An arrangement for use in conjunction with aircraft arrester devices of the kind which comprise upper and lower, essentially horizontal edge elements (1 and 2), which edge elements are connected together by essentially vertical transverse elements (3) by means of coupling devices (5), for the purpose of protecting the transverse elements against the absorption of moisture, with an associated weight increase and rigidity at sub-zero temperatures. Each transverse element (3) is enclosed by a hose- or stocking-like protective sleeve (7), which on the one hand is so arranged as to interact in a sealing fashion at its ends with adjacent parts of the arrester device in such a way that water and moisture are prevented from finding their way into the element, and on the other hand is executed from a semi-permeable material of a kind, such as GoreTex TM , which is impermeable to water, but allows water vapour to pass through, so that any moisture which, in spite of every precaution, has managed to be absorbed by the transverse element (3), can evaporate into the surroundings. |
