Abstract: An aircraft undercarriage including electrical equipment (2, 3) fastened to a portion (1) of the undercarriage and a lightning protection device (10) comprising at least one shield fastened to said portion (1) of the undercarriage by fastener means so as to extend in register with the electrical equipment (2, 3) in a position that is spaced apart therefrom, the shield comprising at least a first plate (11) made of electrically conductive material that is arranged to absorb a major portion of the heat energy that is generated by the passage of a lightning wave and to discharge the electric charge of the lightning wave. An aircraft fitted with such an undercarriage.

Abstract: An aircraft landing gear includes a strut leg, a bottom portion carrying at least one wheel and mounted to slide in the strut leg, and a plurality of elements such as power electric cables, signal-carrying electric cables, and hydraulic pipes extending toward the bottom portion along the strut leg and terminating at the bottom portion, all of the elements being flexible between a bottom end of the strut leg and the bottom portion of the landing gear. The landing gear includes a first movable support having a proximal end hinged to the bottom end of the strut leg, and a distal end carrying a rack for receiving and guiding the flexible elements. The landing gear also includes a second movable support having a distal end hinged to the bottom portion of the landing gear and a proximal end carrying a rack for receiving and guiding the flexible elements.

Abstract: The invention provides a fastener device comprising a bolt for passing through two adjacent elements. The device comprises an expandable bushing in which the bolt extends, and at least one expander part partially engaged in the expandable bushing in order to cause said bushing to expand radially while tightening the bolt.
