Tupolev PJSC recently received a patent for a promising hypersonic aircraft, which, according to the patent documentation, has a combined annual power plant, including three aircraft engines at once – this is a prime TRD powered by aviation kerosene of the OM brand of cryogenic fuel, which can be used as LNG or liquefied. hydrogen.
Since it is used by isolating cryogenic gas in the same way, the installation should provide a solution to the problems of heating the plane from friction of its surfaces and the incoming air flow during supersonic flights, and kerosene turbojet engines are apparently used in other flight modes.
It is very important that the support is very low. The sound requires serious cooling of the airframe, for which I act What are cryopolished tanks specifically designed for special purposes? intensive gasification.
This endothermic process, in which the temperature is covered, is that we will carry out the construction of the aircraft and elements of the same engine, after which the cryogenic fuel, when heated, takes on a gaseous form and is used in the combustion chamber and it. afterburner to increase traction.
