摘要:

分析总结了水下航行器的自身结构、环境和任务的特点以及复杂海洋环境对航行器的安全造成的威胁。从海流干扰、海水透明度、跃层及海洋内波等水文环境要素的形成原理及其对航行器的影响等方面,分别总结了各主要海洋环境因素对水下航行器航行状态的有利与不利影响,同时避免各要素直接或间接造成的各种不利影响的方法,结合航行器自身的结构特点和任务需求,充分利用海洋环境因素,可以使航行器在安全性、经济性、操纵性以及作战能力等方面有较大的增强和改善。提出根据不同任务对海洋环境因素做威胁权值评估,并根据其威胁度,在自主航路规划过程中适当修订航线。通过仿真验证了该方法对航路准确定和安全性的提高。

Abstract:

This paper analyzes the characteristics of underwater vehicle’s configuration, environment and missions, and the menace of complex ocean environment. The advantage and disadvantage of the main ocean environmental factors to the navigation states of underwater vehicles, as well as the methods for avoiding all kinds of disadvantageous influences caused by all kinds of factors are concluded. The main areas consist of current disturbance, seawater transparency, thermal layer and ocean internal wave. The vehicle enhancement and improvement in the performance of security, economy, maneuverability and operational performance can occur by combining the configuration characteristic of underwater vehicle and the mission requirements. This paper proposes to assess the threat weight of the ocean environmental factors according to different missions based on the degree of threat and underwater vehicle modified route in its autonomous sailing. Finally, the simulation proved that the method increases the accuracy and safety of its route.
