摘要

摘要: 空投鱼雷和火箭助飞鱼雷雷伞系统中, 降落伞的作用力简化为作用在雷尾且与气流方向一致的力, 而基于此建立起来的雷伞系统数学模型很难对雷伞系统的锥摆等做出准确的分析。为了解决这一问题, 该文从空气动力学的基本原理出发, 综合应用降落伞动力学、多体动力学的理论和分析方法, 利用牛顿和Kirchhoff方程建立了雷伞系统稳定下降阶段的5自由度动力学模型, 并进行了仿真分析, 仿真结果表明, 该系统具有较好的一致收敛和稳定性, 本文方法为开展降落伞工程设计提供理论参考。

Abstract: In the conventional torpedo-parachute system, the effect of parachute is simplified to a force acting on torpedo tail and being along airflow direction, which leads to inaccuracy in numerical analysis of coning motion. According to the fundamental principles of aerodynamics, we establish a five-degree-of-freedom dynamic model of terminal descent of torpedo-parachute system based on the Newton and Kirchhoff formulas by applying the principles and analytical methods of parachute dynamics and multi-body dynamics. Simulation result demonstrates the reliable convergence and stability of the present system. This system may be applied to the engineering design of torpedo-parachute system.
