Plasma Enhanced Aerodynamics and Actuator Health Monitoring for Aerospace Applications

The primary goal of the Phase II program to advance plasma-enhanced aerodynamic control (PEAC) concepts, methods, and techniques to improve V-22 Osprey wing aerodynamics that directly impact efficient cruise and hover. Replacing passive vortex generators with active, dielectric barrier discharge (DBD) plasma actuators on the V-22 wing, in particular, could result in dramatic improvements in the cruise efficiency and range; this also provides for maximum impact and transitionability to flight test demonstrations. Specific technology development areas in the Phase II program will include plasma actuator materials and designs, active flow control (AFC) methods, and a plasma actuator health monitoring system that is suitable for flight applications. PEAC component technologies will be developed, demonstrated, and integrated into a prototype V-22 wing demonstration system. Other performance benefits will be explored by applying plasma actuators on the wing-flap and fuselage sections of the V-22 aircraft which will impact aerodynamic download and vehicle drag.
