Landing Gear
History and curiosities

Landing gear is one of the most important parts of the aircraft. Being that it supports all of the most critical loads, which are the moment of takeoff and landing. To support their heavy responsibilities, trains together what's most advanced aviation technology. Wheels, tires, brakes and shock absorbers, typical elements of the vehicles do not leave the ground, are also essential for flying devices, although they are less conspicuous and less glamorous than wings and reactors.
Each landing gear can weigh nearly 3 tons? some 3 to 4 percent of all aircraft? but bear to the total weight of this triple shock in the runway. In the case of a Jumbo 747, the largest passenger plane today, the eighteen wheels of the five landing gears takes only 4 hundredths of a second after the meeting with the cement to accelerate at the same speed of the plane, while supporting the impact of 285 tons the aircraft. The friction track increases with the temperature of the tire rubber at more than 80 degrees centigrade. With the tight belt, the passenger feels in the body when a bulkhead at the air outlet of the turbine is driven to change the direction of the momentum, slowing the machine. At the same time, reduce aerodynamic devices support wings in the air and ground to pierce the plane. Sensors installed in the landing gear indicate then that the wheels turn and the dampers are compressed, thereby confirming that the plane is definitely down. It's the time of hydraulic controls acionarem automatic wheel brakes slowing down to about 60 miles per hour. From this point on the pilot usually triggers the handbrakes, and another joystick spinning, leads the unit, now slowly, the parking spot.
Until the next flight, the landing gear will serve as a simple ground support, while the mechanics responsible for maintenance deal to repair or replace worn parts.
In fact, a good measure of this concern is the list of aircraft maintenance from a flight and
