ABSTRACT:
A supporting device is disclosed for an arrangement of articulated elements such as a fin-rudder arrangement, wing-trailing edge flap arrangement, and the like, for aircraft or watercraft. The disclosure more particularly relates to the cover for the gap existing between the two articulated elements. There is disclosed an arrangement of levers and bearing points which allow the cover to maintain a constant length and approximately constant curvature over its length as the two elements move relatively to each other. The arrangement of the disclosure eliminates corners and folds in the elastic cover without also requiring parts protruding beyond the elastic cover and without requiring high forces to deflect the cover.
