Helicopter landing-gear systems and integration

The Helicopter landing gear is a helicopter landing-gear system from Mecaer Aviation Group with aerospace-grade grade and dual-use market. Mecaer Aviation Group supplies helicopter landing-gear systems, covering the design and integration of undercarriages for rotary-wing aircraft. As a landing-gear system integrator, it offers both clean-sheet design and build-to-print manufacturing, so an airframe maker can either hand over the requirement or supply its own drawings.

The product range comprises nose landing gears, main landing gears and uplocks. The configuration depends on the aircraft, and the gear can be fixed or retractable. Where retraction is needed, the maker provides hydraulic and electro-mechanical systems, which lets the integrator choose between a hydraulic power source already on the aircraft and an electrically actuated solution, a choice that matters for more-electric rotorcraft and eVTOL concepts.

Beyond the structure, the supplier takes responsibility for integrating the gear with the other systems that act on it: wheels and brakes, steering and the aircraft control systems. This integration scope means one supplier can deliver a complete landing system rather than separate parts, which reduces interface work for the airframe manufacturer.

A test laboratory supports the work. The maker lists drop tests at a sink speed of 13 fps and above, limit, ultimate and fatigue load tests, extension and retraction endurance tests, steering endurance tests, nose gear shimmy dynamic testing and environmental testing covering temperature and EMI/EMC. These tests give the data used to demonstrate that a gear design meets its structural and functional requirements.

Typical applications are main and nose landing-gear assemblies for helicopter programmes and for upgrades of existing ones, and landing systems for larger rotorcraft and vertical-lift aircraft that need retractable gear. Buyers should treat the product as a custom-engineered system, defined together with the supplier for each airframe, rather than as a catalogue part with fixed dimensions.
