Embodiment Construction

[0041] first reference figure 1 Referring to FIG. 3 , aircraft 20 includes a generally cylindrical fuselage 22 to which wing assemblies 26 and tail assemblies 28 are attached. In the illustrated example, aircraft 20 is propelled by jet engines 30 mounted on wing assemblies 26, as figure 1 Best seen. Aircraft 20 may carry any of various types of payload, including cargo and passengers. As used herein, the term "passenger" is intended to include all forms of passengers, including crew members, pilots, entourage and service personnel.

[0042]Now especially with reference to figure 2 As in FIG. 3 , the fuselage 22 broadly includes a crew cockpit 24 positioned forward and a split-level cabin layout 35 that includes a first main-level cabin 32 positioned immediately behind the cockpit 24 and the upper second cabin 34 and the lower third cabin 36, which are located between the main cabin 32 and the tail assembly 28 ( figure 1 )between. Passenger compartments 32, 34 and 36 inc...

Abstract

The invention provides an aircraft with a rear staggered multi-deck fuselage and a method for transforming the aircraft. An aircraft capable of carrying passengers and cargo comprising: a fuselage having a crown and a keel; a first passenger cabin having a first floor located at the front of the fuselage; a first cargo deck located below at least a portion of the first passenger cabin a split-level cabin located at the rear of the fuselage, the split-level cabin includes an upper second cabin and a lower third cabin, the upper second cabin has a second floor above the first floor level, and the lower third cabin is located on the upper third below the second passenger cabin and having a third floor below the first floor level; and a second cargo deck, located aft of the fuselage, below at least a portion of the lower third passenger cabin, wherein the crown section is between the first passenger cabin and the split level The top of the cabin has a substantially constant cross-sectional shape in the fore-aft direction, and the keel below the second cargo deck is lower than that of the first cargo deck.

Description

technical field [0001] The present disclosure relates generally to aircraft fuselage construction and cabin layout, and more particularly to split-level cabin floor construction. Background technique [0002] The operational efficiency of commercial and military aircraft can depend on the efficient use of the volume of space within the fuselage of the aircraft. Optimizing the use of fuselage volume allows aircraft to carry higher payloads of passengers and / or cargo. The ability to carry higher yield payloads reduces operating expenses relative to yield while reducing fuel burn per seat mile and / or ton mile and CO per seat mile and / or ton mile 2 produce. The challenge of optimizing the use of available fuselage volume is complex due to the need to provide passenger comfort and safety while accommodating associated cargo requirements. Ultimately, passenger cabin layout and design must take into account the need for ditch energy absorption in the lower region of the fuselage...
