The Unmanned Underwater Vehicles (UUV) designed for the detection and neutralization of naval mines are characterized by their high requirements regarding the reduction of the signatures of a vessel (thermal, acoustic, magnetic, etc.), all of them must be reduced in order not to be detected by the mines during the mission. This research work focuses on the reduction of the thermal signature transmitted by the UUV hull, where the use of phase change materials (PCM) is proposed as thermal insulation, placing it between the internal heat source of the UUV and the pressure hull, with the aim of drastically increasing the time in which the external face of the hull of the UUV is within a range of 3 °C and 5 °C temperature increase, allowing it to perform its mission without being detected by the thermal sensors of current naval mines. The simulation will be carried out using the Network Simulation Method for the resolution of the governing equations, which will allow the optimization of the necessary insulation thickness according to the required mission profile. In addition, it is proposed an expression that relates the PCM thickness and the time needed to reach a certain temperature increase.

设计用于探测和中和海军水雷的无人水下航行器（UUV）的特点是对减少船只特征（热，声，磁等）的要求很高，必须按顺序减少所有这些在执行任务期间不会被地雷检测到。这项研究工作的重点是减少UUV船体传递的热信号，在这种情况下，建议使用相变材料（PCM）作为隔热材料，将其放置在UUV的内部热源和压力船体之间，并通过目的是大幅增加UUV船体外表面在3°C和5°C温度范围内的时间，从而使其能够执行任务，而不会被当前海军矿山的热传感器检测到。仿真将使用网络仿真方法进行，以求解控制方程式，这将允许根据所需的任务概况优化必要的绝缘厚度。此外，提出了一种表达式，该表达式将PCM的厚度和达到一定温度升高所需的时间联系起来。
