Water Acting Propulsive Elements TRIZ Cases
- Submarine Thrust Bearing Mounting to Prevent Shaft Misalignment
Direct hull-end mounting of the submarine thrust bearing maintains shaft alignment under pressure-hull deformation, reducing wear and improving reliability.
- Waterjet Propulsor Shaft Fairing with Airfoil Cross Section
Offset airfoil cross section directs water over the propulsor shaft, reducing turbulence and increasing thrust.
- Marine Propeller One-Way Bearing Mechanism
A marine propeller mechanism uses a one-way bearing to transmit torque from the motor while allowing free rotation.
- Ship Propulsion Device with Counter Rotation and Coupling Unit
A ship propulsion device uses a coupling unit to connect a rotational shaft with a counter rotation unit for front propeller drive.
- Subsea Power Generation via Cable-Driven Turbine Depth Control
A cable-driven turbine system converts fluid currents into electricity using a rotating element linked to a generator.
