Abstract

Based on the characteristics of nose fuel-inlet model solid-fuel rocket scramjet, various components are designed preliminarily under the condition of free stream Ma 6 and flight altitude of 25 km. Numerical simulations are performed to analyze the performance variation law of the second combustor under different flight altitude. The results show that with the flight altitude increasing, the chemical reaction rate and combustion efficiency decreases gradually, which resulted in the decrease of thrust and specific impulse gain of the secondary combustion chamber.

Key words： nose fuel-inlet model; solid-fuel rocket scramjet; numerical simulations; combustion performance
