What is the purpose of retracting landing gear's pivot?
When the landing gear retracts, it is very important for aerodynamics that they retract into the body of the aircraft as much as possible. However, placement of the landing gear depends ultimately on factors such as the aircraft's center of gravity, its weight, its possible fuel load and much more, there may not be a good locaction in the aircraft for the wheels to rectract fully without some kind of articulation. As a result, aircraft designers often must come up with some pretty interesting solutions to enable to landing gear to be retracted fully into a space that is otherwise unused in the aircraft. Often in order for the landing gear to retract into its well, the wheel trucks may have to be rotated or pivoted. Large aircraft in particular often have multiple wheels for each of the landing gear. It is particularly difficult to design a retraction system for these as the wheel trucks may be very large and ungainly. Some large aircraft have the ability to pivot the landing gear to one direction or another for landing. This is done to increase the aircraft's capacity to land in cross-winds. In a strong cross-wind the aircraft may not be able to land gracefully pointed straight down the runway, and so the landing gear may be off-set one direction or another to allow the aircraft to land with a slight crab-angle.
Two kinds of landing gear?
There are many different kinds of landing gear that can be categorized by their geometry and their internal design. There are fixed landing gears that do not retract. These are usually a support that is made of spring steel that has a axle for a wheel. This example is found on small Cessna aircraft. Other fixed landing gear that are attached at a pin joint and have a shock strut to absorb landing loads. Helicopters are good examples as many have a fixed landing gear. The simplest landing gear shock strut is designed to stroke and absorb energy and it has an axle for either 1 or 2 wheels. These usually rotate on a trunnion at the top of the gear to allow retraction by pivoting of the entire gear. A drag brace locks it down into position. Larger gear have a bogie beam or pivot beam that have multiple wheels, either 4 or 6. The bogie beam attaches to the shock strut and is allowed to pivot during landing and taxi. It will have an actuator or locking mechanism to hold the bogie beam in proper position to allow it to retract in to the wheel well. Internal Design The simplest design is the lower half of the strut(called the Piston) is designed to stroke into the upper half (Outer Cylinder). As it does, the piston forces the fluid through an narrow opening (orifice) that restricts the movement and allows the gear to absorb energy. Many Nose landing gears are of this simple design. Other gear designs will allow the Piston to stroke to a point where it contacts a 2nd Stage. This 2nd stage will have higher pressure or an enclosed volume of air that acts as a final cushion to stop the gear. Some gears have a 2nd Chamber at the top of the gear that has its own piston and orifice. As the Piston strokes, the internal pressures build up and push against the 2nd Stage and it begins to stroke and also resist the forces. This example is found in the DC10 or MD11 Main landing gear.
How does a landing gear work?
No.This question probably stems from a misunderstanding of a term. Likely came from the fact that the undercarriage of an aircraft is often referred to, at least in the U.S. as Landing Gear.Answer 2Aircraft landing gears can have gears similar to a car's rack and pinion steering mechanism that turns the lower piston of the Nose landing gear. The rack and pinion would be operated with hydraulic pressure. Reference Airbus airliners. The first answer seems to refer to the retract mechanism. Most gears are retracted and extended using some hydraulic power and the kinematic design of the strut and its links and pivot points.The Concord had a mechanism that pulled up the Main landing gear to make it shorter just before it rotated into the wheel well during Retraction. Otherwise, the gear was too long to go inside the wheel well. I'm not sure exactly how this worked but I think it was with the use of a mechanical linkage that may have used a bell crank or a gear.I don't know of any Landing Gear that uses a ball-screw actuator to retract and extend it, which is commonly used for flight controls.
What are the landing gear sub system?
Not sure exaclty what you are asking. There are many minor systems that relate to the Landing Gear and the wheels and brakes. The aircraft is divided into different categories referred to as ATA categories. ATA 29 is Hydraulic Controls and ATA 28 is Fuel Controls. Landing Gear is covered by ATA 32. Then this category is sub-divided based upon the manufacturer's organization. ATA 32-10 is the Main Gears ATA 32-20 is the Nose Gears ATA 32-30 is gear retraction and extension ATA 32-40 is wheel and brakes and anti-skid ATA 32-50 is steering ATA 32-60 is Proximity Indicatio System Each of these sub-categories that relate to the braking, and steering and retraction are considered sub-systems of the landing gear.
