What is landing gear used for?

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 is the landing gear of a plane?

The landing gear is the principal support of the airplane when parked, taxiing, taking off, or landing. The most common type of landing gear consists of wheels, but airplanes can also be equipped with floats for water operations or skis for landing on snow.

What material is used for landing gear?

Landing gear materials must therefore have high static strength, good fracture toughness, and fatigue strength, and the most commonly used materials are high-strength steel and Ti-alloy.

Who invented the landing gear?

It is not very well known that Leonardo da Vinci invented the worlds first landing gear system for an aircraft. Obviously while he was designing and contemplating his flying machines he realized the simple rule – “what goes up, must come down”.

What happens when landing gear fails?

In cases where only one landing gear leg fails to extend, the pilot may choose to retract all the gear and perform a belly landing because he or she may believe it to be easier to control the aircraft during rollout with no gear at all than with one gear missing.

What is etops?

Anyone who has taken a long-haul flight might have flown on an “ETOPS” plane without even knowing it. Technically the acronym stands for “extended-range twin-engine operational performance standards,” and it references planes that are capable of flying over places where landing areas are sparse or non-existent.

Why steel is used in landing gear?

6.1 Ultrahigh Strength Steels for Airframe Structures Landing gear structures need materials with high static and fatigue strength, high stiffness, good toughness, and resistance to environment and wear while also meeting the need for low cost and weight [1].

What are the three types of landing gear?

Landing Gear Arrangement. Three basic arrangements of landing gear are used: tail wheel-type landing gear (also known as conventional gear), tandem landing gear, and tricycle-type landing gear. Tail Wheel-Type Landing Gear. Tail wheel-type landing gear is also known as conventional gear because many early aircraft use this type of arrangement.

How are the 4 types of landing gear struts work?

How The 4 Types Of Landing Gear Struts Work Rigid Struts. Rigid struts were the original type of landing gear. Spring Steel Struts. One of the most common landing strut systems on general aviation aircraft is the spring steel strut. Bungee Cords. Bungee cords are often found on tailwheel and backcountry airplanes. Shock Struts. Smoother Touchdowns Through Engineering.

What is a conventional landing gear aircraft?

Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail. The term conventional persists for historical reasons, but nowadays most aircraft—including all jet aircraft—are configured with tricycle gear.

What is a tandem landing gear?

The main landing gear is in two sets that are located one behind the other on the fuselage. The tandem landing gear allows the use of a highly flexible wing, but it may also require the use of small wheels on the tips of the wings to keep the wings from scraping the ground. BOGEY.
