METHOD OF PROTECTING OF AIRCRAFT MID-FLIGHT ENGINES AGAINST TURBULENT FOREIGN OBJECT INGESTION Russian patent published in 2013 - IPC B64D33/02 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering. Proposed method consists in starting from lineup, accelerating at low power plant rpm, continuation of starting takeoff run at power plant standard acceleration capability from the end of lower rpm mode to maximum rpm mode and continuation of takeoff run at maximum rpm. First, aircraft bench tests are carried out and aircraft model is analysed in wind tunnel. To optimize takeoff kinematic parameters, mathematical simulation of aircraft takeoff run dynamics and variation of power plant operating conditions is performed at complex mathematical model "engine+aircraft". To takeoff with extra thrust at optimum kinematic parameters, pilot is informed on aircraft engine rotor design rpm corresponding to lower rpm and related time and path of running at said lower rpm which ensure minimum probability of turbulent ingestion of foreign objects.

EFFECT: minimised probability of ingestion of foreign objects.
