摘要：对一种使用固体燃料的超音速冲压发动机推进装置（SCRAMJET）的性能品质进行了评估。燃料颗粒由有机玻璃制成，呈圆柱形，带有轴对称的圆形穿孔，穿孔向下游方向发散。为了维持燃烧，在初始回流区中需要少量的氢气。在燃烧室入口条件为150 psia、1000 R和马赫数为1.5的情况下，燃烧室出口马赫数保持在约1.4。由于混合条件差，固体燃料的燃烧效率只有57%。
Abstract : An investigation was conducted to evaluate the performance qualities of a supersonic ramjet propulsion device (SCRAMJET) using a solid fuel. The fuel grains were fabricated from Plexiglas and were cylindrical, with an axisymmetric, circular perforation that diverged in the downstream direction. A small amount of hydrogen gas was required in an initial recirculation zone in order to sustain combustion. With Combustor inlet conditions of 150 psia, 1000 R, and a Mach number of 1.5, a combustor exit Mach number of approximately 1.4 was maintained. Due to poor mixing conditions, the combustion efficiency of the solid fuel only 57%.
