【摘要】 研究了两种飞行器模型的着陆特性。模型着陆应用气囊系统衰减着陆冲击载荷。实验模拟着陆的垂直速度为2～6m/s,水平速度0～4m/s,着陆姿态范围-19.5°～+19 5°,测定了飞行器模型的加速度和稳定性。结果表明,峰值加速度随垂直着陆速度的增加而增加,且舱体模型的加速度高于弹体模型的加速度,着陆姿态和水平速度对稳定性有显著的影响。更多还原

【Abstract】 Experimental investigation was made to determine the landing characteristics of two vehicle models using airbag system to alleviate the landing impact load. Acceleration and stability of vehicle models were tested in the range of 2 to 6 m/s vertical velocities,0 to 4 m/s horizontal velocities and - 19.5°～+19.5° landing attitudes.The results show that the peak acceleration increases with landing vertical velocity,and the acceleration of cabin model is lager than the guided missile model.The horizontal velocity and landing attitudes have great effects on the stability of the models.更多还原
