Abstract:
On the basis of analyzing the concept of charge temperature in the field env ironmen,t th is paper d iscusses the unba lances of interna l temperature of charge and environment temperature and the serious ex tents of traditiona l charge temperaturemeasure error. In fac,t the tradit ional charge temperaturemeasure standard dev iations are separately 5. 6~ 6. 1 ℃ and 2. 4~ 3. 0 ℃ for separate loading ammunition and fixed round. From the view of modern w eapon system fire prec ision demands, it is found out that the charge temperature measurem aximum dev iation shou ld be less than 1 ℃ and the standard dev iation less than 0. 7 ℃ through read ing firing table andmak ing demonstration. Therefore, themeasure error o f trad itional charge temperature exceeds 3 to 8 times. A kind o f charge temperature measure equipment is developed w hose measure precision ( standard error) reaches 0. 6℃ .
