General information
- Short Summary
- A Hungarian technology transfer agency offers its technology. Blade tip vortex quickly affects performance, especially in wide blades. While widening tips boosts power, it also raises vortex losses. Reducing the angle of attack minimizes these losses, enhancing efficiency, lifespan, and fuel savings, and enabling new design possibilities for aircraft and drones. The agency is looking for potential license partners or investors, commercial agreement with technical assistance and R&D partners.
- Full Description
-
A Hungarian technology transfer agency offers a solution to eliminate blade tip vortices in propellers. Blade tip vortex is a powerful phenomenon that develops very quickly. However, ‘widening' the blade tips increases the possibility of greater power and performance, at the same time, the vortex losses generated at the blade tips increase drastically. The solution currently used to reduce the vortices of the blade tips is reducing the angle of attack close to the blade tip. This is how it tries to avoid significant losses. At the same time, naturally, the drag force or the transmittable power decreases.
Eliminating or reducing blade tip losses (eliminating vortices around the blade tip) means significant fuel savings and increased lifespan, efficiency, and performance especially when using wide blade tips.
The elimination of blade tip loss reduces vibrations, thus reducing internal friction of the structure's material, thereby increasing lifespan. This results in significant financial savings, e.g. in the case of a modern blade.
The innovative solution opens up many new possibilities in structural and industrial design. Extreme shapes may be created more easily. There are more possibilities regarding the number, location, and operation of engines, movement, and hovering. Drones may fly for several hours or can have a greater range. This technology is applied in multiple fields: aircraft, drones, and wind turbine.
In essence, the company is searching for dynamic and results-driven partners who can help expand the reach of the elimination of blade tip vortices technology, save fuel and energy, thus contributing to a more sustainable world.
They are trying to achieve possible cooperation by license, investors, commercial agreement with technical assistance as well as looking for R&D cooperations. - Advantages and Innovations
-
These newly developed propellers eliminate harmful turbulence at the tip of the propeller blade. The resulting benefits provide many possibilities for keeping and moving aircrafts and drones in the air:
- fuel can be saved,
- range can be greater,
- time spent in the air can be more,
- vibration generated by the propeller can be reduced,
- lifespan of the propeller can be increased,
- number of propeller blades can be reduced.
- operation can be quieter,
- there can be more favourable flight characteristics,
- energy consumption can be reduced,
- own weight/liftable payload ratio can increase positively.
Advantages of wind propeller
- Blades with greater performance are created
- The tips of the blades become damaged
- Reduced noise
- The vibrations are reduced by widening the blade tips, the vibrations are greater than the land blade
- Greater efficiency and performance
- Longer lifespan: 2-3 years increase in lifespan (basically 12-15 years, 10-15% increase in lifespan)
- It is used for 90-100m long, self-supporting blades
- Performance increase: 8-10%
- Wind turbine blades are exposed to countless physical, mechanical and chemical stresses during operation
- Wind turbine blades are currently dimensioned based on S. Goldstein's fluid mechanics theory. Therefore, the tip of the blades cannot be wide. They are relatively quiet, but the usable power is lower.
- The elimination of blade tip loss reduces vibrations, thus reducing internal friction of the structure's material, thereby increasing lifespan. This results in significant financial savings, e.g. in the case of a modern wind turbine's blade. - Stage of Development
