Parametric Investigation of Thrust Augmentation by Ejectors on a Pulsed Detonation Tube
2005
41st AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit
unpublished
A parametric investigation has been made of thrust augmentation of a 1 inch diameter pulsed detonation tube by ejectors. A set of ejectors was used which permitted variation of the ejector length, diameter, and nose radius, according to a statistical design of experiment scheme. The maximum augmentations for each ejector were fitted using a polynomial response surface, from which the optimum ejector diameters, and nose radius, were found. Thrust augmentations above a factor of 2 were measured.
