    • An aircraft fuselage structure which is constructed from a plurality of shells which are joined together is disclosed. Each shell forms part of the aircraft fuselage and comprises a support structure and a skin which is arranged on the latter and outwardly seals the aircraft fuselage in a compression-proof manner. The aircraft fuselage structure comprises an upper and side shell and a lower shell, of which the lower shell has a radius which is essentially significantly larger than the radius of the upper and side shell. The upper and side shell and the lower shell are joined together at transition regions extending in the longitudinal direction of the aircraft. The support structure of the lower shell is designed in terms of its strength in such a manner that it is capable of absorbing the internal pressure loading of the lower shell without the use of a main crossmember.
    • 描述了一种飞机机身结构,其由多个连接在一起的壳体(11,12)构成,每个壳体形成飞机机身(10)的一部分并且包括支撑结构(13,13a,14,14a)和 (15,16),所述表皮(15,16)布置在所述表皮上并且以防压方式向外密封所述飞机机身(10)。 根据本发明,飞机机身结构包括上壳体和侧壳体(11)和下壳体(12),其下壳体(12)具有半径(R2),该半径(R2)基本上明显大于半径 ),所述上壳体和所述侧壳体(11)以及所述下壳体(12)在沿所述飞机的纵向方向延伸的过渡区域(18,19)处连接在一起,并且所述支撑结构 (12)的下部壳体(13,13a)在其强度方面设计成能够在不使用主横梁的情况下吸收下壳体(12)的内压负荷。
