Abstract
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.
Claims19
An aircraft assembly, comprising:
- a cover with an outer aerodynamic surface and an aperture with a stop adjacent to an edge of the aperture;
- a moveable device for extending through the aperture in the cover, wherein the moveable device carries a panel attached to the moveable device by a plurality of leaf springs, and 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;
- wherein the panel is configured to be displaced from the moveable device by elastic deformation of at least two leaf springs of the plurality of leaf springs;
- and,
- wherein an adjacent pair of leaf springs of the plurality of springs are symmetrically positioned with respect to each other across the panel to restrict lateral movement of the panel with respect to the moveable device as the leaf springs deform.

A method of operating an aircraft assembly, comprising:
- providing a cover with an outer aerodynamic surface and an aperture with a stop adjacent to an edge of the aperture;
- providing a moveable device for extending through the aperture in the cover, wherein the moveable device carries a panel attached to the moveable device by a plurality of leaf springs,
- providing an actuation mechanism for moving the moveable device with respect to the cover,
- the method comprising
- moving the moveable device towards a retracted position so that the panel bears against the stop forming a substantially flush surface with the outer aerodynamic surface of the cover surrounding the aperture,
- moving the moveable device to the retracted position so that the panel is displaced from the moveable device and at least two leaf springs of the plurality of leaf springs are elastically deformed, and
- moving the moveable device with respect to the cover by translating the moveable device with respect to the cover.
