What are the three 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.
How is a landing gear made?
The landing gear manufacturing involves development of many closed die forgings, machined components from ultra-high strength steels, titanium and aluminum alloys. Precision tolerances are required for components like actuator cylinder, piston, shock absorber parts and axle.
What type of material is used for making the 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.
How is landing gear height determined?
In general, the landing gear height is defined as the distance between the ground and the conjunction between main gear strut and the aircraft structure (fuselage, wing, nacelles, etc.). The landing gear height of any aircraft varies depending the loading conditions and where you measure it (nose or main landing gear).
What kind of steel is used in landing gear?
300M steel is widely used for high stress aircraft landing gears and structures; however, this steel is not corrosion-resistant and requires protective coatings.
What are the types of landing gear?
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.
Why is it called landing gear?
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called alighting gear by some manufacturers, such as the Glenn L.
How do you calculate landing gear load?
K = 2 [18,333 x 11,538/(18,333 + 11,538)] = 14,163 lb/ft. Part 23 allows the landing weight, Wt to equal 0.95 x gross weight. For a gross weight of 1,232 lbs the landing weight is 1,170 lbs. The gyroplane has a disc diameter of 30 ft and hence a disc area of p r2 = 3.141 x 152 = 707 sq.
Why is titanium used in landing gear?
Titanium 10-2-3 (Ti 10-2-3) is used in the landing gear instead of steel. The main reason for this change is the reduction of 600 pounds in the aircraft, because the strength to weight ratio of titanium is higher than steel.
Is mild steel used in aircraft?
Aluminum and mild steel have been used in the production of aircrafts for decades, but chrome moly steel is increasingly utilised in aerospace engineering too. As mentioned, the molybdenum content of the alloy vastly increases its strength without impacting ductility or workability.
What are the 4 typical loads on an aircraft?
There are four main load sources acting on an aeroplane – aerodynamic forces, inertia, ground reactions and thrust.
How is aircraft landing gear tested?
For realistic testing, the wheels of the landing gear are accelerated up to landing speed. Then the landing gear is dropped, creating a load similar to a real touchdown. By measuring these forces, the landing gear design can be verified and the forces and moments occurring in the aircraft structure can be determined.
Why titanium is used in aircraft?
For aircraft engines, titanium alloys stronger than pure titanium are used for their light weight, high strength (high specific strength) and heat resistance properties.
Why is pure aluminium never used?
Aluminum as a pure metal is very soft and not suitable for use in making structural components. The addition of other elements creates alloy materials of varying structural strength, corrosion resistance, and workability.
How are the landing gears of a plane designed?
Skis. When an airplane needs to land on surfaces covered by snow,the landing gear usually consists of skis or a combination of wheels and skis.
Tail wheel-type landing gear —The main gear is located forward of the center of gravity,which requires support from the tail of a third wheel assembly.
