UAVOS has created an advanced leaf spring leg for the main landing gear of an unmanned aircraft weighing up to 1.2 tons. The spring leaf is made of aircraft carbon prepreg by the high-temperature molding procedure, which makes it much stronger, thinner and lighter by 38% in comparison with fiberglass. Inside the spring leaf there is a duct for the brake hose and the landing sensor wire. Modern material and chassis design allowed to save 7 kg of the spring weight (in comparison with fiberglass), to reduce aerodynamic resistance, to ensure the protection of the brake hydraulic system and electrical wiring leading to the chassis.
The leaf spring of the main landing gear leg softens the blows that occur when the unmanned aircraft lands or runs over the uneven surface of the runway. Spring leg weight is 19kg.
