Abstract: A drive system for an aircraft landing gear is described. The drive system includes a drive pinion, a drive shaft arranged to rotate the drive pinion about a drive axis, and a casing which rotatably supports the drive shaft. The drive pinion is rotatably supported on the casing by a self-aligning bearing. The drive pinion is coupled to the drive shaft by a flexible coupling adapted to transfer torque between the drive pinion and the drive shaft and to permit tilting of the drive pinion relative to the drive axis.

Abstract: The invention relates to a fastener for attaching detachable panels to a support structure, in particular for use in aerospace applications. The fastener comprises a first tapered portion and a second tapered portion, each of the tapered portions having a thinner end and a thicker end, the first and second tapered portions being located axially adjacent each other such that the thicker end of the first tapered portion is located axially adjacent the thicker end of the second tapered portion, and wherein the angle of taper of the first portion is greater than the angle of taper of the second portion. An assembly is also described, comprising a fastener, a support structure and a detachable panel.
