In order to accommodate differential expansion between thermal protection panels and a structure to be protected, the present invention provides a stand-off for holding the panels, the stand-off comprising a first portion allowing displacements to take place in a first direction and a second portion allowing displacements to take place in a second direction. Each of the two portions also presents a high degree of stiffness in a direction corresponding to tear-off and crushing forces applies to the panels. The stand-off is made as a single piece having first and second recesses formed therein in order to make the first and second portions respectively in determined orientations so that the resulting stand-off allows displacements to take place in two distinct directions perpendicular to the tear-off and crushing directions.
A stand-off for holding a thermal protection panel on structure to be protected, wherein the stand-off comprises a first portion suitable for fixing to the structure to be protected, said first portion allowing displacements to take place in a first direction substantially parallel to the plane of the panel, and a second portion situated above said first portion and suitable for being connected to the panel, said second portion allowing displacements to take place in a second direction substantially parallel to the plane of the panel and perpendicular to said first direction, and wherein said stand-off presents stiffness in a third direction substantially perpendicular to the first and second directions,
