What is the aircraft landing gear system?
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.
What are the types of landing gear?
Landing gear usually comes in three basic wheel arrangements: conventional, tandem and tricycle-type. Beyond this, landing gear is then classified as either fixed or retractable. Fixed landing gear hangs underneath an aircraft during flight, whereas retractable landing gear is stowed inside an aircraft during flight.
How many landing gears does an aircraft have?
In modern aircraft, there used to be two sections of landing gear, (1) main landing gear and (2) secondary landing gear. Main landing gear, positioned nearest to the CG of the aircraft, touches the ground first while landing and leaves the ground last during takeoff.
What are the functions of landing gear?
The main functions of landing gear, undercarriage to the primary structure of the aircraft, are to enable the aircraft for a taxi, safe landing and takeoff, and to support the aircraft in the rest of the ground operation.
What is landing gear made of?
This is why the landing gear is usually made of steel, which is robust, but heavy (which is why it is not used on other parts of the plane). Some parts are also made of titanium alloys. The wheels are often made of very thick rubber to help absorb shock and decelerate the plane as it lands.
What material is used for landing gear?
Landing gear has to support the entire weight of the aircraft, so it has to be incredibly sturdy. This is why the landing gear is usually made of steel, which is robust, but heavy (which is why it is not used on other parts of the plane). Some parts are also made of titanium alloys.
Who invented the landing gear?
Wheels-up! The retractable landing gear that is now commonplace on commercial and military aircraft was first developed for Glen Curtiss’ Triad airplane in 1911. This aircraft was amphibious, so the retractable wheels were used to help the Triad take-off or land on water.
Who makes landing gear for Boeing?
UTC Aerospace Systems
The Boeing-designed landing gear is being produced by one of the company’s longtime suppliers, UTC Aerospace Systems, headquartered in North Carolina. Hamatani is already looking forward to the first 737 MAX 10 delivery in the 2020 time frame.
