【摘要】 针对复合式高速直升机的特定飞行状态需求，对配套研制的推力螺旋桨开展气动特性风洞试验研究，获取了螺旋桨在直升机悬停状态、低速前飞状态、过渡前飞状态以及高速前飞状态的气动载荷、功率需求及效率。试验结果表明，随着前飞速度的增加，螺旋桨的拉力、扭矩及需用功率逐渐减小，螺旋桨效率逐渐增加，且在高速飞行时，螺旋桨效率基本不随飞行速度而变化。更多还原

【Abstract】 According to the typical flight state requirements of compound high-speed helicopter, the aerodynamic characteristics of the thrust propeller were studied by wind tunnel test and the aerodynamic load, power requirements and efficiency of the propeller were obtained in hover, low speed forward flight, transition flight, high speed forward flight. The results showed that with the increase of forward flight speed, the pull coefficient, torque coefficient and required power of the propeller decreased gradually, and in high speed flight status, the propeller efficiency was basically unchanged with the flight speed.更多还原
