Abstract

A system for removably mounting a thermal insulation blanket to a structure such as a launch vehicle exterior surface, includes a blanket formed of a layer of batting with a substantially rigid frame positioned against one side, and a cover (preferably fabric) surrounding the batting layer. The cover holds the frame in place on the surface of the batting. Preferably, the blanket is quilted. For space launch applications, the batting, cover, and quilting thread are ceramic fiber materials suitable for high temperature use. Fasteners are mounted on the frame and extend outward from the cover. Corresponding mating fasteners are mounted on the structure in an arrangement so as to be positioned to engage with the fasteners extending from the blanket cover. A flat or curved blanket can be provided with a frame material that can be shaped to the desired curve.

Claims

1. A system for mounting a thermal insulation blanket to a structure wherein the blanket comprises:

a batting layer;

a substantially rigid frame positioned against the side of the batting layer which is adjacent the structure when the blanket is mounted thereto;

a cover surrounding said batting layer and said frame;

fasteners mounted on said frame and extending from said cover;

and further comprising mating fasteners mounted on said structure in an arrangement so as to be positioned to engage with said fasteners extending from said cover.

2. The blanket of claim 1 wherein said frame comprises titanium tubing.

3. The blanket of claim 1 wherein said cover includes a woven ceramic material.

4. The blanket of claim 3 wherein said frame is recessed within said batting layer.

5. The blanket of claim 3 wherein said blanket is substantially rectangular, and the fasteners include fasteners mounted near the comers of said frame.

6. The blanket of claim 5 further comprising a cross brace joining two opposing sides of said frame.

7. The blanket of claim 6 wherein said fasteners include quick-release fasteners.

8. A thermal insulation blanket adapted for removable mounting to a structure comprising:

a batting layer;

a substantially rigid frame positioned against the side of the batting layer which is adjacent the structure when the blanket is mounted thereto;

a cover surrounding said batting layer and said frame; and

fasteners mounted on said frame and extending outward from said cover.
