FIELD: aircraft engineering.
SUBSTANCE: proposed method consists in control over actual rotor thrust. Note here that before operation of helicopter collected are initial data on power plant characteristics in compliance with certificates and initial data on rotor thrust at test hovering of helicopter. During the entire term of helicopter operation, collected and fixed are actual data on said thrust, said actual data are be compared by onboard computer with initial values and, in case rotor thrust drops from initial value by preset amount, computer generates the signal for monitor the display the need in correction of engine parameters to values that ensure rotor thrust departure within 0.5% of initial values. Engine operating parameters are adjusted either automatically or manual by servicemen on ground.
EFFECT: higher efficiency of operation.
