Unmanned aerial systems developer  Uavos Inc.  (Mountain View, Calif., U.S.) has announced the successful completion of overload structural testing of main rotor blades designed for helicopters with a maximum takeoff weight (MTOW) of up to 50 kilograms.

The tests were conducted by Alter Technology Tüv Nord S.A.U. (Seville, Spain), a provider of testing, inspection and certification services, and confirmed the optimal structural integrity and manufacturing quality of Uavos’ composite unmanned aerial vehicle (UAV) blades, marking another milestone in the company’s expanding OEM program for third-party UAV manufacturers.

Rigorous testing confirmed the blades’ performance under high centrifugal loads, simulating real-world loads well above standard operating limits. During the tests, the rotor blade was subjected to a maximum simulated centrifugal load of 7,390 newtons (753.32 kilograms), a dynamometer measurement of 389 newtons (39.65 kilograms), and deformation was monitored at several points along the blade’s span. All measured deformations remained within the acceptable range of ±36.3 millimeters, and no visible damage was detected either during or after the tests.

“Our blades are manufactured using carbon fiber prepreg under strict quality control, ensuring consistent reliability and safety in field conditions,” says Aliaksei Stratsilatau, founder and CEO of Uavos. “We are end users of our own products and verify their performance and safety daily during real-world UAV missions. Laboratory testing, in turn, provides our customers with confidence in the accuracy of the specifications we declare.”
