潜用AUV自航发射弹道建模与仿真

摘要

Using torpedo launch tube for swim-out launch is the best method for submarine to launch an autonomous undersea vehicle(AUV). This study establishes the mathematical trajectory models of the AUV swim-out launch based on the launcher with backend water replenishment. The models include a submodel of internal trajectory of launch tube and a submodel of trajectory at the tube orifice. The feasibility of the AUV swim-out launch out of tube is verified by simulation, and the results show that the speed of a submarine, the launching speed, and the positive or negative buoy-ancy of the AUV are the main factors influencing the AUV swim-out launch. This study may provide a reference for swim-out launch of AUV through torpedo launch tube.%采用鱼雷发射管自航发射自主式水下航行器(AUV)是潜艇发射 AUV 的最理想方式.为研究潜用AUV自航发射技术, 文章基于后端有效补水的发射装置, 建立了AUV自航发射弹道模型, 包括AUV发射管内弹道模型和管口弹道模型, 对AUV自航发射出管的可行性进行了仿真验证.仿真结果表明, 自航发射时艇速、AUV出管速度以及AUV自身正浮力或负浮力是影响AUV自航出管可行性的主要因素.该结果可为采用鱼雷发射管自航发射AUV技术提供参考.
