Report is concerned with experimental performance of variable geometry, 2-dimensional Coanda wall jet ejector; parameters varied included diffuser length, width and angle, inlet shape, nozzle angle, Coanda surface radius and length, and pressure ratio; best thrust augmentation obtained was 1.56; installation of second pair of slots in diffuser for adding more secondary air increased figure by about 0.05 and additional central nozzle added about another 0.05; pertinence to VTOL-STOL aircraft.
