包覆药装药低温感效应研究

Study on the Low Temperature Sensitivity of Coated Propellant Charge

该文提出了燃面温度系数的概念，研究了包覆药装药的低温感原理，采用中止燃烧试验，测试了包覆药９Ｂ、１１Ｂ的燃面温度系数特征值，研究了燃面温度系数与弹道温度系数的关系。

In this paper,the concept of buring surface temperature coefficient(BSTC)of explosive charge is introduced and the mechanism of the low temperature sensitivity ofcoated propellants charge is studied. With a controllable semiclosed bomb the BSTC functional values of the coated propellants-9B and 11B are measured.The relationship betweenBSTC and ballistics temperature coefficients are discussed。
