Abstract : Experimental investigations of spanwise blowing as a means of controlling leasing edge vortices and flow separation have been conducted in five phases. Significant results from each phase are reported in this volume. The five (5) phases are: Smoke Tunnel Flow Visualization; Laser Doppler Velocimeter Investigations of the flow field of an under-expanded jet near and paralled to a flat plate; force tests of spanwise blowing over a 45 degree swept horizontal tail configuration; force test with spanwise blowing on an Aspect ratio 4.4, 20 degree swept wing; and pressure tests on the 20 degree wing.
