Abstract:
1. A vane for use in a turbine comprising: (a) a flexible exchange of momentum surface adapted to receive mechanical kinetic energy by exchange of momentum from an impinging, moving fluid; and (b) a resilient, buckleable stiffening means comprising a substantially longitudinal region of said flexible exchange of momentum surface extending out from the plane of said flexible exchange of momentum surface which stiffens said flexible exchange of momentum surface thereby making said flexible exchange of momentum surface substantially rigid until said impinging, moving fluid exerts a force against said flexible exchange of momentum surface which exceeds a predetermined magnitude causing said resilient, buckleable stiffening means to buckle and remain buckled allowing said flexible exchange of momentum surface to become flexible until said impinging, moving fluid exerts a predetermined lesser force against said flexible exchange of momentum surface allowing said resilient, bucklable stiffening means to unbuckle and said flexible exchange of momentum surface to return to its original shape and rigidity.
