The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
Advanced Supersonic Transport (AST) model in wind tunnel. The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft.
Querétaro: manufacturing of major landing gear components for: A320 main landing gear fitting, A330 main landing gear bogie beam and B787 nose landing gear inner cylinder. Ajax, Ontario: design and development of fully integrated landing gear systems. It also focuses on ancillary systems such as steering control, landing gear control and ...
Beginning about 1946, landing gear manufacturing shifted to include commercial airliners. By the end of the 1990s, Menasco Aerosystems was the free world's largest producer of aircraft landing gear, with plants in California, Texas and Canada.
1969 : Manufacturing of the landing gear for the Apollo Lunar Module in 1969. 1985 : Merging of the corporation (On June 26, 1985) with 2320-4894 Québec Inc., a management company incorporated by the corporation's then two senior executives, Gilles Labbé and Sarto Richer, in connection with the sale by Bombardier Inc. of its shares in the ...
The DC-10 is designed so that if hydraulic pressure to the landing gear is lost, the gear will fall down slightly and rest on the landing gear doors. Placing the regular landing gear handle in the down position will unlock the doors mechanically, and the doors and landing gear will then fall down into place and lock due to gravity. [13] An ...
The landing gear is made in China by a joint venture of Germany's Liebherr and AVIC's Landing Gear Advanced Manufacturing Corp: Liebherr LAMC Aviation. [47] While the airframe is entirely made by AVIC, some systems are sourced from a wide variety of international suppliers, similar to Airbus and Boeing.
In 1956 they were designing and manufacturing aircraft landing gear. There was a large test rig where the wheel assembly was held, the wheel spun up to the equivalent landing speed and then dropped onto the "ground" to simulate the landing process. Measuring equipment recorded the stresses.
