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

摘要

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.

1. An aircraft structure part comprising:
a floor structure portion, a hull structure portion, and a connecting element, wherein the connecting element comprises: a rod attached, at a first end, to one of the hull structure portion and the floor structure portion; an attachment element, attached to the other of the hull structure portion and the floor structure portion, and provided with an opening in which a second end of the rod is mounted such that the rod can slide along its longitudinal axis; and an endstop element attached to the rod, arranged so as to engage with the attachment element when the hull structure portion tends to move away from the floor structure portion, so as to limit the sliding amplitude of the rod in the opening
