METHOD OF REDUCING AIRCRAFT RADAR VISIBILITY, EQUIPPED WITH GAS TURBINE ENGINES Russian patent published in 2018 - IPC H01J1/00 B64C1/36 

FIELD: radio engineering, communication.

SUBSTANCE: method of reducing the aircraft radar visibility, equipped with gas turbine engines is that a plasma formation absorbing the probing radiation of the radar station is created in front of the engine elements contributing a great deal to the power of the reflected radiation. Plasma formation is created by means of a high-voltage corona avalanche streamer discharge, and the probing radiation of the radar station is intercepted and directed to the plasma formation zone by means of an adjustable waveguide in the engine with a variable cross-section decreasing from the amount providing a cover from the radiation of the engine element contributing greatly to the reflected radiation power of the radar station to the value equal to the cross section of the plasma formation zone, the waveguide walls are made of a conductive mesh, providing a gas flow passage.

EFFECT: ensuring the possibility of reducing the region of plasma formation, while maintaining the effectiveness of radar protection, reducing the region of plasma formation will reduce the dimensions and weight of the device creating the plasma and reduce the energy consumed by it.
