Aircraft fuselage with an upper deck, constructed as a passenger area, and a lower deck, including a freight area, and with a ventilation installation for the upper deck and lower deck, wherein a bilge area is constructed as a vacuum chamber against the freight area and is connected to the lower deck solely via flow orifices in the abutment area between a lower floor and the fuselage wall.

The invention claimed is: 1. An aircraft fuselage, comprising: a rounded frame including an exterior wall and an interior wall, with a peripheral flow passage located therebetween, an intermediate floor dividing the aircraft fuselage into an upper deck comprising a passenger area and a lower deck comprising a freight area, that is positioned within the rounded frame, a ventilation installation comprising compressed air ducts through which fresh air is supplied into the upper deck, a lower floor arranged in the lower deck, a bilge area located below the lower floor, an abutment area disposed within the peripheral flow passage between the lower floor and the exterior wall, a sheet located in the abutment area and having flow orifices extending therethrough, the flow orifices disposed in the peripheral flow passage at the abutment area, wherein fluid communication between the bilge area and the lower deck occurs solely via the flow orifices the sheet running in a longitudinal direction of the fuselage and arranged in the abutment area, and at least one discharge valve disposed in the bilge area, wherein the discharge valve discharges air from the bilge area to the outside of the aircraft fuselage, wherein a pressure in the bilge area is adjustable by operating the at least one discharge valve to be less than a pressure in the lower deck, wherein an exhaust air stream is exhaustible from the upper deck through openings in the intermediate floor into the peripheral flow passage of the lower deck, from the peripheral flow passage downwardly along the exterior wall to the abutment area, through the flow orifices into the bilge area, and from the bilge area to the outside through the at least one discharge valve. 2. The aircraft fuselage of claim 1, wherein the flow orifices are formed by perforations in the sheet. 3. The aircraft fuselage of claim 1, wherein the shape of the exterior wall and the interior wall is such that air flowing in the peripheral flow passage flows tangentially along the exterior wall. 4. The aircraft fuselage of claim 1, wherein the intermediate floor is disposed below a widest cross-section of the aircraft fuselage such that the upper deck is larger than the lower deck. 5. The aircraft fuselage of claim 1, wherein the peripheral flow passage and the bilge area substantially surround the freight area of the lower deck, thereby to insulate the freight area from the environment outside of the aircraft fuselage. 6. An aircraft fuselage, comprising: a cylindrical frame including an exterior wall and an interior wall spaced inwardly from the exterior wall and defining a peripheral flow passage therebetween; an intermediate floor dividing the aircraft fuselage into an upper deck and a lower deck, the upper deck comprising a passenger area and the lower deck comprising a freight area, the upper deck being in fluid communication with the peripheral flow passage; a ventilation installation comprising compressed air ducts through which fresh air is supplied into the upper deck; a lower floor arranged in the lower deck; a bilge area located below the lower floor, the bilge area being in fluid communication with the peripheral flow passage, and the peripheral flow passage terminating at the bilge area; a sheet disposed in the peripheral flow passage adjacent the bilge area, the sheet having flow orifices extending therethrough, wherein fluid flow from the peripheral flow passage to the bilge area occurs solely via the flow orifices the sheet extending longitudinally along the fuselage and arranged adjacent to the bilge area; and at least one discharge valve located within the bilge area, wherein the discharge valve discharges air from the bilge area to the outside of the aircraft fuselage, the at least one discharge valve operable to control fluid pressure in the bilge area, wherein the fresh air supplied to the upper deck from the ventilator system is exhausted therefrom via the peripheral flow passage, downwardly along the exterior wall, through the flow orifices and into the bilge area, and to the outside through the at least one discharge valve. 7. The aircraft fuselage of claim 6, wherein the flow orifices are formed by perforations in the sheet, the perforated sheets being of relatively poor heat conducting capability. 8. The aircraft fuselage of claim 6 wherein lower portions of the interior wall which define the peripheral flow passage also define lower side walls for the freight area. 9. A method of warming an aircraft fuselage of the type recited in claim 6, comprising: flowing heated fresh air into the passenger cabin of the upper deck, the heated fresh air eventually flowing from the upper deck to the peripheral flow passage and then downwardly along the exterior wall into the bilge area. 10. The method of claim 9 further comprising: operating the at least one discharge valve to adjust the fluid pressure within the bilge area, thereby to draw the heated fresh air from the passenger area to the bilge area via the peripheral flow passage and the flow orifices.
