The invention relates to aircrafts, in particular to aircrafts, which are embodied in a passenger, cargo or cargopassenger variants thereby making it possible to improve performance characteristics by improving the aerodynamic properties thereof. The inventive aircraft having a carrying fuselage comprises a wing, an engine, and a fuselage whose width considerably exceeds the height thereof. A lower surface of the basic and the tail parts of the fuselage have a caved-in form in a cross-section thereof. A lower surface of the flattened front part of the fuselage is arranged at an attack angle with respect to the longitudinal horizontal plane of the aircraft. In addition, the front part of the aircraft has a curvilinear form in the plan view, which successively passes from the narrow front part to the basic large part of the fuselage. A tail group is embodied in the form of a double tail fins which are mutually spaced at a distance of the fuselage width with respect to the longitudinal vertical plane of the aircraft and are mounted at an angle with respect to said vertical plane of the aircraft. <IMAGE> |
