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

    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.
    Keywords: propellant; high temperature accelerated ageing; interior ballistics property; storage time
