In China, presented a ceramic composite for hypersonic aircraft. It will withstand a temperature of 3 thousand degrees Celsius!

A new composite material based on ceramics and refractory materials will be able to withstand heat

temperatures up to 3 thousand degrees Celsius.Other technical details of the future alloy have not yet been disclosed. It is only known that if the airframe is sheathed with such material, the aircraft will be able to fly at speeds of up to Mach 20 - more than 20 thousand km/h.

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 infield of development of hypersonic aircraft. Recently, Chinese engineers from the Chengdu Aviation Research and Design Institute conducted the first stage of bench testing of the TBCC combined hypersonic engine - it can be used for hypersonic aircraft. 

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.
