Abstract: The invention concerns an aircraft with engine pods located outboard on the wings and tiltable about a transverse axis. A fixed wing centerpiece is provided which terminates at the outside in each spanwise direction in a separation location. A through tubular spar is rotatably supported in the wing centerpiece. This tubular spar serves as a support for the outer wings which continue beyond the separation locations and which, together with the engine pods located there, form a unit which can be jointly swivelled or tilted.

Abstract: This invention relates to an improvement in a retractable landing gear for jumbo aircraft, in particular of the high-wing monoplane design, with a number of steerable landing units which are retractable into wells in the aircraft fuselage, the improvement comprising (a) means mounting a plurality of landing gear unit means which are spread into two or more rows that extend predominantly over a range at the aircraft fuselage running in the aircraft longitudinal direction, (b) said landing gear unit means and frames belonging to the airframe structure being designed in the manner of a grid division in which, between two particular unencroached main frames of the structure, a particular landing gear unit of one row is arranged and including means to retract it into well means between the frames, and (c) all landing gear units being made of identical components and being of the same dimensions.
