本文从低空飞航式导弹的特殊布局和结构安排出发,考虑到开伞过程的特殊要求和回收的实际需要,建立了相应的数学模型,研究了二次爬高,双组元燃料放泄,开伞过程等问题。通过大量弹道计算,就如何满足开伞条件;选择伞的特征阻力;计算和选定有关指令;弹道特点及如何实现所需指令提出了看法,并在飞机投放模型弹回收的开伞实验飞行中获得了成功,而二级推力爬高的研究结果已在三年前的飞行实验中获得成功,证实了基于计算研究所得结论。
In this paper, starting from the special layout and structure of low-altitude flight-borne missiles, taking into account the special requirements of the parachute process and the actual needs of recovery, the corresponding mathematical model was established and the secondary creeping height, Parachute process and other issues. Through a large number of ballistic calculations, how to meet the requirements of the parachute, the characteristic resistance of the parachute, the calculation and selection of the relevant instructions, the characteristics of the trajectory and how to achieve the required instructions were proposed and used in the parachute experiment flight recovered by the aircraft model Was successful, and the results of the second-level thrust climb have been successful in flight experiments three years ago, confirming the conclusions based on the computational studies.
