What is the landing gear configuration?
There are two basic configurations of airplane landing gear: conventional gear or tail wheel gear and the tricycle gear. In addition to its two main wheels which are positioned under most of the weight of the aircraft, the conventional gear aircraft also has a smaller wheel located at the aft end of the fuselage.
How do landing gear doors work?
The landing gears and doors are moved by a set of actuating cylinders. For each door, a cylinder opens and closes the door. An Auxiliary Ground Door Opening System allows on-ground access to each landing gear bay for maintenance purposes. This system is electrically operated and controlled from GDO Panels.
What is the purpose of the landing gear on the aircraft?
The purpose of the landing gear in an aircraft is to provide a suspension system during taxi, take-off and landing. It is designed to absorb and dissipate the kinetic energy of landing impact, thereby reducing the impact loads transmitted to the airframe.
Why does the Boeing 737 not have any landing gear doors?
Since the plane was deliberately designed to be low, there wasn’t enough space under the aircraft to accommodate wheel well doors for the main landing gear. If the 737 were to be equipped with landing gear bay doors, and they fail to close up before landing, things wouldn’t be good when the plane touches down.
Why are landing gear tilted?
The purpose of the tilt mechanism is to allow proper truck alignment for retraction into the wheelwell. The wheelwell has limited space, so the truck is “tilted” in such a way that it can fit in smoothly.
Can planes land without landing gear?
A belly landing or gear-up landing occurs when an aircraft lands without its landing gear fully extended and uses its underside, or belly, as its primary landing device. During a belly landing, there is normally extensive damage to the airplane.
