Effect of injector on pressure oscillation amplitude-frequency characteristics from pipeline to combustion chamber

The process of pressure oscillation propagation from pipe-line to combustion chamber was theoretically researched in this paper;the transfer function was also deduced.The dynamic characteristic of combustion chamber linked with various injectors was discussed.The influence of pipe-line pressure,combustion chamber pressure,injector type and configuration on pressure oscillation propagation process of pipe-line was calculated,so the influence rule of injector on propagation process was gained.
