Innovation for war, high -speed fly

Xinhua News Agency, Changsha, August 11th: Innovation is a war, flying at high speed -Yi Shihe, a professor at the School of Ephyo and Sky Sciences of the University of Defense

I arrived at the office before 8 o'clock in the morning on working days, and left at the middle of the night; the business travel always booked an early flight.

"Hurry up! Faster!" It seemed to have a drum point in my heart. For more than 30 years, Yi Shihe, a professor at the School of Ephyo and Sky Sciences at the University of Defense Sciences, flew all the way, chasing, and transcendence in high -speed flight annemine optical innovation research. Explaining in almost blank areas, after countless failures, come from scratch after many failures, and finally made our army accurately strike new theory and technical support.

In 1991, the Gulf War broke out, and the powerful power of high -tech weapons shocked the world, and also made Yi Shihe, who was about to graduate from graduate students, fell into contemplation. "When can our country have more advanced weapons and equipment?" Yi Shihe painted a question mark in his heart and laid a seed.

In order to find the answer, he was born in physics and decided to join the army. Since teaching at the University of Defense Technology, he has devoted himself to basic research on high -speed aircraft.

"It is difficult to say if this research field can be achieved." Many people around him reminded him that Ke Shihe still pierced in.

The high -speed aircraft is fast and the temperature is high and the temperature is high when flying. "Invisible and unable to find it". The traditional measurement method is powerless. The development of a new generation of high -speed aircraft faces many challenges.

"To study the problem of cracking a new generation of high -speed aircraft, we must first be able to measure the flow field around the aircraft and clarify its mechanism." Yi Shihe determined to break through here. If there is no information to refer to, then think about and innovate yourself.

Yi Shihe kept studying and pondering, and new ideas continued to emerge. However, a problem often solves a problem and new problems occur. As if stepped into the darkness, I couldn't see the light, but I couldn't find the way, but Yi Shihe never gave up. He was like a high -speed aircraft in his dream, sprinting towards the target tirelessly.

After thousands of experiments, it took several years, and Yi Shihe and the leading team finally solved the problem of nanopartal reunion. Subsequently, the research trend was broken and continued to break through, making the high -speed aircraft flow field clearly visible, accurate and measured, and also laid the theoretical basis for the development of a new generation of high -speed aircraft.

Yi Shihe has not stopped here. Next, he focused on the impact accuracy of improving the high -speed aircraft.

To do this study, first of all, a ultra -high -speed camera that can capture high -speed flight flow fields. However, none of the ultra -high -speed cameras that could be found at that time could meet the needs of the laboratory.

Then do it yourself! Yi Shi and the leading team decompose a similar camera, study one by one, and investigate the information and consult relevant professionals if you do not understand.

"Version 1.0", "2.0" and "version 3.0". After half a year, they finally designed a new ultra -high -speed camera, laying the foundation for the next study.

When Yi Shi and continued challenging new difficulties -when the aircraft was flying at a high speed, "high temperature" and "turbulence" made the surface of the aircraft look like a "fireball" on the surface of the aircraft, which caused the imaging detector to be unable to clear the target. The aircraft's "invisible" goal cannot achieve precise blows.

The plan was made round after the test, and the test was done over and over again, but there was still no breakthrough. The research seemed to enter the dead end.

On a storm night, the laboratory was stopped, and Yi Shihe had to temporarily end the work. On the way home, an inspiration flashed. Yi Shihe immediately turned the front, returned to the dark laboratory, and calculated through the microdege of the mobile phone flashlight.

After unremitting efforts, the detailed numerical simulation and experimental test results verified Yi Shihe's ideas. Since then, Yi Shi and the leading team have successfully developed the prototypes of the principle after many years of hard work, and conducted a large number of test tests, which finally resolved this problem.

If you walk the road that others have not walked, only those who have experienced them can truly understand the difficulties. Yi Shi and the whole heart of the high -speed aircraft found on the basic innovation of high -speed aircraft, sitting on the "cold bench". The road to exploration for many years has never been offset. Authorized 35 national invention patents, and innovative results have been widely used in a number of aerospace industry departments and units.

"There are countless scientific research and innovation highlands in front of you need to fly over, 'fighting' has just begun!" Aiming at winning the target, Yi Shi and sprinting all the way. (Participate in writing: Zhang Zhaoxing, Gu Ying)
