AFRL Proves Feasibility of Plasma Actuators

AFRL is laying the groundwork for the development of revolutionary hypersonic aerospace vehicles (see Figure 1). Accordingly, AFRL engineers are examining the feasibility of replacing an air vehicle's traditional, mechanically or electrically actuated flight control surfaces (e.g., wing flaps) with plasma actuators that require no moving parts and are therefore potentially less expensive and more reliable. As part of the laboratory's Boundary Layers and Hypersonics program, the engineers conducted a wind tunnel test to evaluate the feasibility of using plasma actuators for airframe flight control.
