摘要/Abstract

摘要： 近年来，各国都在积极探索机载拖曳天线对潜通信系统。天线姿态、受力和天线释放过程的干扰问题是该系统动力学研究的重点。基于此，根据真实机载拖曳天线系统建立瞬态（含释放过程）的双天线动力学分析模型，采用数值计算方法研究了载机、天线及稳定锥参数对天线张力的敏感性及影响规律；选取适当的天线释放方式，从天线张力及释放过程双天线是否干扰的角度对系统安全性进行分析研究。研究结果表明：对长、短天线全过程最大瞬态张力影响较明显的四个参数均为V、C_D、d和L。为尽量减小张力，对于长、短天线均可减小d、L、C_D和V来实现。对于天线释放过程，选择盘旋释放更有利；所研究算例条件下，载机盘旋状态下长短天线释放不产生严重的不利干扰。

Abstract: In recent years, submarine communication with aircraft-towed cables has been studied by many countries, where the configuration and tension of cable and interference during deployment is focused on. Based on this, a simplified transient dynamic model (deployment included) of double cables is built up, and sensibility and influence of variables on cables are studied by numerical computation method; a proper deployment scheme is chosen and safety analysis is conducted in aspect of tension and interference of double cables during deployment. The results show that the four variables with relatively obvious influence on max tension in transient state are V, C_D, d and L for both long and short cables. Tension as small as possible could be attained by reducing V, C_D, d and L of both cables. Deployment during hover is preferred and under circumstance in this essay, severe negative interference between cables doesn't occur.
