Abstract

This chapter presents an overview of existing Gurney flap actuation concepts for rotorcraft applications as well as suggests a new concept applicable to airfoils with little space in the vicinity of airfoil toe. Kinematic and dynamic analysis of the mechanism is performed for the required flap motion pattern. A method of calculating maximum normal force acting on Gurney flap is proposed based on inverse dynamics approach. Piezoelectric actuator force-displacement characteristic and mass properties of mechanism parts are also accounted for in the calculations. A working mock-up of the blade section with active Gurney for wind tunnel testing is designed.
