UAVOS Expresses Gratitude to ALTER Technology for Successful Rotor Blade Testing

UAVOS would like to extend its sincere appreciation to the ALTER Technology TÜV NORD S.A.U team for their highly professional work in conducting both overload and environmental testing of the helicopter rotor blades developed for our rotorcraft platforms. Successfully completing these tests will enhance confidence among potential partners and clients, further solidifying UAVOS’s reputation as a dependable OEM with a robust engineering culture.

The test campaign involved simulated overload centrifugal loads exceeding the nominal operational limit of 7,390 N (753.32 kg) and a dynamometer measurement of 389 N (39.65 kg), and confirmed the following key characteristics of the rotor blades:

  • structural integrity under extreme stress
  • resistance to deformation
  • reliability of materials and manufacturing quality.

Environmental tests were conducted to verify the rotor blades’ reliability, durability, and safety under extreme climatic conditions ranging from -55 °C to +70 °C. These procedures are a mandatory part of the qualification process for UAV systems.

"Our collaboration with the ALTER Technology team delivered not only solid data but also confidence that UAVOS' products meet the highest standards in the unmanned systems industry," - said Aliaksei Stratsilatau, Founder and CEO of UAVOS. "The results of the tests enable UAVOS to apply for security and defense grants, which impose strict requirements on unmanned platforms, and allow the company to confidently state that its blades are "designed and tested to exceed operational limits."


UAVOS highly values the technical expertise and professionalism of the ALTA engineers and expresses its deep gratitude for their contribution.
