摘要
为提高含硼推进剂的能量，在确定基础配方的情况下，采用热力学计算软件。计算了含硼富燃料推进剂的理论能量，讨论了提高含硼富燃料推进剂能量的技术途径。计算结果表明，当推进剂中其他组分含量一定时，增加硼含量、减少AP含量或以HTPB代替BAMO／THF黏合剂，可提高含硼富燃料推进剂的比冲。发动机试验结果表明，在配方中添加质量分数5％～8％的镁粉，推进剂的一次喷射效率大于98％，细粒度硼粉和F类化合物可以提高该推进剂的比冲，而添加F3化合物可将比冲提高到9502N·s·kg^-1。
The energy levels of two sorts of boron based fuel-rich propellant, HTPB/AP/B and rBAMO-THF/AP/ B compositions, have been calculated with special thermodynamics code. It is showed that the specific impulse of the two propellants will both increase with increasing the boron contents in propellant formulations while the AP contents are decreasing and the contents of other ingredients are fixed simultaneously, and the specific impulse of HTPB propellant is higher than that of BAMO-THF propellant while the other ingredients except the binder in both propellants are consistent. According to the calculated results, the baseline formulation of boron based fuelrich propellant has been established to carry out motor tests. It is indicated that the spurt injection efficiency of boron based fuel-rich propellant in spout of gas generator can reach 98% while adding 5%-8% magnesium powder to the baseline formulation. Fine boron powder and compound F have the function of enhancing the combustion efficiency of boron based fuel-rich propellant and accordingly improving the specific impulse in motor test. The speeific impulse of fuel-rich propellant containing compound F3 and boron powders （particle size 2μm） has reached 9502N · s · kg^-1 in ducted motor flight simulation test.
