Zhuangao Xinhua (Xinhua military commentator Zheng Wenhao) May 12, China’s first National Air Plasma Dynamics Laboratory at the Air Force Engineering University was established. For most people, this macro-neutral plasma ionized gas away from their lives is too far away. Even the love of military users, many in this area is only superficial understanding. The relationship between plasma and military aviation, the most widely spread is the so-called “Russian fighters to use plasma stealth” the comments.
said “plasma stealth”, it is necessary that human manned space flight. In a second spacecraft, the shuttle returned to Earth in the process, because of their dramatic and atmospheric friction, the spacecraft surface of the plasma layer, the electromagnetic shield. Many Chinese people will remember the times when the Shenzhou spacecraft returned to Earth for some time and the ground will temporarily break contact, that is a reflection of this phenomenon. Of course, this phenomenon has long been the attention of military and technical personnel, is the potential of this plasma to achieve the electromagnetic shielding of active stealth combat aircraft. However, vision does not mean that engineering practice, in fact, to achieve stealth through the plasma from the engineering point of view it is difficult to achieve. Tens of meters long because I wanted to achieve coverage of combat aircraft, plasma layer, or at the expense of the aircraft’s aerodynamic shape, or the power of aircraft and fuel made difficult to achieve the requirements.
now study the plasma, can be determined basically. Heat generated by atmospheric friction that the plasma is not used in stealth aircraft. Even in Russia, now there is no there is no conclusive evidence to prove useful plasma stealth aircraft technology. The only widely held in the technology sector, there are rumors that the U.S. B-2 bomber using a number of steady-state power or the microwave generated by the cold plasma to achieve stealth. This rumor, and the U.S. public B-2 flying wing and the use of stealth coatings to achieve very different argument. As the B-2 bombers involved in the core of U.S. military secrets, saying only plasma stealth is a doubt.
addition to plasma stealth, then the plasma and military aviation meeting point where is it?
we might look at the original piece of news. Not difficult to find, the lab’s full name is “Air National Key Laboratory of Plasma Dynamics”, there are dynamics that keyword. The news also mentioned: “The lab is set up to promote the development of air power in China in the field of theoretical and technological innovation to achieve an important measure to address the constraints and the development of aviation equipment and air force generated bottleneck study provides an important platform … “The answer is very obvious, plasma research and the” air power “which restricts the development of China’s aviation equipment and air force generated bottleneck has a direct relationship.
some public information that the plasma in the air force, and can effectively improve the combustion stability and combustion efficiency, which greatly improve the aero-engine compressor pressure ratio rises after work stability, thereby achieve 10 or even higher thrust-weight ratio turbofan engine production; in aircraft aerodynamics, the plasma can reduce aircraft drag, increase lift, improve the aircraft’s stall angle of attack and maneuverability.
such as aircraft engines, the fan, air compressor is the core component of turbofan engines. Improve aviation turbofan engine thrust-weight ratio, can only increase the compressor pressure ratio, and the attendant problem is the compressor exit area sharply reduced, severely reduced efficiency. Compressor through a specific position in the plasma excitation device layout, the engine will improve the flow of the gas effect.
no doubt that the plasma kinetic studies on a global scale is a very advanced field. So that the information in the public, only know the flow of plasma on the air will have an effect, but its role in the mechanism is unclear. So some of the advanced air force abroad, such as F-119, F-135 engine, is using the plasma technology, is a mystery. However, the establishment of the China National Key Laboratory of Plasma, shows China’s air force, aircraft aerodynamic research, has entered the forefront of the field. As China’s research in plasma dynamics deepening of China in the development of thrust-weight ratio of more than 10 advanced aircraft engine technology accumulation, will be more profound, so as advanced aircraft, space vehicles, the development of large military transport aircraft to lay a solid basis.
