摘要
通用航空飞机普遍采用了活塞式发动机和螺旋桨作为其动力装置。在飞机设计阶段,螺旋桨的性能计算具有重要的意义。基于片条理论方法,编制了螺旋桨性能计算程序,对某型螺旋桨的性能进行计算与分析,包括:拉力系数随前进比的变化;扭矩系数随前进比的变化;功率系数随前进比的变化;效率随前进比的变化;并与螺旋桨的风洞实验结果进行对比,验证了计算结果的合理性。
General aviation aircraft generally uses the piston engines and propellers as its power plant. The performance calculation of the propeller is of great significance in the phase of the plane design. Based on the standard strip analysis, this paper presents a numerical procedure, and carries on the calculation and a- nalysis of a certain type of propeller performance. It includes, thrust coefficient changes with the advance ratio; torque coefficient changes with the advance ratio; power coefficient changes with the advance ratio; propeller efficiency changes with the advance ratio. Compared with the results of the tunnel test, the paper verifies the rationality of the calculation results.
