AIR-SEPARATION DEVICE AND CORRESPONDING INERTING DEVICE AND AIRCRAFT

摘要

The invention relates to an air-separation device comprising a casing (1, 2) housing a fibre bundle (3) forming a membrane, the longitudinal axis of the fibres being parallel to the longitudinal axis (A) of the casing (1, 2) and each of the two longitudinal ends of the fibre bundle (3) comprising a layer (8) of rigid material. The device also comprises a cylindrical jacket (7) disposed longitudinally around the fibre bundle (3) and a system for maintaining the fibre bundle (3) in the casing (1, 2), said system comprising a longitudinal end-stop mechanism (6) formed between an element of the casing (1, 2) and an element of a first longitudinal end of the fibre bundle (3) in order to block the movement of the fibre bundle (3) in relation to the casing (1, 2) in a direction parallel to the longitudinal axis (A) of the casing (1, 2). The aforementioned maintenance system also comprises a mechanical supporting member (9) between the casing (1, 2) and the jacket (7), and the second longitudinal end of the fibre bundle (3) is mounted in the casing (1, 2) such that it can move freely in translation in a direction parallel to the longitudinal axis (A) of the casing (1, 2).
