UAVOS Inc., a manufacturer of unmanned aerial systems (UASs), has announced the successful testing of a landing gear leaf spring system as part of its Medium Altitude Long Endurance (MALE) unmanned aircraft program.

The leaf spring system is made of aircraft prepreg carbon using a high-temperature molding procedure, which makes it 50% stronger, thinner and lighter than the most commonly used steel. This system offers a significant reduction in aerodynamic drag and in fuel consumption of aircraft while notably increasing flight performance. The advanced main landing gear leaf spring system is designed to support aircraft weight up to 1,200 kg. Systems running through the leaf-spring are hydraulic tubing, axles to connect the wheels, and brake system components. Spring leg weight is 19 kg.

Rigorous ground-based proof tests conducted by UAVOS’ team confirmed that the leaf spring system will be able to withstand all the aircraft stresses and strains associated with takeoff, flight and landing as well as soften the blows that occur when the unmanned aircraft lands or runs over the uneven surface of the runway.

“We are continually seeking ways to improve our unmanned platforms, making them more relevant for our customers’ emerging needs,” said Aliaksei Stratsilatau, CEO of UAVOS. “We’ve designed new heavy-weight landing gear, which greatly extends our MALE UAS endurance while further increasing their operational flexibility.”

UAVOS’ MALE UAS program aims to design, develop and launch advanced aircraft, thus contributing to growing the unmanned systems industry. Data collected from the test will inform UAVOS’ developments of future medium altitude long endurance unmanned aircraft capabilities.
