| 摘 要： | 通过对超高燃速推进剂（UHBRP）燃速压力曲线的理论分析，提出了一种降低UHBRP表观燃速压力指数的技术途径。实验上采取密度梯度的方法制造药柱，用大容量密闭爆发器测定了密度梯度药柱的燃速，得到了几乎平台型的燃速压力曲线。达到降低UHBRP表观燃速压力指数的目的，数据重复性良好。

| Abstract: | The characteristic burning rate ( u ) pressure ( p ) curves of ultra high burning rate propellant (UHBRP) were analyzed theoretically. A technological method to reduce the apparent burning rate pressure exponent of UHBRP was used in preparation of UHBRP pellets. A large volume closed bomb was used to measure the burning rates of the UHBRP samples. The u p curves of UHBRP of density gradient show the plateau combustion characteristics. |
