Landing gear systems landing-gear system offering

Landing gear systems is a landing-gear system from Héroux-Devtek with aerospace-grade grade and dual-use market. Landing gear systems from Héroux-Devtek are landing-gear assemblies and components for fixed-wing and rotary-wing aircraft, designed, manufactured, repaired and overhauled by the Canadian aerospace company Héroux-Devtek. The company serves civil and defence customers and works on landing gear as its core business, so the offer is a complete gear installation rather than a single catalogue part.

A landing-gear system supports the aircraft on the ground, absorbs the energy of landing and taxiing, and carries the loads of take-off and braking into the airframe. For an integrator this means that the gear is defined together with the aircraft: the loads, the attachment geometry, the stroke of the shock strut and the retraction envelope are fixed for each airframe configuration. Héroux-Devtek develops landing gear and its actuation as a system, which includes the structural parts and the actuators that extend and retract them.

The company also makes actuation systems and ball screws, hydraulic systems and components, flight control actuators, and structural components. Its programs include landing gear for the Boeing 777 and 777X, the Sikorsky CH-53K helicopter, the Embraer Legacy 450 and 500 business jets and the Learjet 85,. These references show that the company works on large transport aircraft, helicopters and business jets, which are also the classes of platform where hybrid and electric VTOL designers look for qualified landing-gear suppliers.

Production and support are spread over several sites in Canada, the United States, the United Kingdom and Spain. The Canadian site in Saint-Hubert carries out drop testing as well as system and fatigue testing, while Longueuil is the headquarters site for manufacturing, repair and overhaul. Assembly at customer production lines is carried out in Seville, Spain. For operators the company also supplies aftermarket spares and repair and overhaul services.

Typical applications are the main and nose gear of commercial transports and business jets, the skid or wheel gear of military helicopters, and the gear of military aircraft. Buyers of larger unmanned or electric aircraft who need certified structures, actuation and test support can use these capabilities, but the programs named on the sources are crewed aircraft.
