Main landing gear landing-gear system offering

The Safran A400M main landing gear is a landing-gear system for a large military transport aircraft, supporting the airframe during taxiing, take-off and landing. It is built by Safran Landing Systems for the Airbus A400M, a four-turboprop airlifter, and it is listed here as a heavy main gear assembly for large fixed-wing aircraft.

Each side of the aircraft has a main gear made of three independent twin-wheel assemblies stowed in the streamlined fuselage sponsons, which gives six wheels per side and twelve on the aircraft. This layout spreads the load over a large footprint, a high-flotation arrangement intended for operation from unprepared and soft surfaces.

The structural components are made of titanium. This choice gives a favourable ratio of strength to weight and a higher resistance to corrosion than many alternative materials, which reduces the maintenance burden in the field. The main gear is listed as 2.3 m in height and 6 m in length.

For an integrator, the relevant points are the fuselage-sponson installation, the independent wheel assemblies and the titanium structure; loads, attachment geometry and actuation requirements follow from the A400M configuration.

The product is used on the A400M for tactical and strategic transport, including operations from rough airstrips.
