摘　　要：依据轻型电动载人飞行器的运行特点和电池放电的Peukert效应,在对电池有效容量进行局部修正的基础上,提出了一套简便、有效的电动飞行器航程与航时的计算公式,并对中国轻型双座电动飞行器E430的航程与航时性能指标进行了定量评估,计算结果与E430的官方数据吻合良好,证明了所提公式的正确性与有效性。最后,分析了电池容量对电动飞行器航程与航时的影响。结果表明:当电池的额定放电电流大于飞行器所需消耗的电流时,电池系统引起的Peukert效应会增强电动飞行器的飞行性能;若电池重量占飞行器总重的比重一定,仅仅增加电池容量,飞行器的航程与续航时间将会减少。Expressions to estimate the range and endurance for the light electric manned aircraft performance analysis make great significance. If we ignore the influence of the Peukert effect on the effective battery capacity, these estimates will deviate much respectively from their values in the actual situation. We modify the effective battery capacity through applying Peukert effect principle, thus deriving formulas of the range and endurance for the electric vehicle not much deviating respectively from their values in the actual situation. The results show that, when the battery capacity is larger than needed for the current demands, the electric aircraft flight performance will be enhanced due to the Peukert effect caused by the battery system; fuller and more precise preliminary conclusions are given in section 4 of this paper.
