Bilge Keels TRIZ Cases
- Stabilizing Fin Control for Low-Speed Ship Roll Damping
Continuous fin motion based on roll rate damps low-speed ship roll while reducing transverse jolts and improving comfort.
- Continuous Stabilizing Fin Motion for Low-Speed Ship Roll Control
A continuous fin motion law linked to roll rate damps ship roll at low speed while avoiding bang-bang jolts and unstable balance.
- Outboard Ram Air Fins for Stepped Hull Stability
External strakes channel compressed air beneath the hull to maintain water contact and prevent unwanted pivoting during high-speed turns.
- Porous Bilge Keel Leading Edge for Drag Reduction
A bilge keel with a porous leading edge reduces normal forces from flow misalignment.
- Ship Trim Tank and Retractable Bilge Keels for Roll Stability
Dynamic trim tanks and retractable bilge keels reduce roll at low speeds while minimizing drag during high-speed operation.
- Strake Geometry for Pontoon Stability and Handling
Configured outer and inner strakes manage hydrodynamic forces to reduce porpoising while maintaining vessel stability.
