摘要：

A new ignition system is applied to pulse detonation engine (PDE), which is a flame jet ignition (FJI) system, to enhance a deflagration to detonation transition (DDT) time and length. Main subjects are studied: to change the FJI parameters of the length, diameter and nozzle diameter, to optimize the best configuration of FJI sub-chamber to obtain its basic design, to compare the results with the process time of DDT of the conventional spark ignition (CSI) system. The most effective structure of the subchamber for the PDE is that the nozzle diameter is 4 mm, the length is 10 mm and the volume is 3.8 cm3. The FJI system is shown to be a more effective ignition system to shorten DDT time by a factor of 1.26 comparing with the CSI system.
