摘 要:為研究發(fā)射藥內彈道性能隨著(zhù)儲存時(shí)間增長(cháng)的變化,通過(guò)高溫加速老化試驗的方法模擬得到不同儲存時(shí)間的發(fā)射藥。利用密閉爆發(fā)器裝置對不同老化時(shí)間下的11/7發(fā)射藥、7/14發(fā)射藥的內彈道參數進(jìn)行測試,得到發(fā)射藥燃燒過(guò)程中壓強隨時(shí)間以及燃速隨壓強的變化過(guò)程。試驗結果表明隨著(zhù)老化時(shí)間的增長(cháng),發(fā)射藥的最大膛壓越高;發(fā)射藥老化時(shí)間越長(cháng),在相同的壓強下發(fā)射藥燃速越大。但是不同老化時(shí)間發(fā)射藥的最大膛壓值及燃燒值相差幅度不大。

Abstract: In order to study the interior ballistics properties changing of propellants as the storage time goes, the propellants are attained by high temperature accelerated ageing tests. Interior ballistics properties of 11/7 and 7/14 propellants are tested by manometric bomb under different storage time, the pressure via time and burning rate via pressure changing procedure are got. The test results show that the value of max pressure and burning rating under same pressure increase as the storing times goes, but increment amplitude is small.
