  • The regulation of turbocharger exhaust valve was studied in cruising condition by analysis of engine propeller's power characteristic.The economy of aircraft operation was also predicted.Cruising condition of constant 180km/s was researched at 4000 meters altitude,the target pressure of air box could be reached by adjusting exhaust valve,and the propeller pitch was determined by propeller characteristic map.The results show that compressor matched with turbocharger is working within 68%~76% high efficiency area by regulating propeller pitch and turbocharger exhaust valve at constant speed of the airplane.
