Abstract
A multilayer thermal protection system includes a metallic substrate; a first ceramic layer; a bond coat layer attaching the first ceramic layer to the metallic substrate, wherein the first ceramic layer is applied by plasma spraying; at least one second ceramic layer attached to the first ceramic layer, wherein the at least one second ceramic layer includes monolithic ceramic elements adhesively attached to the first ceramic layer; and a ceramic adhesive layer attaching the at least one second ceramic layer to the first ceramic layer.
Claims20
A multilayer thermal protection system comprising:
- a metallic substrate;
- a first ceramic layer;
- a bond coat layer attaching the first ceramic layer to the metallic substrate, wherein the first ceramic layer is applied to the bond coat layer by plasma spraying;
- at least one second ceramic layer attached to the first ceramic layer, wherein the at least one second ceramic layer includes monolithic ceramic elements adhesively attached to the first ceramic layer;
- and
- a ceramic adhesive layer attaching the at least one second ceramic layer to the first ceramic layer.
A method for the production of a multilayer thermal protection system comprising:
- attaching the first ceramic layer using a bond coat layer on the metallic substrate, the first ceramic layer being applied to the bond coat layer using plasma spraying;
- and
- attaching at least one second ceramic layer on the first ceramic layer using a ceramic adhesive layer, wherein the at least one second ceramic layer includes monolithic ceramic elements adhesively attached to the first ceramic layer.
