Abstract

To study the change regularity of airflow in the combustor of scramjet engine,the influence coefficient method was used to mode the quasi one-dimensional model of scramjet combustor,which contained some influence factors such as fuel quality flow,wall heat transfer,cross-sectional variation and wall friction.The conversion boundary conditions of the three modes of the combustor were also presented in this work.A single-module scramjet engine was taken as study object.The effects of fuel equivalent ratio and attack angle on airflow parameters were simulated under scramjet modes without shock-wave and with oblique shock-wave.The presented model provides a method of the overall design of scramjet engine and performance analysis.

Key words
