Research on Problems in Traditional Method Measuring Real-time Temperatures of a Gun or Rocket Charge
The paper researches on problems and error values of traditional method measuring real-time temperatures of a gun or rocket charge. Firstly, four error sources are derived from implication of charge temperature affecting the weapons firing range in interior ballistics and current procedure for the artillery to measure real-time charge temperatures. Secondly, working conditions in battlefield of several typical gun and rocket charges are simulated and their unstable temperature fields are measured. According to defines of each individual error such as measuring point error and total measuring error, the experimental data are arranged and calculated, and then each individual error and total measuring error at every temperature-read time are gotten. Furthermore, the maximum and mean square deviation of the total measuring errors at all temperature-read time are obtained. From the maximum error and mean square deviation data, it is proved that there exist serious problems in the traditional method measuring real-time temperatures of a gun or rocket charge, and that caused measuring error cannot meet accuracy requirements of the modern artillery. Finally, error characteristics and way to research and develop the future device that can accurately measure real-time temperatures of a gun or rocket charge are discussed.
