United States Patent Application

View the Complete Application at the US Patent & Trademark Office
An aerodynamic hollow blade clamp support is disclosed. This aerodynamic hollow blade clamp support allows the thin blade wall to resist deformation and cracking from blade clamp pressure stress. These hollow blade clamp supports fill the blade hollows for at least the blade length under the blade clamps. These hollow blade clamp supports reduce the number of integral blade support webs and thus the weight of the overall blade length. The reduction of hollow blade weight reduces blade centrifugal stresses during blade rotor overspeed.
