摘　　要：采用药条燃速仪试验和Ф64mm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6．86～15MPa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，15MPa下的燃速分别提高11．3％，82．9％，67．8％。Ф64mm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。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 Ф64 mm 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.
