FIELD: aircraft industry; gas-turbine engines.
SUBSTANCE: invention can be used in electronic automatic control systems of turboprop power plants. According to proposed method, torque on shaft of free turbine is measured and valve of actual power is determined as product of speed of rotation of free turbine and measured valve of torque, and error signal is formed between preset and actual valves of power, and, according to formed signal, fuel delivery into combustion chamber is changed.
EFFECT: provision of fuel delivery into combustion chamber depending on deviation of engine actual power from preset valve at direct determination of power which improves accuracy of control.
