What is the landing gear system?
The landing gear system on the orbiter is a conventional aircraft tricycle configuration consisting of a nose landing gear and a left and right main landing gear. Each landing gear includes a shock strut with two wheel and tire assemblies. The nose and main landing gear can be retracted only during ground operations.
What are the main parts of landing gears?
A Landing Gear system comprises of many structural and system components. The structural components include Main fitting, Shock absorber, Bogie beam/ Trailing arm, Axle, Torque links, Drag/ Side braces, Retraction actuator, Down lock mechanism, Up lock, Wheel, Tire etc.
Which is an example of landing gear retraction?
The correct operation of any aircraft landing gear retraction system is extremely important. Figure 4 illustrates an example of a simple large aircraft hydraulic landing gear system. The system is on an aircraft that has doors that open before the gear is extended and close after the gear is retracted.
How does the landing gear work on a light aircraft?
Electrically operated landing gear systems are also found on light aircraft. An all-electric system uses an electric motor and gear reduction to move the gear. The rotary motion of the motor is converted to linear motion to actuate the gear. This is possible only with the relatively lightweight gear found on smaller aircraft.
How is a cantilevered landing gear system modeled?
Cantilevered landing gear units can be modeled by lumped parameter systems, consisting of one, two or more degrees of freedom. These will always include the fore-and-aft bending mode of the gear, but may also include other freedoms, such as incremental wheel and tire rotation.
What kind of landing gear does a narrowbody aircraft have?
Narrowbody aircraft have twin-wheel main landing gear legs. Widebody aircraft main legs have multiple-axle bogies . High-wing cargo aircraft have pontoons for the main gear. Aircraft landing gear includes wheels equipped with solid shock absorbers on light planes, and air/oil oleo struts on larger aircraft.
