Landing gear
摘要:
A semi-levered landing gear for an aircraft comprises a main shock absorber strut (1) with upper and lower telescoping portions, with the upper portion pivotally connectable to the airframe. The landing gear further comprises a bogie beam (4) to extend fore and aft of the airframe with at least one forward axle and one aft axle for respective forward and aft wheels and a main pivot between the forward and aft axle pivotally connected to the lower portion of the main shock absorber strut and an auxiliary actuator mechanism comprising a spring unit (11) pivotally connected at a lower end to an auxiliary pivot on the bogie forward of the main pivot, and at an upper end to an anchor point (112) offset from the pivot connection of the upper portion to the aircraft fuselage so that during stowing both the strut and spring unit pivot together about different pivot points, which causes a relative longitudinal movement between the main pivot and auxiliary pivot that further tilts the bogie beam to a stowing position.
