Research on a transient temperature measuring device with blind hole for a large caliber gun

摘要：

　　During gun launching, the propellant gas in the tube is characterized by strong transient, high temperature, and high pressure.The time scale of the interior ballistic process is very small, in milliseconds, and there is heavy noise disturbance during the launch process.Therefore, the temperature on the inner wall surface of the gun cannot be measured directly with the sensor.This paper aims to ensure thermal safety of the gun and conduct inverse problem research on the inner surface temperature of the tube through the local point temperature based on the heat transfer inversion theory.The temperature distribution of the point at a certain thickness range can be got by the dynamic temperature measurement device.Then the real-time temperature distribution of the inner wall of the tube is obtained through the inversion program, and the thermal safety of the tube is evaluated accordingly.
