【摘要】 采用药条燃速仪试验和Φ64mm发动机点火试验,研究了不同含量的快燃物ACP对低、中、高燃速丁羟复合固体推进剂燃烧性能的影响。结果表明,快燃物ACP能明显提高推进剂的燃速,使6.86~15M Pa下推进剂的燃速压强指数有明显增大的趋势,在低、中、高燃速推进剂配方中加入质量分数为5%的ACP,15M Pa下的燃速分别提高11.3%,82.9%,67.8%。Φ64mm发动机试验表明,含ACP的推进剂在发动机中能够稳定燃烧,发动机p-t工作曲线稳定。获得了ACP使推进剂产生非平行层燃烧从而大幅度提高燃速的初步证据。更多还原

【Abstract】 The effects of fast-burning energetic compound ACP with various contents in propellants on the combustion properties of low-burning rate,medium-burning rate,high-burning rate HTPB propellants were investigated by Crawford test and firing test of neutral burning Ф64mm motor.The results showed that the ACP made the burning rate of above-mentioned three kinds of HTPB/AP/Al propellants,and the pressure exponents of the propellants in the pressure range of 6.86-15MPa increase obviously.For instances,5% ACP in propellant samples made the burning rate of above three propellants at 15MPa enhance by 11.3%,82.9%,(67.8%),respectively.The firing tests of neutral burning Ф64mm motors loaded with HTPB/AP/Al propellant grain containing ACP showed stable chamber pressure-time histories.The primary evidence of non-parallel layer combustion in the motors by the fast-burning energetic compound ACP was obtained.更多还原
