Wind Propelled Vessels TRIZ Cases
- Submerged Sailing Vessel With Keel Above Waterline
A submerged sailing vessel uses a wind-catching assembly above water to propel a hull and keel fully underwater.
- Ship Propulsion One-Way Clutch for Idling Prevention
Forward and rearward one-way clutches engage input shafts only during high-speed rotation, preventing propeller idling from wind or towing forces.
- Flexible Fairing Mainmast for Sailing Boat Aerodynamic Adaptation
A flexible fairing on a sailing boat mainmast twists to align its airfoil with the apparent wind direction.
