A universal groove-based flow control technology for both marine and aerospace propellers. Increases thrust, reduces cavitation and vibration, and boosts overall efficiency in water and air propulsion systems.
Universal Propulsion Efficiency Upgrade for Air & Water
The Vellox AeroMarine Groove System is a universal groove-based flow optimization method for both marine propellers and aerospace rotors.
Its patented geometry manages boundary-layer behavior, reduces flow separation and cavitation, and increases propulsion efficiency across water or air.
A single enhancement — dual-medium performance.
Key Advantages
- Higher thrust output under identical power input
- Reduced cavitation in marine propulsors
- Reduced vortex losses in air / rotor systems
- Lower vibration, less acoustic noise
- Increased lifespan of propellers and blades
- Works on propellers, rotors, turbines, ducted fans & impellers
Applications
- Boat and ship propellers
- UAV and drone propulsion systems
- Aerospace rotors & prop-fans
- Jet intake fans & boundary-flow compressors
- Water pumps, turbines, hydro impellers
Typical Propulsion Gains vs Ungrooved Blades
| Performance Area | Improvement Range |
|---|---|
| Thrust Increase | +6% to +18% |
| Cavitation Reduction (Marine) | 10% to 30% |
| Vortex Loss Reduction (Aero) | 7% to 16% |
| Energy Efficiency Improvement | 4% to 12% |
| Vibration / Blade Stress Drop | Documented reduction |
(Groove-based boundary layer control technologies — microgrooves, riblets — repeatedly exhibit gains within these ranges.)
Why It Matters
AeroMarine Grooves transform propulsion efficiency without redesigning the propeller or rotor.
This means:
- Longer range per watt/liter
- Lower operational energy cost
- Reduced wear → extended service intervals
- Quieter propulsor signature (air + water)
- Safer hydrodynamic interaction with wildlife
One geometric upgrade — global performance benefit.
