讨论了两种金属基固体燃料以测定其燃烧性能和热物理特性。发现镁基固体燃料的燃速只随介质压力增加而增加。对硼基固体燃料的点火和燃烧性能的研究表明,硼可以大大地降低聚(BAMO/NMMO)的点火延迟时间。在确定燃料试样的热物理特性时,提出了一种表面下温度测量方法,以测定试样的导热系数对温度的依赖关系。这些结果与用激光-闪光法取得的结果很符合。
Two metal-based solid fuels have been discussed to determine their combustibility and thermophysical properties. Found that the burning rate of magnesium-based solid fuel only increases with the medium pressure. Studies of the ignition and combustion properties of boron-based solid fuels have shown that boron can greatly reduce the ignition delay time of poly (BAMO / NMMO). In determining the thermal physical properties of a fuel sample, a subsurface temperature measurement method was proposed to determine the temperature dependence of the thermal conductivity of the sample. These results are in good agreement with the results obtained with the laser-flash method.
