초록

A mechanical actuating device for moving an aerodynamic or hydrodynamic surface includes at least one flexure member confined in an elastically deformed condition. The flexure member is movable against the force generated by its elastic deformation to move the device into one of a plurality of 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 member. Since the flexure member is always elastically deformed, it "snaps" between discrete, stable ...

[ What is claimed is:] [1.]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 at least one flexure member 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 another different stable position in which said active p...
