摘　　要：针对船用高温气体温度测试快速响应的要求,研制了高温气体热电偶温度传感器,并对该高温热电偶温度传感器的响应特性进行了测试。利用测试得到了高温气体温度传感器响应特性,基于射流冲击理论和高温热电偶的温度梯度动态特性,提出了装载舱内气垫船位置判定算法。搭建了由气源、加热器、喷口和移动式装载舱组成的试验台架,进行了高温气体条件下的热电偶温度快速响应修正算法的验证以及喷口热气100℃~200℃时不同移动速度条件下装载舱内气垫船位置判定算法验证试验。结果表明,基于射流冲击理论和高温热电偶温度梯度的动态特性判断装载舱气垫船位置的算法具有一定可行性,对装载舱环境监控设计具有一定指导意义。Aiming at the requirement of rapid response of marine high temperature gas temperature test, a new high temperature gas thermocouple temperature sensor is developed and the response characteristics of the high temperature thermocouple temperature sensor are tested. Based on the response characteristics of the high temperature gas temperature sensor and the jet impingement theory, the dynamic characteristics of the temperature gradient of the high temperature thermocouple are used to propose the position determination algorithm of the hovercraft in the loading compartment. A test rig consisting of gas source, heater, spout and mobile loading compartment is built, the thermocouple temperature correction algorithm are verified at high temperature. The position judgment test of the loading compartment is conducted at 100 and 200 with different m ℃℃ oving speeds. The results show that the algorithm based on the dynamic characteristics of the high temperature thermocouple temperature gradient to determine the position of the hovercraft is of certain feasibility, and has certain guiding significance for the docking environment monitoring design.
