摘要:

采用最小自由能法（ｗｈｉｔｅ法），计算研究了增塑剂与粘合剂质量比（Ｐ１、Ｐ０）、固体含量、硼含量、ＨＭＸ含量对用于整体级发动机的含硼ＢＡＭＯ／ＴＨＦ（１：１）推进剂能量的影响。实验研究制得的６５％固体含量的ＢＡＭＯ／ＴＨＦ（１：１）含硼固体推进剂的基础燃速、压强指数较低；φ６５ｍｍ发动机的试车结果表明：实验制得的６５％固体含量的含硼ＢＡＭＯ／ＴＨＦ（１：１）推进剂的比冲效率为８４．４５％。

Abstract:

Based on the minimum free energy method (white method), the effects of mass ratio of plasticizer and polymer (P1/P0), solid loading, boron powder content and HMX content on the energetic characteristics of boron-containing BAMO/THF (1: 1) propellants, which will be used in integrated stage motors, have been studied by thermodynamic calculation. AP/B/ [BAMO/THF (1: 1 )] propellants with solid loading of 65% have been made, the sample has slower burning rate and lower pressure exponent. The test results of 65mm motor show that the specific impulse efficiency of the sample is 84. 45%.
