为了解决含硼富燃料推进剂在氧弹内燃烧效率低、实验测试值不能正确表征实际燃烧热值的问题,研究了含硼富燃料推进剂燃烧热值测试过程中试样质量和充氧压强对测试结果的影响,在氧弹安全承载范围内,试样质量越大、充氧压强越大,含硼富燃料推进剂燃烧越完全。使用有机溶剂溶解后挥发的混合方式,将作为助燃剂的自制ZS与加工成20目含硼富燃料推进剂实现紧密结合,经过一系列工艺处理制得试样。根据含硼富燃料推进剂在氧弹内的燃烧特点设计加工了专用钨坩埚,使用改进型氧弹式量热仪对试样进行热值测试。实验结果表明,助燃法测试含硼富燃料推进剂的燃烧热值较为有效,解决了含硼富燃料推进剂在氧弹内燃烧不完全以及测试值不能正确表征理论燃烧热值的问题,具有较高的准确性和可靠性。
In order to solve the problem that the boron-containing fuel-rich propellant has poor combustion efficiency in oxygen bomb and the experimental test value can not correctly represent the actual combustion calorific value, the quality and oxygenation pressure of the boron-rich fuel propellant during the combustion calorific value test The impact of the test results, the oxygen bomb within the safety load, the greater the sample quality, the greater the oxygen pressure, boron-rich fuel propellant combustion more completely. After the organic solvent is dissolved and volatilized, the self-made ZS as a combustion improver is closely combined with the 20-mesh boron-enriched fuel-rich propellant to obtain a sample after a series of process processes. According to the characteristics of combustion of boron-rich fuel propellant in the oxygen bomb, a special tungsten crucible was designed and processed, and the calorific value of the sample was tested by the improved bomb calorimeter. The experimental results show that the combustion calorific value of the boron-enriched fuel propellants is more effective than the combustion-supporting method, which solves the problem that the boron-rich fuel propellants are not completely burned in the oxygen bomb and the measured values can not correctly represent the theoretical calorific value. High accuracy and reliability.
