摘要

The invention is an attitude convertible outboard door for the main landing gear maximizing lift by aerodynamic force of the outboard door after takeoff. The device comprises an outboard door(60) at one end of landing gear(50); a universal joint(10) fitted to door hinge(11) in the outboard door(60); and connecting rods(12,14) fitted to landing gear(50), strut(52), and outboard door(60) by hinges (12a,12b,14a,14b), with connecting rod(14) being longer than connecting rod(12). The rotating shaft(54) fitted to the landing gear (50) strut(52) being the turning axis and the universal joint(10) being the fixed axis so that the outboard door(60) is linked to landing gear (50) operation. The device minimizes drag resistance and optimizes system design by reducing the weight of the hydraulic system which drives the landing gear.
