摘　　要：以某60 kg级复合翼飞行器的旋翼和推进螺旋桨为对象,以片条理论和动量理论为依据,循环求解桨前速度增量,结合地面试验数据修正螺旋桨力学模型,得到螺旋桨的力学性能。模型计算结果显示,推力计算偏差小于5%,功率计算偏差小于10%。由此计算螺旋桨在一定来流下的推力与转速和控制参数的特性曲线,建立螺旋桨与控制参量之间的关系,以支持复合翼飞行器动力模型研究。In this study,we build a model for the rotors and propellers of 60 kg combined wing aircraft based on the strip and momentum theory,and circularly calculated the increment of the upcoming flow as an intermediate variable to precisely determine the propellers’performance.By comparing the obtained results with the experimental data,we corrected the model and calculated the mechanical performance of the propeller.Result showed that the model could evaluate the thrust and shaft power with a bias of less than 5%and less than 10%,respectively.Using this method,we drew the MAP curves representing the mechanical performance as the essential parameters in the power model and built a bridge between mechanical performance and controlling model.The results can support the study of mechanical modelling of combined wing aircraft.
