An aircraft control surface deployment system for an aircraft structure, that can be a spoiler deployment system for an aircraft wing, includes a cam body, an actuator, and a coupling mechanism. The actuator moves the cam body such that it raises and lowers the aircraft control surface. The actuator is connected to the cam body via the coupling mechanism. The coupling mechanism has a first portion connected to the cam body and a second portion connected to the actuator, configured such that the coupling mechanism allows some free relative movement and rotation of the first and second portions. Loads transverse to the axis of movement of the actuator, resulting from relative movement of the cam body, are not transferred to the actuator.

An aircraft assembly is disclosed having a cover with an outer aerodynamic surface and an aperture with a stop adjacent an edge of the aperture, and a moveable device for extending through the aperture in the cover. The moveable device carries a panel attached to the moveable device by a plurality of leaf springs. The assembly is configured so that when the moveable device is moved towards a retracted position the panel bears against the stop forming a substantially flush surface with the outer aerodynamic surface of the cover surrounding the aperture. The panel is displaced from the moveable device by elastic deformation of at least some of the leaf springs.

An aircraft wing including a wing structure supporting a wing cover having an outer aerodynamic surface, and a pop-up spoiler unit including an actuation mechanism and a spoiler coupled to the actuation mechanism. The spoiler is moveable by the actuation mechanism to deploy through an aperture in the wing cover. The pop-up spoiler unit is mounted to the wing structure to be substantially isolated from wing bending deflections. The wing structure has a neutral plane which is substantially neither stretched nor compressed during bending of the wing structure. The pop-up spoiler unit is mounted to the wing structure at only two pin joints each having a respective pin axis about which the pop-up spoiler unit is substantially free to rotate, and each pin axis substantially lies in the neutral plane.

An aircraft assembly with a hot air exhaust outlet. The aircraft assembly has an assembly surface over which a hot-air exhaust flow from the hot-air exhaust outlet is exhausted. The aircraft assembly also has a vortex generator with a flow surface. The flow surface lies in an air flow over the vortex generator. The flow surface is arranged to interrupt the hot-air exhaust flow and generates a flow vortex to cool the air flow over the assembly surface.

A slat () for the leading edge of a swept aircraft wing includes slat tracks () that dictate the path of movement of the slat as it moves from a retracted position (FIG.) to a fully deployed position (FIG.). Each slat track () has a shape that follows a helical path. The motion of the slat thus includes a component of rotation about a first axis, which may be perpendicular to the line of flight () and a component of translational movement parallel to the first axis. When viewed from above the slat may move predominantly in a direction parallel to the line of flight ().

A spar assembly for an aircraft wing extends between an upper cover and a lower cover and includes linkages spaced consecutively along the length of the spar assembly, each linkage extending from an upper pivot, to a lower pivot, thereby joining upper and lower attachment structures of the spar assembly together. Each linkage includes a pair of fixed-length links pivotably connected at one end about a center pivot and pivotably connected at respective other ends. The spar assembly includes a drive bar connected to the center pivot of each of the linkages, and an actuator arranged to move the drive bar along the length of the spar assembly. When the actuator moves the drive bar along the length of the spar structure, the links in each pair of links are rotated relative to each other about the center pivot, thereby moving the upper and lower covers and warping the wing.
