It has one nose landing gear leg and two main landing gear legs that are placed under the wing and retract into the fuselage. 1.1.1 Tricycle gear layout The tricycle gear (figure 1.1) consists of one nose landing gear leg and two main landing gear legs. When using a tricycle gear, around 13% of the total weight of the airplane acts down on the nose landing gear and 87% acts down on the main landing gear. The weight distribution depends on the position of the center of gravity. The center of gravity on the A320 must be between 17% and 38, 5% on the Mean Aerodynamic Chord (MAC). The location of the MAC can be calculated using the aircraft’s dimensions . Figure 1.1 Airbus 320 Landing gear layout The advantage of the tricycle gear is the stabilizing momentum during touchdown when the aircraft’s longitudinal axis is not parallel to the runway. The drag created by the two main gear wheels is parallel to the motion direction (figure 1.2). This means there is no momentum created however the drag that works on the two main gear wheels to the side creates a negative momentum. This momentum turns the aircraft parallel to the runway again. Fig 1.2 Tricycle gear Another advantage of the tricycle gear is that the aircraft is in a horizontal position when parked on the ground. Unlike the conventional landing gear configuration which has a tail wheel instead of a nose wheel. With the tail wheel causes the airplane to stand in
