Abstract

The overall objective of this STTR effort is to evaluate and demonstrate the potential for well-designed, strategically-located synthetic jet actuators to provide improved aircraft safety by: (1) delaying wing stall and improving aircraft controllability at high angles of attack and (2) providing low-cost actuation redun-dancy to improve controllability in the event of a mechanical control surface failure. Delaying flow separa-tion (i.e., wing stall) and providing "back-up" control power could allow an aircraft to recover from adverse conditions (due to a control surface failure, pilot/autopilot error, etc.) that would otherwise result in a loss of control.
