Biomimicry for UAS Blade Design

Docket: UAH-P-15008


The field of unmanned aerial systems (UASs) is rapidly growing, but there are still numerous obstacles and issues for UAS design. For all-electric UASs in particular, energy efficiency and noise are critical considerations

Researchers at UAH have combined biomimicry with rotorcraft blade design to make a more efficient, quieter, and environmentally friendly blade for use on UASs (or “drones”). This design allows drones with propellers that generate as little noise and vibration as possible while also improving efficiency and performance.

The geometry for these UAS blades/propellers is designed to reduce noise, operate with lower power consumption, reduce vibration, offer increased stability in gusts, especially in hover, and enlarge the design parameter envelope. Examples of the latter include maintaining lift while reducing the swept area of the propeller or raising the pitch/angle of attack to allow lower rpm operation while maintaining thrust.
