易弯曲拖拉绳索空间形状和张力分布分析

Analysis on Space Shape and Tension Distribution of Towed Flexible Cables

本文给出了被飞机拖拉着飞行的易弯曲的绳索在三维空间的形状和张力分布的理论分析方法。分析中考虑了作用在绳索上的重力、空气动力以及上下两个飞行器对绳索形状和张力分布的影响。也考虑了飞机作加速运动时各个方向加速度的影响。本文提供的分析方法是解决“飞机-拖索-拖靶”动力学系统运动问题的基础工具之一。

This paper comprises a study of the theoretical analytical method by which to calculate the shape and tension distribution of the flexible flying cable towed by aircraft. The study takes account of the influences of gravity and aerodynamic force on the lowed cable and on its shape and tension distribution. Also taken into account is the influence of the acceleration when the aircraft is accelerating in different directions. The analytical method suggested in this paper is one of the essential tools by which to study the problems with respect to the movement of the aircraft-towed cable-target dynamic system.
