Mehrzweck-Flugzeuge mit Mehrzweck-Unterdecks und Verfahren zu deren Herstellung

摘要

Transport aircraft, such as a transonic transport aircraft, having fuselages with multipurpose lower decks. In one embodiment, the fuselage (102) is an "area-ruled" fuselage having a first fuselage portion (110), a second fuselage portion (120) positioned aft of the first fuselage portion (110) and at least proximate to a wing (150), and a third fuselage portion (130) positioned aft of the second fuselage portion (120). The first fuselage portion (110) can have a first dimension, the second fuselage portion (120) can have a second dimension less than the first dimension (110), and the third fuselage portion (130) can have a third dimension greater than the second dimension. The fuselage (102) can further include an upper deck (106) extending at least within the first and second fuselage portions (110,120), and a lower deck (108) extending within the first fuselage portion (110). The upper deck (106) can include a first passenger portion (107) and the lower deck (108) can include a second passenger portion (109), a cargo portion, or a second passenger portion and a cargo portion.
