Wind Acting Propulsive Elements TRIZ Cases
- In-Boom Furling Coupling and Ratchet for Splice-Free Reefing
A releasable coupling and ratchet let the mandrel furl one way while avoiding endless-line splice failure and line cutting during boom service.
- Rotatable Cylinder Blade Assembly for Stable Wind Ship Propulsion
A rotatable cylinder between asymmetric aerofoil assemblies stabilizes airflow, cuts separation and vibration, and improves wind-assisted ship propulsion.
- Sail Flying Shape Reconstruction Using Distributed Orientation Sensors
Distributed sail and hull sensors replace cameras to reconstruct sail flying shape in real time despite light, moisture, fog, and mounting limits.
- Selective Flow-Blocking Blade Assembly for Stable Wind Ship Propulsion
A shiftable flow blocker activates the right aerofoil set for port or starboard wind, stabilizing airflow and reducing vibration losses.
