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

FIELD: engines and pumps.

SUBSTANCE: invention relates to power engineering. the jet turbine engine (JTE) is double-flow, two-shaft one, it contains minimum eight modules including high and low pressure compressors separated by an intermediate housing, a main combustion chamber, an air-to-air heat exchanger, high and low pressure turbines, a mixer, a front device, an afterburner and a rotary jet nozzle comprising a rotary device and an adjustable jet nozzle, attached to the rotary device with a possibility of performance together with a mobile element of the latter of rotations for change of the thrust vector direction. The engine is tested on the bench which is fitted with an inlet aerodynamic device with a remotely-controlled sliding intertseptor. In case of necessity the tests are repeated with the set of modes corresponding to the modes of real work of turbojets in flight conditions according to regulations.

EFFECT: invention allows to provide increase of extensionality and reliability of statically reliable data on allowable boundaries of frequency modes of rotor rotation with ensuring of gas-dynamic stability of engines with simultaneous simplification of technology and reduction of labour and power consumption of test process.
