Abstract : The report is a contribution to the research of V/STOL propulsion. The results on a compact two-dimensional rectangular ejector are described. Although thrust augmentation performance was not distinctive, some of the other findings are of value. There appears to be a definite relationship between the flow turning angle and ejector performance. Also an unexpected but beneficial mixing phenomena occurs when two adjacent jets merge. Penetration of the primary flow through the mixing section is important to ejector performance.
