Preface
For all countries now, the development of science and technology has become the primary and top priority, after all, with science and technology can promote the development of their own country in the future, and at the same time, science and technology is also an important certificate that can affect the comprehensive ability of each country, and the progress and breakthrough of science and technology can not only promote the development of the economy, national defense and society, and even affect the changes in the world pattern.
Under such circumstances, science and technology have become the top priority of various countries, and even some countries are afraid that others will surpass them and "stumble" in private, which also proves how important science and technology is, and at this moment, the comparison of wind tunnel speeds between China, the United States and Russia has become a hot topic, but what is the wind tunnel test? What is the development of the mainland?
What is a wind tunnel experiment and what does it do?
Wind tunnel experiment is an exclusive term, many friends should not have heard of the topic of this experiment, and even many people do not know what it is for, can this be regarded as high-tech technology? In fact, the importance of wind tunnel experiment is mainly reflected in the national defense at all levels, there is the word "wind", you can guess it.
This wind tunnel experiment is mainly reflected in the military aspect, such as some aircraft, advanced missile technology, flight experiments and collision experiments, etc., and it is precisely for this reason that many netizens have not heard the name of this experiment, because it is a bit far from our lives.
But what exactly is the principle of this technology, or what is the principle of this experiment? In short, this kind of experiment is to simulate and practice many different ways of flying in a laboratory (or experimental space, so to speak).
And wind tunnel testing has been around for a long time, when the world's first aircraft came out, in the British laboratory, their scientists used wind tunnel tests to simulate the flight process of the aircraft from beginning to end, the purpose of which is to make the aircraft safer in the future.
Under this operation, the wind tunnel test can calculate a lot of data before the aircraft actually performs the flight mission, so that the aircraft will be safer and more stable when it is actually put into use in the future, which also has many knowledge points such as dynamics and aerodynamics.
Now we will look at the last century around the 50s (the end of World War II), many countries have carried out a large number of wind tunnel tests, because there were many aircraft at that time, until some scientists realized that some future aircraft are also inseparable from wind tunnel tests, and slowly this technology has been made many breakthroughs and developments.
In our current era, wind tunnel experiments have been frequently presented, and this experiment is not only used to study aircraft, but also has many applications in wind power generation, air environment, pollution detection and wind field testing, etc., and it can often be seen.
However, this is just to say that the wind tunnel test has been applied and embodied in many countries, not that many countries say that the wind tunnel test research is very thorough, and it is still very difficult to study the wind tunnel test in depth.
Because in the process of building a laboratory, the wind tunnel test needs to build a space suitable for the aircraft or flight equipment, and also pay attention to many aspects such as air flow changes, wind speed changes, etc., which are difficult to overcome.
Among them, the wind tunnel laboratory also needs to pay attention to the overall size of the laboratory, how to obtain power in this laboratory, etc., only after breaking through the difficulties in these aspects can we officially enter the research and progress of aircraft, aircraft, missiles and other aspects.
Speaking of which, we have to mention China, the United States and Russia, as the three permanent members of the world's Security Council, and also the world's most powerful countries in terms of comprehensive national strength, and their economic and financial resources invested in wind tunnel testing are very huge.
From here, it can also be seen that China, the United States and Russia attach great importance to wind tunnel testing, they all want to make breakthroughs in this aspect ahead of other countries, and they are also working hard in private, let's take a look at the development and comparison of China, the United States and Russia in wind tunnel testing.
Comparison of wind tunnel tests between China, the United States, and Russia
A very important point in the development of wind tunnel testing is whether all the parameters of the experiment can be stabilized, whether the parameters are accurate, etc., because these data are the parameters that can simulate the overall gas flow rate and gas flow rate, and only if these parameters can be accurate in the case of a very poor air flow environment, it is successful.
Only when these conditions are met, can it be proved that the accuracy of the wind tunnel test and the success of the experiment are relatively high, and then we will first look at Russia, there is a very powerful laboratory in the wind tunnel test in Russia called T128 wind tunnel laboratory.
This laboratory is also one of the most advanced wind laboratories in Russia, which can reach supersonic speed when simulating air flow and air velocity, and even the density of air flow in this laboratory can be controlled, which alone is enough to show that this Russian laboratory is very advanced.
After talking about Russia, there is the United States, the United States is also the only superpower in the world today, and in the United States has many technologies that are the world's top existence, and at the same time, the United States also has relatively advanced technology in wind tunnel testing, and there are many professional wind tunnel laboratories in Ohio alone.
These wind tunnel laboratories are basically all comparable to Russia, but they are also easier to understand, after all, the United States has so many advanced weapons and equipment, and they are very strong in aircraft, fighter jets, aviation technology and missiles, but this is not to say that the mainland's wind tunnel tests are worse than those of these two countries.
On the contrary, so far only China's wind tunnel laboratory in the world dares to say that it is the world's first, and even many times the United States and Russia feel that China's development is too fast, so let's learn about the development of China's wind tunnel test.
Wind Tunnel Laboratory in China
Speaking of China's development, the mainland was still poor and white a long time ago, and had no influence in the world, but with the rapid development of the country and the progress of science and technology, the mainland has gradually become one of the world's top scientific and technological powers, which is also reflected in the wind tunnel test.
Although the mainland is still relatively backward in terms of wind tunnel testing compared with other countries, especially compared with the United States and Russia, it cannot bear the fact that countless scientific researchers on the mainland choose to go abroad to learn Xi this knowledge, and the domestic government does not hesitate to spend a lot of money to introduce advanced achievements from abroad.
Later, however, our country's scientific researchers discovered that it was not possible to fundamentally improve the mainland's own technology by simply importing foreign advanced technology, because if I want to become a superpower in wind tunnel testing, I still need to master my own advanced technology and continuously improve in this aspect.
As a result, the mainland's scientific researchers have made up their minds to fundamentally change this status quo, and have drawn up a set of detailed development plans for this, in which the two most important points are "independence" and "independent research and development."
With the basic theories and knowledge, and some foreign cases and achievements, the mainland directly chose to establish the largest wind tunnel laboratory group in Asia in a certain area in western Sichuan, which has a variety of different wind tunnel laboratories, which can measure all kinds of data and simulate all kinds of different situations.
After that, the mainland set up wind tunnel laboratories in many first-class universities, such as Shantou University, Beijing Jiaotong University, Jilin University, and so on, so that more advanced talents could be trained.
epilogue
Now we have the J-series fighters, the Shenzhou spacecraft, and a lot of satellite technology, all of which are inseparable from the success of the continental wind tunnel test.
According to the United States, the wind tunnel test on the mainland has reached Mach 5-25, which is directly higher than that of the United States, and it is hoped that in the future, the wind test on the mainland will be more successful!
