摘　　要：柔翼飞行器广泛应用于军事物资空投与装备回收等领域,为深入研究柔翼飞行器的飞行性能,基于Kirchhoff动量方程,考虑附加质量、展向环量、耦合因素的影响,建立8-dof柔翼飞行器的动力学方程,在此基础上,针对襟翼偏转、动力推进、风场干扰等因素对飞行器的飞行性能进行分析,并与空投试验进行对比。结果表明,所建模型的仿真数据与空投数据接近,较好地描述了柔翼飞行器在雀降、转向、爬升、风扰等阶段的飞行性能,为军事保障中柔翼飞行器精确投放提供参考。For the great performance of gliding and controllability,the flexible aircraft widely used in the fields of material transportation and equipment recovery.In order to deeply research the flight performance of flexible aircraft,this paper built 8-dof dynamic model of flexible aircraft based on Kirchhoff Equation,which considering the influence of added mass,spreading circulation and coupling factor.On this basis,the model was simulated to analyse the performance of flexible aircraft from the factors of flap deflection,driving force and wind field interference,and compared with airdrop test data.Research indicates that the simulation data is close to the airdrop data,and the flexible aircraft model better describes the position,attitude and velocity of flexible aircraft in the stage of landing,steering,climb and wind disturbance,which provides reference for the accurate launch of flexible aircraft in military guarantee field.
