Roll Moment Characteristics of Asymmetric Tangential Leading-Edge Blowing on a Delta Wing

The concept of asymmetric tangential leading-edge blowing (TLEB) for the control of separated vortical flows is presented. Experimental results for the development of roll moment on a delta wing at high angles of attack and sideslip have been obtained and the underlying flow mechanisms examined. The application of the concept as an aircraft control system is discussed.
