Abstract
A door arrangement for an aircraft landing gear bay includes a drive mechanism that is asymmetrically located on one side of the door, but symmetrically applies the opening and closing torque to a longitudinally centered location on the pivot axis of the door, to avoid twisting, bending or jamming of the door. The door includes a cover plate mounted on a support frame and a hollow pivot shaft. The door pivots about the axis of the pivot shaft, which is supported in two pivot bearings. The drive mechanism applies a torque to a drive shaft that extends coaxially into the hollow pivot shaft. The drive shaft is connected to the hollow pivot shaft by a torque-transmitting connection only at a location centered along the length of the pivot shaft between the two pivot bearings.
