| Abstract: | A dynamic nonlinear mathematics model of fuel system was set up for the high-frequency pulsation of fuel pressure in a turbo jet.The stability of the system was analyzed with whole-scale-subsection linearization.It was confirmed that high-frequency pulsation was caused by the instability of the system.An improvement method was proposed on the basis of the analysis of the relation between system parameters and system stability. |
