Compact , High-power Boundary Layer Separation Control Actuation Development

  author={Duane C. McCormick and Steven A. Lozyniak and Douglas G. MacMartin and Peter F. Lorber}
The development of a self-contained, synthetic jet actuator for stall control of a pitching airfoil is described. The test simulates the full-scale (chord, Reynolds and Mach numbers) conditions of rotorcraft retreating blade stall. The required slot velocity was 65 m/s amplitude at 250 Hz (C μ = 0.1% and F =1). The packaging of a selfcontained actuator inside the confined leading edge of the airfoil represented a significant challenge. The approach taken was a voicecoil linear motor driving a… CONTINUE READING
