Abstract
An aircraft fuselage includes a stretched-quadrant fuselage segment having from to four stretched-quadrant fuselage projections spaced at intervals around the fuselage. The stretched-quadrant fuselage segment enables an aircraft to be configured for three-across seating rows and for carrying an LD-3 unit load device inside the fuselage with the seats removed.
Claims11
A fuselage for an aircraft, comprising:
- a flight deck segment;
- a first of a stretched-quadrant fuselage segment joined to said flight deck segment, said stretched-quadrant fuselage segment comprising:
- a fuselage wall extending longitudinally from a first end to a second end of said stretched-quadrant fuselage segment, said fuselage wall enclosing a void space configurable as a cabin having a cabin floor, said cabin configured to accept a seating row including up to three passenger seats attached to said cabin floor and further configured to accept above said cabin floor an LD-3 unit load device having an overall height dimension of 64 inches (163 centimeters), a longest dimension of 79 inches (201 centimeters), and a third dimension across opposing sides of 60.4 inches (153 centimeters), said LD-3 unit load device positionable with an angled panel on said LD-3 unit load device extending in a transverse direction across said stretched-quadrant fuselage segment;
- said fuselage wall having an interior surface formed with an interior transverse width in a range from 92 inches (234 centimeters) to 104 inches (264 centimeters) and an interior height in a range from 92 inches to 104 inches, said interior surface having a longitudinal centerline positioned halfway along said interior transverse width and halfway along said interior height;
- said fuselage wall formed with a first of a stretched-quadrant protrusion, said stretched-quadrant protrusion formed by a displacement of said interior surface away from an inscribed circle centered on said longitudinal centerline, said inscribed circle tangent to said interior surface at opposite ends of a transverse horizontal axis passing through said longitudinal centerline;
- said displacement having a maximum separation distance from said inscribed circle to said interior surface in a range from one inch (2.5 centimeters) to four inches (10.2 centimeters);
- said first stretched-quadrant protrusion formed above said transverse horizontal axis with said maximum separation distance located along said interior surface at an angle of 45 degrees from said transverse horizontal axis;
- and
- a second of said stretched-quadrant protrusion formed above said transverse horizontal axis with said maximum separation distance located along said interior surface at an angle of 135 degrees from said transverse horizontal axis;
- a second of said stretched-quadrant fuselage segment joined to said first stretched-quadrant fuselage segment;
- and
- a tail segment joined to said second stretched-quadrant fuselage segment.
