Challenge
Can thrust be generated for an aircraft or a vessel by arranging two ring-shaped wings in rotation? If so, how would the two wings have to be positioned relative to each other when applied to a fan for an aircraft or a propeller for a vessel? Radially arranged moving wings and guide vanes are widely used in fluid machines. Could this principle be applied to a circular guide vane and a circular rotating wing, and could it be used for an engine?
Invention
The RES-Turbofan Engine uses a smaller, ring-shaped guide vane and a larger, ring-shaped moving wing to create thrust, either on one rotating fan or one rotating propeller. This is achieved by an inclined conical angle of attack on at least one of the ring-shaped wings. During take-off, both ring wings produce thrust, whereas during straight flight, only the larger outer ring wing produces thrust in the direction of travel. This new fluid dynamic mechanism can also be used to advantage on the propeller of a vessel with one or two ring-shaped wings.
Advantages
- Providing a silent running turbofan engine
- More thrust with less energy
- Prevents cavitation on a propeller for a vessel
Applications
- An efficient turbofan engine for all types of aircraft
- A generally applicable ship propeller is also provided
