Abstract: An aircraft fuselage is configured to receive two tanks designed to contain liquid hydrogen. The fuselage includes a first section for a cockpit, a second section for a passenger cabin and a third section (T3) distinct from the first section (T1) and from the second section (T2). The third section (T3) includes two housings each to house a tank. The two housings are arranged symmetrically with respect to a vertical plane of symmetry (P1). This arrangement of the tanks in a section distinct from the other sections allows them to be located as close as possible to the motors that they have to supply.

Abstract: An aircraft (5) including a wing (3) and a winglet (1) at the end of the wing, the winglet including: a root (7); a tip (9); a transition region (11) extending away from the root; and a wing-like region (13) extending from the distal end of the transition region to the tip. When the aircraft wing (3) is under the worst-case static loading, the tip of the winglet is located at the maximum spanwise extent of the winglet (1), but when the aircraft wing (3) is under the no-load condition, the wing-like region (13) is canted inboard such that the tip (9) of the winglet (1) is located inboard of the maximum spanwise extent of the winglet.

Abstract: A method of designing a winglet (3) for an aircraft (7) including: defining the location of the winglet root; defining a maximum height for the winglet tip; defining a maximum span for the winglet; creating the winglet shape by locating the winglet root (13?), locating the winglet tip (15?) at the location of maximum height and maximum span, and connecting the winglet root (13?) to the winglet tip (15?) using a winglet shape. The winglet shape includes a curved transition region (17?) extending away from the root, and a wing-like region extending from the distal end of the transition region (17?) to the winglet tip (15?). The step of creating the winglet shape includes iteratively changing the curvature and/or the location of the center of the curvature of the transition region, whilst maintaining the locations of the winglet root and winglet tip.
