METHOD OF OPERATING AIRCRAFT GAS TURBINE ENGINE AND DEVICE THEREFOR Russian patent published in 2016 - IPC H01S3/953 F02K3/02 

FIELD: weapons and ammunition; aviation.

SUBSTANCE: group of inventions relates to combat aircraft, on-board of which a laser weapon is mounted. In method of operating aircraft gas turbine engine including process of air compression in compressors, heat supply in combustion chamber, expansion of gas flow for production of supersonic speed is performed through a binary system consisting of low pressure turbine blades which are made up of Laval nozzles, and installed behind it ring fixed postcritical divergent section of de Laval nozzle. In aircraft gas turbine engine low-pressure turbine working blades are made up of Laval nozzles creating at output of turbine supersonic gas flow with output angle close to 90 degrees. With minimum clearance downstream of low-pressure turbine there is a fixed part, behind which there is a flow-type optical resonator with a mirror system focusing and output laser beam on sighting system.

EFFECT: higher second gas flow leaving optical resonator, which leads to higher laser power and engine thrust, higher reliability.