How does an Airplane with its tire burst during take off land?
There would be 2 chooses. If it is not too serious (only one wheel) they can try and land on the remaining wheels. If it is really serious a belly landing would be the next best option.
Does a glider have landing gear?
Yes, most gliders do have landing gear. A common arrangement is a single wheel in the fuselage just forward of the center of weight, with a tiny tail wheel and roller skate wheels at the tips of the wings. The center wheel is mostly enclosed by the fuselage, making the aircraft appear from a distance that it does not have landing gear.
Wheel well of aircraft?
The area where the landing gear of the aircraft is stored when it is retracted. This is at the bottom of the fuselage (mid-section) for the big jets and in the engine nacelle for most commercial turboprops.
What are the advantages of a tail wheel versus a nose wheel on an airplane?
A nose wheel (or tricycle) undercarriage aircraft has the advantage of easier, more stable takeoffs and landings, as well as control on the ground. A tail dragger has better short takeoff and landing characteristics as the wing incidence is higher, but with added difficulty when taxiing and the possibility of ground looping (aircraft pirouettes around one of the main wheels) Aircraft with retractible landing gear benefit from the lighter weight of tailwheel aircraft, plus added simplicity.

How heavy is the nose wheel of Airbus a380?
The nose wheel of the Airbus A380 weighs approximately 1,600 pounds (about 725 kilograms). This weight is part of the aircraft's overall landing gear system, which is designed to support the massive weight of the A380 during takeoff and landing. The landing gear, including the nose wheel, is engineered to withstand significant forces and stresses during operations.
What kind of landing does a pilot aim for on a plane?
The phrase "three-point-landing" comes from the old days of tail-dragger aircraft. In many tail-draggers a perfect landing in windless conditions will result in all three wheels touching down simultaneously. However, most modern aircraft use a "tricycle" style landing gear layout. Instead of the third wheel being on the end of the tail, the aircraft has a third wheel on the nose. This makes the aircraft much easier to steer on the ground. In tricycle-gear aircraft, the pilot lands on the mains first and then brings down the nosewheel as the the airplane deccelerates. In cross-wind landings, the pilot will aim to touch down the up-wind wheel first. This is done in order to mitigate the danger of gusts picking up the upwind wing which could result in all sorts of ugliness.
Why does the wheel goes up when the plane is flying?
That would be retractable landing gear. They're present on aircraft because retracting the landing gear makes the aircraft more aerodynamic by eliminating the drag which would be caused by having the gear permanently fixed or extended. This saves fuel and improves cruising speeds.
What can helicopters land on?
Basically, Helicopters Landing is of Two Types, One is Skid Landing, Wheel Landing. Skid Landing is used for Army, Civil, Ambulance etc.. This type of landing will be on Ground. Wheel Landing is for Navy, where landing will be on Ships.
Is Jet Aircraft Nose wheel is locked when deployed?
None of the landing wheels would not be locked in any sense of the word other than at the gate when the brakes are fully applied.
What is a helicopter chock?
A chock is a wedge placed on either side of a wheel (such as a landing gear wheel) to prevent accidental movement.I'm guessing you're thinking of a chalk, which is a military term used to refer to a specific load of a single aircraft.
What rotates when a plane takes off?
Rotation is when the aircraft pivots around the axis of its main landing gear while still on the ground. At rotation, the nose wheel lifts off the ground while the main landing gear wheels are still in contact with the ground.
Is a conventional landing gear spring steel?
Yeah, usually...a lot of tailwheel aircraft don't have shock absorbers, and making the landing gear out of spring steel lets it deal with uneven runways and the like better than just bolting the wheel to the end of a rigid steel thing.
