Propulsive Transmission Drive TRIZ Cases
- Marine Propulsion Unit Two-Stem Fastening Hydrodynamic Performance
Two stems extending from the nozzle upper surface create an opening that improves hydrodynamic flow over the propulsion unit.
- Electric Propulsion Device Turning Actuator for Compact Direction Change
A turning actuator rotates the duct and rim assembly to change propulsive force direction, reducing vertical height compared to steering shaft designs.
- Segmented Stator Rim Thruster for Reduced Gap Losses
A rim thruster stator extends over a partial circumferential area of the rotor to minimize gap losses.
