Abstract:
1. A wall structure constituting a portion of a containment structure for heated combustion gases of a rocket engine and which are therefore exposed to thermal loading, said wall structure comprising: at least two layers including a first layer and a second layer, said first layer and said second layer being located closer to the heated combustion gases than said first layer; said first layer containing longitudinally running cooling channels configured to accommodate cooling fluid passing therethrough; said at least two layers being bonded together and thereby creating an interface between adjacent surfaces thereof so that heat is conducted from the second layer to the first layer, said interface being radially interiorly located relative to said cooling channels in said first layer; and said at least two bonded-together layers together establishing a load bearing wall structure for a rocket engine in which significant portions of structural loads imposed thereupon are distributed to, and borne by each of said at least two bonded-together layers.
