6 June 1997 Adaptive, split-flap actuator for retreating blade stall control
Author Affiliations +
The primary purpose of this paper is to present a conceptual design for an adaptive materials driven actuator, to be used for rotorcraft retreating blade stall control. The displacement of a single induced strain actuator is hydraulically amplified and the resulting output displacement is used to actuate a split-flap. Such an actuator is designed to produce high displacements through high amplification factors. The actuator design procedure is presented for a sample case. The required actuator force, displacement and amplification are computed. The effects of the flap deployment on the performance of the helicopter are not presented.
