Attention is given to the possibility of using tangential blowing to control vortical flow on a missile-like slender body at high angles of attack. Emphasis is placed on smoke- and surface oil-flow visualization, force measurements, and velocity and pressure measurements using a 5-hole probe. It is shown that the tangential blowing significantly alters the flow field downstream of the slot and creates large side forces and yawing moments to very high angles of attack. Effectiveness of the tangential blowing is discussed in terms of jet momentum, blowing location, slot area, and Reynolds number. The concept proved to be efficient at small blowing rates and at high angles of attack.
