DEVICE FOR REDUCING TEMPERATURE OF ELEMENTS OF HYPERSONIC APPARATUS Russian patent published in 2022 - IPC B64C1/38 B64G1/58 B64C21/00 

FIELD: aviation.

SUBSTANCE: invention relates to the field of thermal protection of aviation and space-rocket equipment and concerns leading edges and nose part of hypersonic vehicle during flight with hypersonic speeds. Device comprises a hollow element in the form of a shell with a rod installed in its cavity. Hollow element is made either from high-temperature ceramics in the form of hafnium oxide or silicon nitride or from porous silicon nitride with stoichiometric ratio of 4:3, respectively, or from metal. Outer surface of the hollow element is coated with a layer of either aluminum oxide, or zirconium oxide, or silicon nitride, on top of which there is a mirror coating of tungsten or platinum having a positive charge. Inside the hollow element in the nose and tail parts there are mirrors made of ytterbium oxide, which are installed so that infrared radiation from the mirror in the nose part falls on the mirror in the tail part. Rod comprises a pointed core made of tantalum-hafnium carbide and is made with possibility of extension from the nose of the shell and has a positive charge. Non-sharpened part of the rod is made of tungsten.

EFFECT: longer time spent in dense layers of atmosphere with required flight speed, reduced radio visibility.
