不同来流条件下固体燃料超燃冲压发动机性能评估
Performance evaluation of solid fuel scramjet under different inflow conditions
摘要
Abstract
Based on the characteristics of solid fuel scramjet,various components were designed preliminarily under the condi-tion of free stream Ma=6 and flight altitude of 25 km.Numerical simulations were performed to analyze the performance variation law of each component and the whole engine under different inflow conditions.The results show that the flow capture ratio approximates 1 under the design point.When free stream Mach decreases to 4,the inlet becomes unstarted.With the free stream Mach increasing,the flame temperature increases and the combustion efficiency decreases gradually.The thrust is largest under the design point,and the specific impulse decreases with the increase of free stream Mach.关键词
