New composite material based on ceramics and refractory materials will be able to withstand heat
Cladding is one of the main problems in the designmodern hypersonic aircraft. Due to the high speed, the material of the aircraft must withstand extreme temperatures, including from a film of plasma that forms at high speeds on the surface.
China is one of the most developed countries inareas of development of hypersonic aircraft. Recently, Chinese engineers from the Research and Design Institute of Aviation in Chengdu conducted the first stage of bench tests of the combined TBCC hypersonic engine - it can be used for hypersonic flying technology.
Recently, General Electric presented a prototype of a rotary detonation engine that can accelerate aircraft to hypersonic speeds.
Besides General Electric, engine developmentfor hypersonic flights, several other companies are involved, including Aerojet Rocketdyne and NASA. However, it is not yet known when such aircraft will actually appear on the wide market.
To date, many aviation developerstried to create hypersonic aircraft, using various forms and experimenting with streamlined. The most striking example is the Concorde supersonic passenger liner, flying at a speed of up to 1.8 thousand km / h. However, the use of supersonic aircraft was too expensive for airlines.
