Challenge
A significant proportion of a vehicle's driving power is required to displace the fluid in front of the vehicle. Increasing the driving speed causes air resistance to grow exponentially. While air is driven out of the direction of travel at the front of the vehicle, dead water adds to the resistance at the rear end. Can a significant proportion of the energy lost to the displacement of the surrounding fluid be recovered?
Invention
The RES-Traction Wing features an asymmetric wing profile, with the chord aligned with the direction of the deflective fluid at the streamlined front of a vehicle. In a ring or bow shape, the RES-Traction Wing maintains a consistent distance from the streamlined front within the projected maximum cross-sectional area of the vehicle. Consequently, the RES-Traction Wing generates a significant traction force in the direction of motion, far exceeding the resistance caused by the wing itself.
Advantages
- The creation of a traction force in the direction of travel
- Reduces the overall drive resistance of a vehicle
- Substantial energy savings for the engine
Applications
