This table shows the main types of individual, basic wheeled units (single-wheel unit or bogies composed of multiple wheels) used on most aircraft undercarriages. Symbol. Wheeled unit. Example. 2 wheels, 1 axle. Airbus A380 nose landing gear (consisting of a single 2-wheel bogie) 4 wheels, 2 axles. An Airbus A330 's main landing gear ...
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.
Oleo strut. An oleo strut is a pneumatic air–oil hydraulic shock absorber used on the landing gear of most large aircraft and many smaller ones. [1] This design cushions the impacts of landing and damps out vertical oscillations. It is undesirable for an airplane to bounce on landing as it could lead to a loss of control, [2] and the landing ...

The company has production companies which design, develop and produce structures, landing gear and electrical systems for the aerospace and defense industry. Additional to the production capabilities, it also supplies integrated ...
Landing gear extenders are devices used on conventional or tailwheel-equipped aircraft. They move the wheels forward of the landing gear leg by 2-3 inches (5–8 cm). [1] The installation of landing gear extenders is almost always the result of operational experience with an aircraft design that shows a problem with the landing gear – when ...

The nose landing gear for the Airbus A350.
In aviation, a ground loop is a rapid rotation of a fixed-wing aircraft in the horizontal plane ( yawing) while on the ground. Aerodynamic forces may cause the advancing wing to rise, which may then cause the other wingtip to touch the ground. In severe cases (particularly if the ground surface is soft), the inside wing can dig in, causing the ...
