摘　　要：电动无人机在飞行过程中重量基本不发生变化,采用燃油机任务剖面法难以对电动无人机起飞重量建立准确的估算模型。针对小型电动无人机起飞重量的估算需求,在整合相关研究成果的基础上,将现有与电机最大功率有关的电机、螺旋桨、电调质量估算经验公式均转化为只与飞机功重比、起飞总重有关的估算表达式。通过能量守恒构建了与飞机功重比、飞行时长有关的电池质量系数估算模型。利用最佳翼载荷等选取方法确定翼载荷和功重比。最终推导了一种基于不同飞行阶段的功重比、飞行时长的快速估算电动手掷无人机起飞重量的迭代方法。以某电动手掷无人机设计参数作为算例进行估算并与现有同量级电动无人机参数比较,验证了所提估算方法的有效性。The weight of electric-powered UAV basically does not change during the entire flight.The previously used fuel aircraft mission profile estimation method makes it difficult to develop an accurate estimation model for the take-off weight of electric-powered UAV.Aiming at the estimation requirement of the take-off weight of electric-powered Mini-UAV,based on the integration of related research results,transform the existing empirical formulas estimating the mass of motor,propeller and electronic speed controller mass related to the maximum power of the motor into expressions for estimating their mass related to power-to-weight ratio and take-off weight of the aircraft.A model for the estimation of battery mass factor related to the aircraft’s power-to-weight ratio and flight duration has been constructed through energy conservation.Best selection method of the wing load and other methods are used to determine the wing load of the aircraft,which is then used to determine the power-to-weight ratio.An iterative method to quickly estimate the take-off weight of hand-launched electric-powered Mini-UAV based on the power-to-weight ratio and flight duration of different flight phases is finally derived.The designed parameters of a certain hand-launched electric-powered Mini-UAV are used for estimating take-off weight as an example and compared with the parameters of existing electric-powered UAV of the same magnitude to verify the validity of the proposed estimation method.
