摘　　要：采用简化的拖曳系统纵向小扰动运动方程,计算分析了拖缆对拖曳系统中飞行器纵向扰动运动模态的影响.采用未经简化的拖曳系统纵向小扰动运动方程,通过仿真计算的方法,与上述分析方法和计算结果进行了对比.结果表明,相对于独立的飞行器,拖曳系统中飞行器纵向扰动运动的短周期模态特性变差,半衰期延长;长周期模态性质可能改变,由周期模态变为非周期的,甚至是发散的模态.The influences of towline on dynamic stability of vehicles were calculated and analyzed by using the simplified longitudinal small disturbance equation of towing system. The above analysis method and computing results were validated by simulation using the longitudinal small disturbance equation set of the towing system which was not simplified. The results show that the mode characteristics of short period mode of the vehicles in the towing system become worse, and the half-life is prolonged. The mode property of long period mode can be changed from periodic mode to nonperiodic mode or even divergent mode.
