Design of scramjet engine fuel feed system scheme

Abstract

Scramjet is the basis for future hypersonic vehicles, and fuel supply system is an important part in scramjet engine development. Considering of the fuel active cooling, a fuel feed system scheme through valve control was analyzed and designed, and then the control program was put forward for this corresponding scheme. After simplifying the system, each part's mathematical model of the single-point fuel injection system was built. Finally, a PID controller was designed by using Ziegler-Nichols tuning method; simulation results show that the controller can meet the system performance requirements.
