【摘要】 该文分别采用拖缆的"刚化柔性悬索"和"线性弹簧"模型,建立了拖曳式空中发射重复使用运载器系统的动力学模型,并对拖曳系统在纵向平面内的整个飞行过程,包括起飞、爬升、改平以及平飞,进行了仿真计算,其计算方法是可行的,拖缆采用这两种模型获得的计算结果基本一致,可用于拖曳空中发射重复使用运载器可行性的评价。同时对拖缆采用上述两种模型时,其作用于拖曳飞机和运载器的拉力的大小和方向进行了认真研究,相互印证了这两种模型的可行性。总之,在拖曳系统这样的多体系统中,上述两种拖缆模型的使用是合适的。更多还原

【Abstract】 Taking the towline as "flexible suspended cable with rigidization" and "linear spring", this paper builds the dynamic model of a towed air-launch system, simulates and calculates its full flight course in a longitudinal vertical plane, including take-off, climb, level off and level flight. The simulation results applying the two towline models are almost the same, and can be used to assess the feasibility of towed air-launch Reusable Launch Vehicle(RLV). And the algorithm for simulating the system flight is feasible. In addition, the towline’s forces which act on the towing aircraft and towed vehicle have been researched in detail. The results verify mutually the feasibility of the two models of towline. In a word, it is appropriate that these two models are used in such multibody system.更多还原
