Product Overview
This product is a high-performance oleo-pneumatic shock strut designed for light aircraft, medium to large unmanned aerial vehicles (UAVs), and next-generation eVTOL platforms.
Through a precise gas and hydraulic energy management system, it effectively absorbs landing impact and stabilizes the airframe, maintaining excellent durability and reliability even under extreme operating conditions.
Using military-grade 7075 aluminum alloy and a patented gas–oil separation technology, the system provides outstanding damping performance and stability for aircraft operating in extreme environments.
Key Features
