Abstract:
1. A section of aircraft fuselage, comprising: a body structure, circumferentially closed; and a floor connected to said body structure, the section is associated with a section reference frame defined by a longitudinal axis X, a lateral axis Y in a plane perpendicular to the longitudinal axis X oriented in a horizontal direction when the floor is horizontal and comprising a Z axis in a plane perpendicular to the longitudinal axis X oriented in a vertical direction when the floor is horizontal, wherein said body structure comprises: wherein each frame defines an obstacle-free interior width, at a floor level, known as a free frame passage l wherein the floor has at least two cross members, each of the cross members being parallel to the lateral axis Y and substantially in a frame plane and each of the cross members extending from a respective first end to a respective second end, wherein at every point of each free frame passage, a length L wherein a mounting surface of each cross member, at the first end and at the second end, is fixed to the body structure by an intermediate structural assembly, which connects the mounting surface of each cross member to the external skin and to at least one of the frames, and able to realize an individual embedding connection of each end of each cross member with the body structure, and wherein the intermediate structural assembly comprises a cornice, the cornice including a first core that connects to the at least two frames, the first core defining a first bearing surface on top of which the mounting surface of one of the first end and the second end is directly placed.
