摘　　要：水下枪械是用于水下作战部队的新枪种,水下枪械的膛壁温度测量,对比空气和水下发射时温度的变化对水下内弹道模型的符合参数取值有着重要的意义,同时枪管膛壁温度分布的变化对研究膛壁的烧蚀和提高身管寿命等都有帮助。为测量水下发射装置在发射过程中壁温的瞬态变化,设计了PtR t10-Pt微热电偶,进行测试系统设计,对测试信号用小波分析的方法处理,得到了水下枪械不同固定点壁温的变化规律,为研究水下枪械发射过程温度变化及其他研究奠定了基础。Underwater gun is a new kind of arm for underwater combat army. Temperature measurements of its chamber wall and comparing the temperature change launching in the air and underwater have an important meaning for the ballistic model parameters choosing. At the same time, the temperature distribution of chamber wall is helpful for studing chamber burning and prolonging bore life. In order to measure transient wall temperature changes of underwater gun in the launch process, PtRtlO-Pt micro-thermocouple and test system are desinged. Wavelet analysis method is used to process test signals. Temperature variation rule of underwater gun in different fix up point is got for the study of the launch process of underwater gun firing and it is the foundation for other studies.
