DEVICE AND METHOD FOR PREVENTION OF ICE FORMATION ON ENGINE Russian patent published in 2019 - IPC F02C7/47 B64D15/04 

FIELD: machine building.

SUBSTANCE: disclosed are systems, methods and devices for preventing formation of ice on an engine. Device may include a housing for nozzles connected to an engine compression stage and, in addition, connected to the housing of the leading edge of the engine. Nozzle housing can receive gases from the engine compression stage. Nozzle housing may include a first nozzle, which may be configured to create a first flow configuration and, in addition, may be configured to create a first flow from a first portion of said gases with the leading edge fed into the housing based on the first flow configuration. Nozzle housing may also include a second nozzle, which includes a concentric nozzle comprising a through hole passing through the nozzle housing, configured to create a second flow configuration. Second nozzle may be configured to create a second stream from the second portion of said gases with the leading edge fed into the housing based on the second flow configuration.

EFFECT: improving and ensuring the efficiency of mixing a jet of the second stream, which minimises the thermal load on the materials of the housing of the leading edge and formation of ice.
