Abstract

The paper considers the high-temperature materials currently developed for protection from external influences of radio engineering systems installed on modern aircraft, the flight speed of which is many times higher than the speed of sound. The use of parts made from the considered composite materials ensures an increase in the operating temperatures of aircraft structural elements while protecting antenna systems from the effects of the aerodynamic environment, which improves the accuracy of targeting. It is concluded that the development of domestic high-temperature composite radio-transparent materials based on high-temperature matrices made of silica filaments impregnated with a phthalonitrile binder is promising.
