The disclosure herein relates to a part of an aircraft structure including a portion of a floor structure and a portion of a hull structure, connected to one another by a connecting element. In accordance with, the disclosure herein the connecting element includes a flexible cable fixed at one of the ends thereof to the portion of a floor structure and fixed at the other, second of the ends thereof to the portion of a hull structure. When the connection between the portion of a floor structure and the portion of a hull structure is subjected to tensile load, the flexible cable makes it possible to meet the standards of resistance to forward accelerations of the aircraft. When the connection is subjected to compressive load, the flexible cable relaxes and bends, which limits the requirements of withstanding compressive stresses and therefore the weight of the connecting element.

Flexible connection between the floor structure and the hull structure of an aircraft

An aircraft structure part comprising a floor structure, a hull structure, and a connecting element. The connecting element comprises a rod attached, at its first end, to one of the hull and the floor; an attachment element, attached to the other of the hull and the floor, and provided with an opening in which the second end of the rod is slidably mounted; and an endstop attached to the rod so as to engage with the attachment element, to limit the sliding amplitude of the rod in the opening. When the connection between the floor and the hull is loaded in tension, the endstop makes it possible to comply with the standards for withstanding acceleration towards the aircraft front. When the connection is loaded in compression, the rod slides freely in the opening, which limits the constraints of withstanding compressive stresses, reducing the weight of the connecting element.
