Hybrid propulsor for watercraft

This invention describes a boat propulsion system that combines a traditional propeller, a water jet, and a turbine powered by the engine's exhaust. These three elements are arranged concentrically around the boat's main drive shaft, with the water jet surrounding the exhaust turbine and the propeller on the outermost part, featuring a rotating ring to reduce cavitation. The claims specifically detail this concentric arrangement of the water jet around the exhaust turbine.

Why it matters: Advances in real-time sensor technology and control algorithms since 2020 could significantly improve the "self-adjusting" and "optimal thrust and efficiency" aspects of this complex hybrid system. This could make the integrated control of the variable pitch, water jet, and exhaust turbine more effective.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom turbine, water jet, variable pitch propeller, rotating duct.
