Abstract:
1. A thermal protection apparatus comprising: a porous layer, having a void size of less than about 50 microns, and having an outer surface and an inner surface, directly attached to an inner structural member requiring thermal protection at said inner surface of said porous layer, and having a semi-permeable layer attached to said outer surface of said porous layer, said porous layer adapted to carry a flow of cooling fluid that is actively introduced into said porous layer, said porous layer including an inlet end and an outlet end, said inlet end being adapted to receive said flow of cooling fluid into said porous layer, and said outlet end being adapted so that most of said cooling fluid exits out of said outlet end after flowing along a substantial length of said porous layer, wherein said length is substantially parallel to a bond-line between said porous layer and said inner structural member.
