Abstract
An aircraft has at least two jet-propulsion engines mounted laterally on the fuselage in a symmetrical design in the aft part of the fuselage. Each jet engine is mounted on the fuselage some distance from the vertical plane of symmetry of the aircraft, so that the jet engine, in a so-called half-buried configuration, is partly inside an envelope surface of a theoretical fuselage. The half-buried, jet engines are mounted on a main boom fitted on the vertical plane of symmetry of the aircraft, inside the fuselage in back, of a forward main frame. The tail sections are mounted on the main boom and the boom is integral with structures for transmitting forces into the forward part of the fuselage. The structure is advantageously made of fiber-reinforced composite materials.
Claims12
An aircraft comprising:
- at least two jet-propulsion engines mounted laterally to a fuselage of the aircraft in an approximately symmetrical design in relation to a vertical plane of symmetry of the aircraft in an aft area of the fuselage,
- wherein each of the at least two jet engines is mounted on the fuselage a distance away from the vertical plane of symmetry of the aircraft,
- wherein each jet engine is partly inside an envelope surface of a theoretical fuselage, whose lines correspond approximately to the lines of a fuselage without aft engines or with aft engines mounted in the conventional way outside the fuselage with support struts,
- wherein the jet engines are mounted laterally on a main boom formed by a centered box structure on the vertical plane of symmetry of the aircraft, with said box structure being inside the fuselage in back of a main forward frame of a pressurized area of said fuselage and the main boom includes a first extension that extends from the main boom and connects the main boom with an upper portion of the pressurized area of the fuselage in front of the main forward frame in a direction of movement of the aircraft in flight, upstream from the jet engines, and a second extension that extends from the main boom and connects the main boom with a lower portion of the pressurized area of the fuselage in front of the main forward frame in the direction of movement of the aircraft in flight, upstream from the jet engines.
