UAVOS Inc., a developer and manufacturer of advanced unmanned systems and components, today announced it is supplying high-performance rotor blades to U.S. aerospace startups participating in the DARPA Heavy Lift Challenge. The competition calls on developers to design and build an unmanned helicopter capable of carrying four times its own weight, a breakthrough capability with no precedent in operational rotorcraft. In this effort, UAVOS is supporting participating startups as a technology and supply partner, providing rotor blades engineered to meet the demanding performance standards required for advanced heavy-lift unmanned rotorcraft.
UAVOS rotor blades are manufactured using an advanced construction approach based on the latest carbon multi-cross-layer technology and core sintering, without additional mechanical processing. This design ensures excellent geometric stability, structural reliability, and consistent performance under challenging operating conditions.
The blades incorporate the NACA 23012 airfoil, selected by UAVOS engineers for its aerodynamic efficiency and enhanced performance under high-load conditions. Special attention has also been given to blade twist optimisation, a critical factor in rotorcraft efficiency. Optimised twist geometry helps reduce power consumption and improve flight endurance, key advantages for heavy-lift unmanned helicopter platforms. Together, these features maximise aerodynamic efficiency and extend operational flight performance.
UAVOS rotor blades have also been tested for overload resistance and environmental reliability by an independent European laboratory, further confirming their suitability for demanding unmanned rotorcraft applications. The blades offer a proven service life of 3,000 hours.
