摘要:
该文研究了添加膨化硝酸铵(EAN)对硝胺发射药的燃速性能及力学性能的影响,使用SEM手段观察了断口试样的微观形态。结果表明,EAN颗粒的引入破坏了基体的连续性,产生了大量的内界面,从而增大了低温燃烧时的有效燃面,而高温燃烧时由于EAN特性结构受火药基体的热胀挤压减少了有效燃面,这样使不同温度下的燃速趋于一致,从而导致硝胺发射药温度系数的降低。
Abstract:
T his paper fo cuses o n the ef fect of adding ex panded ammonium nit rate on the combust io n and mechanics of nit ramine propellant , as w ell as the morpho logy of impact fr actured surface o btained by SEM. It show s that due to EAN f il lers, the cont inuity of the base is damag ed and a large number of interface is int roduced, hence increasing the effect iv e bur ning area at low temperature. On the other hand, the ef fect ive burning ar ea at hig h temperature becomes smaller because the special str ucture of EAN is pressed by the pr opellant base w hich is expended when heated. As a result , the burning r ate of propellant at dif ferent temperatur es are inclined to identical , thus low ering the temperature coefficient .
