Landing Gear Airplane
Airplane tires are a subject that I have never really thought about until just lately when my eight years old granddaughter asked what would happen if an aeroplane got a flat tire. I told her that I did non think that they could. Until I looked into it, I did not know just how close to right I came. The aeroplane tire is an amazing design of technology. It has to withstand extreme motor(a) force; it mustiness bear the weight of the aircraft and absorb the shock of that weight when landing. The average Boeing 747 commercial passenger jet weighs approximately 180 tons or 360,000 lbs. That is a lot of weight to drop on a tire moving over a hundred miles per hour.
Aircraft tires have to have excellent traction while maintaining support under extreme weight. However, unlike a car tire, an aeroplane tire will not experience a high volume of rotation in its lifetime. This adds to the seniority of the tire. An aeroplane tire will obviously have to have some flexibility however; the flex factor is not as great as on a regular vehicle tire. This is because airplane tires only flex on landing.
Most standard plane tires ar a pneumatic tire, which means that the tire uses air and inflates. Airplane tires use some measure or air although non for the same reason a car tire would. A car runs pneumatic tires to help ensure a smooth ride and increase the mileage. Airplanes use it merely as an shock absorption when touching down. They do in conjunction with the systems shock absorbers.
The airplane tire is made up of bead corduroys that ar tightly wrapped with a carcass with its ends turned at an upwards angle that matches the body or fuselage of the planes angle. There is another(a) row of twilled beads that ar wrapped in the opposite direction and these layers continue throughout the construction of the tire. An extremely durable and strong rubber material is used. The high modus cords ar entwined into the rubber at a proportion of 6 for every 28 per inch making it very dense and yet pliable enough to give when it hits the runway at one hundred and fifty miles per hour which is the speed that a plane the size of a 747 mustiness travel when it touches down.
Since we have used the 747 as an example, we will continue to describe how the landing gear plays its part in protecting the wheels and placing them for landing. The landing gear is retractable on this type of aircraft including the littler wheels in the front of the plane making it a tri-touchdown point, wheeled aircraft. The nose wheel assembly is exactly like the four sets of shock absorbing main wheels except they are slightly smaller. There ar a total of 18 wheels counting the two nose-cone wheels, which ar only used for weight bearing to keep the nose of the plane off the ground. They ar positioned side by side and are separated by a small axel and cover. There are four sets of four wheels. Two sets in a cluster of four each under the wings and two sets again clustered in fours, side by side under the fuselage. They all retract into the plane to reduce drag during flight. The front wheels also retract although they are positioned so that they do not present themselves as drag.
The majority of all landing gear work through hydraulics but can be cranked up and down manually in the unlikely event of hydraulic system failure. While the smaller wheel can be physically turned left or right from the cockpit to steer the taxiing aircraft, the actual “steering” is done by applying the brakes on one side or the other causation the plane to turn in the opposite direction.
When you arrive at London’s Heathrow Airport, you will need wheels to take you home, to take you to your hotel, or to take you to the great tourist attractions in London. Except the wheels you need will be attached to a vehicle. The best place to find reliable wheels with great client service in London is Leading Route Cars.
