METHOD OF TURBOJET OPERATION, TURBOJET THUS OPERATED Russian patent published in 2015 - IPC G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: prior to starting this bypass two-shaft turbojet, engine availability for operation is checked to start, warm up and to accelerate it to specified working conditions. Engine is shut down to execute maintenance inspection and servicing of modules, assemblies and communication systems. At final stage of overhaul, reassemble engine is subjected to bench tests. Test bench is equipped with inlet aerodynamic device, primarily remote control extending interceptor to cross airflow in controlled manner. Said interceptor comprises calibrated scale of its positions with fixed critical point separating the engine by 2-5% from its changeover to surging and to define gas-dynamic stability of engine compressor.

EFFECT: simplified operation, lower labour and power input at tests.
