TL;DR: In this article, an airport terminal gate traffic management system is provided that maximizes efficiency and safety of passenger transfer and aircraft servicing and minimizes aircraft time parked at a terminal, where aircraft are driven forward into and out of gates by controllable landing gear wheel non-engine drive means.
Abstract: An airport terminal gate traffic management system is provided that maximizes efficiency and safety of passenger transfer and aircraft servicing and minimizes aircraft time parked at a terminal. Aircraft are driven forward into and out of gates by controllable landing gear wheel non-engine drive means and parked in a parallel or perpendicular orientation relative to the terminal that facilitates passenger transfer through a maximum number of aircraft doors. Passenger transfer and aircraft servicing may begin upon aircraft arrival using all available accessible aircraft doors. Departing aircraft may be turned by an unassisted pilot and driven forward with the controllable non-engine drive means to a takeoff runway. Airport terminal aircraft gate traffic is most effectively and efficiently managed when a significant number of aircraft using an airport are equipped with non-engine drive means controllable to move them into and out of a parking orientation optimal for passenger transfer.

12 Dec 2002TL;DR: In this paper, the difference between the theoretical and real positions of the centers of the balls are measured, and the adjustments that have to be made to bring the centers back to their theoretical positions is deduced.
Abstract: A landing gear hinge shaft is installed on an aircraft structure using at least two ball joints ( 22 ), at least one of which is adjustable. The differences between the theoretical and real positions of the centers of the balls are measured, and the adjustments that have to be made to bring the centers of the balls back to their theoretical positions is deduced. This is done by making a first adjustment in the axial direction using a shim ( 30 ) and a second adjustment in the radial direction by adjusting the rotation of an inner cage ( 34 ) and an outer cage ( 36 ) of the ball joint. The inner and outer cages have eccentric axes that facilitate the adjustment.

Abstract: The utility model belongs to the airplane landing gear technology, and relates to an improvement of a strut lock in the landing position of an airplane landing gear The airplane landing gear strut lock mechanism provided by the utility model comprises lug pieces (10), a compression spring (11), an upper strut (12), a bracket (13), a knuckle bearing (14), a roller (15), a lower strut component (16), an electric door (17) and a lock hook (20), wherein a connecting hole of a main connecting double lug (10) is connected with a retractable action cylinder; and unlocking and locking of a strut lock can be performed through the retractable action cylinder When the landing gear is in the landing position, the lock hook (20) is clamped on a lug boss of the upper strut (12) through the retractable action cylinder, and at the same time, the movement of the lower strut component (16) is limited by the roller (15) installed on the upper strut (12) The airplane landing gear strut lock mechanism provided by the utility model has the advantages of simple structure, small occupied area and light weight, is fixed reliably, and can undergo and deliver ground loads, thereby being very suitable for light airplanes
