TECHNOLOGY/PRODUCT OVERVIEW
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.
Due to centrifugal force, the “winglet” used on wings moving in a linear direction cannot be used in the case of a rotating system.
Elimination of blade tip vortices of aircraft propellers
The blade tip vortex is a powerful phenomenon that develops very quickly. Especially for wide-end propellers a significant amount of blade tip vortices is generated.
The consequences of blade tip vortex include noise, structural vibrations, and reduced efficiency and performance. The detached vortex can damage the blade tip, which in turn decreases the lifespan of the blades, necessitating more frequent replacements
The technical solution provides an approach to eliminate blade tip losses. The elimination of turbulence causing energy loss on the blade tips means greater drag force, torque, and efficiency. Vortex interference is used to eliminate vortices and turbulence that cause losses at the blade tips.
The structural solution has resulted in an 8-13% increase in air time, thereby improving range and fuel efficiency, depending on flight conditions. These findings are supported by a recent patent search report.
