| Abstract: | To investigate the phenomen about fuel-supplied oscillation of ramjet cruising stage in simulation experiment, fuel control system was fully modeled with AMESim and numerical simulation was carried out. The results show that fuel - supplied oscillation can be effectively avoided by matching flow characteristics of PWM electromagnetic valve with hydraulic orifice in front of control chamber and adjusting PID parameters when main valve damp ratio is given. Engineering analysis can be satisfied with this conclusion. |
