Gas-cooled flameholder assembly
This patent describes a gas turbine engine. It comprises an air compressor; an outer casing extending downstream from the compressor; a core engine including a turbine joined to the compressor, the core engine being disposed in the casing and defining therewith a bypass duct for channeling a first portion of air from the compressor around the core engine and for receiving a second portion of air from the compressor for mixing with fuel and generating combustion gases for driving the turbine and the compressor, the gases being dischargeable from an aft end of the core engine; an afterburner disposed downstream of the core engine and including: a combustor liner, a flameholder assembly disposed upstream of the liner and downstream of the core engine, the assembly including a flameholder, and means for cooling the flameholder by channeling only noncombustible gas to the flameholder, the noncombustible gas being a first portion of the combustion gases.
