GAS TURBINE ENGINE Russian patent published in 2015 - IPC F02K3/00 G01M15/00 

FIELD: engines and pumps.

SUBSTANCE: gas-turbine engine has double-circuit, two-shaft design, it contains minimum eight modules mounted on modular and unit system including high and low pressure compressors of divided by the intermediate housing, the main combustion chamber, the air-to-air heat exchanger, high and low pressure turbines, a mixer, a front device, an afterburner and an all-rating jet nozzle. The input guiding device of the low pressure compressor is fitted with radial racks which are evenly distributed in the plane of the input section, normal to the engine axis, with the angular frequency (3.0÷4.0) unit/rad. The engine is tested at least according to one of programs - multi-cycle, for gas-dynamic stability or for influence of climatic conditions at the main operational characteristics of the engine.

EFFECT: invention allows to provide traction improvement, improve the reliability of operational characteristics of the gas-turbine engine and representativeness of results of tests for various gas-dynamic situations of engine operation, with simultaneous simplification of technology and reduction of labour and power consumption of test procedures.
