电动飞机在飞行过程中其质量始终保持不变,使得对其进行起飞总质量估算的过程中,在参数的确定方法上与传统的燃油飞机有所不同.首先提出了适用于电动轻型飞机的按任务剖面、按商载和航程估算起飞总质量的方法,并对任务剖面法解的存在性和收敛性进行了分析.然后以某型双座电动轻型飞机为例,应用这两种方法对起飞总质量分别进行了估算,取两者的平均值作为最终起飞总质量的估算值,并对该估算结果的合理性进行了分析.提出的方法为后续电动飞机的研制具有参考价值.%Because the weight of the electric aircraft remains unchanged in the flight,the method of parameters determination is different from the traditional fuel aircraft. First, the estimated method of the mission profile and method of the payload and range were put forward,which were applicable to the electric light aircraft,and the ex-istence and convergence of the solution of the mission profile were analyzed. Then using a two-seat electric light air-craft as an example,the take-off weight was estimated by the two methods,and the two solutions were averaged as the final estimated value of take-off weight. The rationality of the estimated value was analyzed. The approach pres-ented will provide a reference for the development of the future electric aircraft.
