Abstract:
The start-up process of gaseous oxygen/ethanol gas generator was analyzed based on the results of hot fire tests. The ignition time and ignition delay are presented for study of the start-up rule. The results suggest that the increase of mass flow rate does not affect the ignition time to a certain extent while it prolongs the ignition delay. The time sequence of oxygen and fuel injected into the chamber has an obvious impact on the start-up process and there exists an optimal interval at which the rapid, smooth and safe start up can be achieved.
