A combustion chamber liner has three layers; a first ceramic layer, a second filamentary steel wool type layer and a third metallic layer. The interior of the liner is cooled by passages in the third layer and emergency or failure activated cooling occurs in a damaged area in the first layer. Sensor means can be placed in the liner or externally of the liner to detect changes in the coolant flow or pressure and thereby detect a failure in the liner.

A failure activated emergency cooled combustion chamber liner for use in a combustor having a combustion chamber wall and a combustion zone, the liner having a plurality of liner panels, each panel comprising: first layer means of refractory material adjacent the combustion zone of the combustor, said first layer means being substantially impervious; second layer means of porous material adjacent said first layer means, said second layer means having a coolant reservoir means for storing and transporting a supply of coolant, the coolant being relatively pressurized relative to gases in the combustion zone, said coolant reservoir means having substantial access to said first layer means adjacent said second layer means; third layer means of metallic material adjacent said second layer means, said third layer means having coolant passage means therethrough for circulating a coolant through said third layer means into said coolant reservoir means such that a substantially constant supply of relatively pressurized coolant is maintained in said coolant reservoir means whereupon in the event of damage such as a fracture or void through the first layer means, the stored coolant in said coolant reservoir means will be directed to and through the fracture or void in said first layer means into the combustion zone thereby cooling the combustion chamber liner and preventing further damage to the liner; and means for mounting the panels to a combustion chamber wall to thereby protect the chamber wall from heat in the combustion zone.
