A mechanical actuating device for moving an aerodynamic or hydrodynamic surface includes plural flexure members confined in an elastically deformed condition. The flexure members are movable against the force generated by their elastic deformation to move the device into one of at least three stable positions, in which the device, and therefore the aerodynamic or hydrodynamic surface, are held by the force generated by elastic deformation of the flexure members. Since the flexure members are always elastically deformed, the device "snaps" between discret...
1. An actuating device for moving an aerodynamic surface subject to fluid forces resulting from relative movement of the surface and a fluid, the actuating device comprising an active portion including a plurality of flexure members confined in an elastically deformed condition and being movable between one stable position in which said active portion is elastically deformed to exert an actuating force for holding the surface in one position against a fluid force thereon and at least two other different stable positions in which said active portion is el...
