Abstract:
1. In combination with a hull having a propulsion unit with propeller blades undergoing rotation about an axis extending through the hull for propulsion thereof through a fluid environment, a system for adjusting each of said propeller blades to maintain efficiency of said propulsion of the hull through said fluid environment under widely changing conditions thereof, comprising: actuator means within the propeller blade for adjustment by deflection thereof during said propulsion of the hull; controller means sealed within the hull for regulation of said deflection of the propeller blade by the actuator means in accordance with the changing conditions of the fluid environment, a propeller shaft extending along said axis through the hull between a propulsion source of power and a hub on which the propeller blades are mounted; and wiring means extending through the propeller shaft operatively interconnecting within the hull for effecting said adjustment deflection of the propeller blades and said regulation of the deflection.
