Thermally insulative attachment

摘要

A thermally insulative component is a thermal barrier panel attached to a rigid structural member with means for attaching the insulative component to an external structure. The connection between the structural member and the thermal barrier panel is mechanically compliant to minimize intercomponent stress build up during operation. The thermal barrier panel is a fiber wrapped ceramic oxide foam insulating structure.

主权项

1. A thermally insulative component for mounting on an external body comprising:
a thermal barrier panel comprising a fiber-wrapped ceramic foam panel; a rigid structural member with a first side including means for mounting the insulative component to the external body, and a second side opposite the first side and facing the thermal barrier panel; an air space defined between the second side of the rigid structural member and the thermal barrier panel, and separating the thermal barrier panel from the rigid structural member; a plurality of substantially U- or V-shaped mechanically compliant connections extending through the rigid structural member, bridging the air space at regular intervals, and securing the thermal barrier panel to the rigid structural member while absorbing relative thermal and mechanical deformations of the rigid structural member and the thermal barrier panel; and a braze alloy layer abutting the first side of the rigid structural member, and securing the mechanically compliant connections to the rigid structural member.
