초록

A circulation control aerofoil having an internal chamber for receiving during operation air for exhaust through a circulation control air exhaust slot defined by spaced-apart slot lips is provided with a plurality of actuators of electrically deformable material adapted during operation to cause local bending of the aerofoil structure to which they are attached to selectively adjust the width of the air exhaust slot. The actuators may be piezo-electric actuators.
