A Method for Estimating Propeller Tension Using General Propeller Characteristic

本文利用有限螺旋桨风洞试验数据及耦合系数法对通用的螺旋桨部件进行耦合,耦合系数通过粒子群算法优化获得。分别使用风洞特性以及耦合后的通用特性对不同高度发动机各状态的拉力进行仿真,结果表明,基于粒子群算法的耦合系数法具有一定的精度。

The limited number of propeller wind tunnel test data and the coupling coefficient method are used to couple the general propeller characteristic,and the coupling coefficient is obtained through particle swarm algorithm.The wind tunnel test data and the coupled general propeller characteristic are used to simulate the propeller tension at different heights and engine states.The results show that the coupling coefficient method based on particle swarm algorithm has certain accuracy.
