with the help of petrochemical propulsion, separation and combination of more powerful energy propulsion materials, rocket engines, and aircraft engines, from here, it is completely different, no longer considering stability and sustainability, more reflected in explosiveness, as long as it can adhere to the range of the rocket, as long as the speed of the rocket is fast enough, Maybe 60 kilometers only takes a few minutes, if it is not easy to get something that supports hundreds of hours, thousands of hours, or even tens of thousands of hours, but to get something out of ten minutes, as long as it is guaranteed to be within ten minutes, it can withstand high temperature and super power, this is no problem as a rocket material.
