FIELD: mechanical engineering; gas-turbine engines.
SUBSTANCE: proposed power plant for starting gas-turbine engine has gas generator with compressed air takeoff and exhaust duct connected with air turbine of starting device and air conditioning system. Power plant is furnished with compressed air heater made in form of heat exchanger arranged in exhaust duct of gas generator and connected by its input with compressed air takeoff of gas generator, and by output, with air turbine of starting device, and change-over connected by its input with compressed air takeoff of gas generator and by its outputs, with compressed air heater and with air conditioning system.
EFFECT: improved reliability and facilitated starting of gas-turbine engine.
