主 题:compound helicopter wing propeller flight performance lift distribution thrust distribution
摘 要:The performance of slowed-rotor compound aircraft,particularly at high-speed flight condition,is *** forward flight performance calculation model of the composite helicopter is established,and the appropriate wing and propeller parameters are *** predicted performance of isolated propeller,wing and rotor combination is *** kinds of tip speed and a range of load share setting are *** bearing 80%of the thrust with wing sharing lift is found to be the best condition to have better performance and the maximum L/D for maximum forward *** rotor,propeller,and wing performance are examined for sea level,1000 m,and 2000 m cruise ***,propeller,and wing power are found to be largely from profile drag,except at low speed where the wing is near *** elevation offloads lift from the rotor to the wing,dropping the total power required and increasing the maximum speed limit over 400 km/h.
