METHOD OF CONTROL OF AIRCRAFT POWER PLANT Russian patent published in 2007 - IPC F02C9/42 

FIELD: methods of control of aircraft power plants consisting of two gas-turbine engines in case of loss of thrust by one of them.

SUBSTANCE: proposed method of control of aircraft power plant includes measurement of parameters of thrust of two engines, comparison of these parameters with preset magnitudes required for starting the increased thrust mode, measurement of engine control lever position and comparison of them with preset magnitudes corresponding to takeoff mode of aircraft; in case of failure of one of engines, increased thrust mode of other engine is started. Proposed method includes also additional measurement of aircraft air speed V_a. Which is compared with preset speed and signals I_sl. "slats not retracted" and I_p.b. "parking brake switched off". Increased thrust of intact engine is settled at V_a.> and availability of signals I_sl. and I_p.b.

EFFECT: enhanced safety of flight due to avoidance of prohibitive settling of increased thrust mode at takeoff and ascent of aircraft.
