A combustion chamber liner having a layer of refractory material, a layer of metallic material, means to adaptably fix the layer of refractory material to the layer of metallic material and a means for internally cooling the liner. The means to adaptably fix the layer of refractory material to the layer of metallic material allows both layers to expand and contract separately without risk of damaging the liner because of different thermal expansion rates. The means for internally cooling the liner allows the liner to operate at higher temperatures and increases the useful life of the liner.

A combustion chamber liner having an internal cooling layered assembly comprising: first layer means of refractory material, said first layer being substantially impervious and having a first thermal expansion rate; second layer means of porous material, said second layer being structurally adaptable; third layer means of heat transfer members, said third layer also having paths for coolant to flow through; and fourth layer means of metallic material having a second thermal expansion rate and coolant passage means passing through said fourth layer means from a first side to an opposite second side proximate said third layer means whereby coolant can enter the liner through said coolant passage means into said third layer means to internally cool the liner so as to withstand high temperature and said second layer means allows said first and fourth layer means to expand at different thermal expansion rates with substantially no risk of damage to the liner from said different expansion rates.
