The performance of a straight wall diffuser and various trapped vortex diffusers was measured with a basic ARL ejector as a test bed. The straight wall diffuser, termed Configuration F by Aerospace Research Laboratories (ARL), yielded thrust augmentation ratios in near agreement with those previously obtained by ARL. Also, as noted by ARL, the thrust augmentation of Configuration F was insensitive to changes in the primary injector pressure. The trapped vortex diffusers investigated were of varying lengths.
