Qian XuesenDigging a big hole years ago, the whole world is jumping now.
In 1946, Qian Xuesen proposed the concept of supersonic flight, which most people were skeptical about at the time. They believe that with the level of technology 70 years ago, it would be extremely difficult to achieve the speed of a car at hundreds of kilometers per hour, let alone supersonic flight.
However, in that era when science was not popularized enough, it was difficult for ordinary people to understand the concept of supersonic speed. However, Qian Xuesen's idea was quickly realized by the American academic circles.
Inspired by the theory of "supersonic speed", they created the first supersonic fighter X1 in 1947. The appearance of this fighter is of epoch-making significance, it represents the first aircraft in the history of mankind to exceed the speed of sound.
In general, the speed of sound can reach 15 meters per second when the temperature is kept at 340 meters. The X-1 fighter had a speed of 1Mach 06, which is equivalent to flying 360 per second72 meters at a distance.
It is not difficult to see that the flight speed of the X 1 fighter is already quite high. However, in fact, this fighter is only the initial stage of the American supersonic vehicle. In the following decades, the United States upgraded and rebuilt supersonic fighters almost every year, and the speed of the new supersonic fighter has long reached 500 meters per second.
It can be said that the United States is already ahead of the curve in research in the field of sound, thanks to its great military power and financial resources. However, in any case, the appearance of the X-1 fighter is of great significance, as it marks that the military development of mankind has entered the stage of implementation of the hypersonic theory.
At that time, China was at the critical juncture of the War of Resistance Against Japanese Aggression and the War of Liberation, and was unable to take into account cutting-edge scientific research. After the founding of the People's Republic of China, the military industry was in its infancy, and foreign support became the main means of construction in many fields, and the development of the supersonic field was temporarily shelved.
However, after comparing the military strength of China and foreign countries, people of insight believe that it is necessary for China to conduct research on hypersonic speed. The reason is that with the development of science and technology, many countries have entered the era of missiles, which are far superior to ordinary artillery shells in terms of power, speed, and superior performance.
Today, many missiles fly at speeds of up to 400 kilometers per hour and are extremely accurate at long-range targets.
To cope with the complex and ever-changing modern military situation, it is necessary to study not only the performance and launch speed of missiles, but also the in-depth study of hypersonic flight. Only in this way will we be able to develop missiles that are far greater than the speed of sound, thereby enhancing our national defense capabilities and creating a deterrent effect in the international arena.
At the same time, we need to be clear that missiles and anti-missile systems are interrelated. If missiles are invented, anti-missile systems will inevitably follow, which is a very common phenomenon in the military.
In order to protect our country from missile attacks, we must develop accurate anti-missile systems. To achieve this, we must apply the "Qian Xuesen ballistic theory" to accurately estimate the missile's flight speed and trajectory, so as to carry out accurate anti-missile attacks.
There seems to be a paradox in this phenomenon: people want their national missiles to fly faster, but they also expect more sophisticated anti-missile systems to respond to the threat. The "pit" that Qian Xuesen planted back then has now been jumped into by scientists from all over the world, and it seems to be providing a direction for China's scientific and military research.
What is amazing is that although Qian Xuesen is an aerodynamicist, he has made great achievements in the field of supersonic missiles and aerial vehicles, as well as aerospace, and is undoubtedly an outstanding "strategic scientist".
At that time, Qian Xuesen relied on extraordinary perseverance and determination to overcome many difficulties and return to the motherland. He was bent on delving into the topic of hypersonic flight, but the situation in the country was not stable, and there was a more urgent task than research - the creation of an atomic bomb.
Therefore, the study of "supersonic" was delayed for twenty-three years. It was not until the 80s, when Qian Xuesen successfully completed the research and development of "two bombs and one satellite", that he focused his attention on the field of hypersonic flight and actively invested in the research of military aviation.
With his support, the rocket industry in our country has achieved amazing development. In the process of rocket development and manufacturing, the theory of hypersonic flight has played a huge role, enabling China's rockets to fly higher and farther.
At the same time, this theory is also applied to China's Dongfeng missile, which is a missile independently developed by China, including short-range, medium-range and intercontinental missile series. It can be said that in the field of missiles, scientists have given full play to Qian Xuesen's "supersonic" theory and made it play its greatest value.
In actual operation, China's Dongfeng missile, with its astonishing speed, precise strikes, and unpredictable trajectory, has made it an important force in warfare. This advantage allows the Dongfeng missile to gain the upper hand even in the face of specialized anti-missile systems.
Although China has successfully applied the concept of supersonic to the aerospace and military fields, it is still only scratching the surface of this field, and deeper theories still need to be explored.
However, we have reason to believe that in the near future, our country will fully grasp the concept of supersonic and apply it more deeply to the defense military.
