摘要
声呐浮标是航空反潜最有效的手段之一,为了充分认识声呐浮标高空投放条件,高效率地布放声呐浮标,开展声呐浮标空中运动轨迹研究。描述了声呐浮标空投过程,对模型进行简化假设,建立坐标系;利用飞行力学的相关知识详细地分析声呐浮标自由飞行、开伞变速、稳定下落等3个运动阶段,建立运动方程;举例进行数值仿真,绘制俯仰角、弹道角、速度、运动轨迹等参数的变化曲线;声呐浮标会在一定的时间内实现稳定下落,最大水平位移不变,落水区域可控,竖直位移随时间匀速增加。可以在本文研究基础上进一步开展工作,增加更多随机条件,生成声呐浮标的空投射表。
Sonobuoy is one of the most effective means of aerial anti-submarine.In order to fully understand the conditions of high air-dropped sonobuoy and sonobuoy can be efficiently placed,the aerial motion trail of sonobuoy is studied.The air-dropped process of sonobuoy is described,the model is simplified and the coordinate system is established.Based on the theory of flight dynamics,the three movement stages of sonobuoy are analyzed in detail,such as free flight,variable speed and stable falling.Establish equations of motion.For example numerical simulation,the variable curves of pitch angle,trajectory angle,speed,motion trail and other parameters are drawn.Sonobuoy will achieve a stable fall in a certain time,the maximum horizontal displacement remains unchanged,the falling area is controllable,and the vertical displacement increases uniformly with time.On the basis of the research in this paper,more random conditions can be added to generate the air-dropped firing table of sonobuoy.
