摘　　要：为了准确估计电动直升机各系统质量,研究了国内外传统直升机系统的质量估计模型,总结了一部分传统直升机系统质量预估方法,发现其对于超轻型单旋翼电动载人直升机(以下简称“电动直升机”)系统质量估计结果存在较大误差,并分析了误差原因。提出一种基于多元线性回归法的超轻型电动直升机的质量预估模型。使用该模型对某型电动直升机的各系统质量数据进行验证,并将修正系数引入电动直升机系统质量预估模型中,以减少预估误差,最终证明修正后的模型具有较高的可靠性和准确性。In order to estimate the mass of each system accurately,the mass estimation models of traditional helicopter systems at home and abroad was researched,and summarized some traditional helicopter system weight estimation methods.The study finds that there is a large error in the mass estimation results of ultra-light single rotor electric manned helicopter systems,and analyzes the possible reasons for the error.A mass estimation model of an ultra-light single rotor electric manned helicopter based on a multiple linear regression method were presented.The model is used to verify the mass of each system of the electric helicopter,and the correction coefficient is introduced into the system mass estimation model of the electric helicopter to reduce the estimation error,and finally the revised model has high reliability and accuracy.
