Wheels On Large Airliners
WHY
ARE THERE SO MANY WHEELS ON LARGE AIRLINERS?
By Airline
Ratings
With large super-jumbo airliners like the Airbus A380 and Boeing 747-8 weighing nearly one million pounds at takeoff, their landing gear has to be designed not only to take all that weight while on the ground, but distribute it evenly so the aircraft does not crush the concrete runway or asphalt taxiway below.
.
Even smaller
aircraft are equipped with landing gear designed to distribute their weight
evenly for runways, taxiways, and ramps at the smaller airports they serve
around the world.
To solve this weight-distribution problem, aircraft designers
initially came up with two and four-wheel “bogies” mounted on two main landing
gear struts that effectively spread the airliner’s footprint weight very evenly
on the ground.
With the advent of wide-body
jumbo jets, additional landing gear struts and wheels were added either under
the center fuselage, or just inboard of the wing root.
The Boeing 777 features a
unique landing gear design with six main wheels located in tandem on each main
strut.
