Befestigung einer thermischen Isolationsstuktur

摘要

A fastening for a thermal insulation structure on the airframe of an aircraft, the insulation structure consisting of a large number of panels (6) which are resistant to strong heating, are mechanically robust and, if necessary, are provided with an additional joint seal, having a plurality of fastening points (1, 2, 3) per panel, which fastening points (1, 2, 3) are spaced apart from one another and produce a positively locking connection between the insulation structure and the airframe. The fastening has a first fastening point (1) which does not permit any movement, or permits at most limited rotational movement of the panel (6) about an axis which is at right angles to the airframe surface (5), a second fastening point (2) which permits limited, linear displacement of the panel (6) parallel to the airframe surface (5), and at least one further fastening point (3) which permits limited displacement of the panel (6) in all directions. The first fastening point (1) is designed as a self-locking plug-in and snap-action connection which is detachable from the panel surface and has a connecting bolt (8), a connecting element which holds this bolt, and a spring element which locks these two parts. All the other fastening points are designed as plug-in connections, with the same insertion direction for all the fastening points.
