摘要
本文研究了“飞机-拖索-拖靶”系统在空中的运动状态和系统各部分之间的相互影响。这一动力学系统在现代武器试验中有着重要作用。 飞机通过拖索拖拉着拖靶一同飞行,拖靶的运动反过来又通过拖索影响飞机运动,为了保持自身的正常飞行,飞机控制系统也要做相应的动作。本文在分析了拖索在空间的形状和张力分布以及拖索的飞行问题的基础上,给出了分析三者自身的运动规律以及它们之间相互影响的方法和飞机控制参数的变化。最后还通过实例进行了具体的分析计算,所得结果可供分析类似问题时参考。
This paper studies the motion of on aircraft-towing-towed target system in air and the mutual influences of these parts on each other. The dynamic system plays on important role in the tests of the modern weapon.The aircraft is flying with a target towed by a towing cable and controrily the target' s motion influence the aircraft flight operation through the towing-cable. To keep the sys-tem itself in normal flight the aircraft control system ought to operate corrspondingly. On the basis of the analysis of the shape in space, the tension distribution, and the flight problem of the towing cable,a method for analyzing the motion law of these parts in the system and their mutual influences are analyzed in the paper. Finally,a typical example is adopted for analysis and calculation. The calculated results may be used as reference for problems of the same kind.
