Stacked-Disk Combustor
Materials chosen for strength rather than thermal conductivity. Stacked washerlike disks accommodate built-in coolant passages while providing combustion zone of ideal shape. Fuel flows through coolant passages where preheated before entering combustion zone through passages in disks. Eight coolant passages in cross section, although number in particular application determined by required rate of flow of fuel and pressure drop. Combustion chamber operates for greater efficiency at pressures and temperatures higher than those of conventional tube-wall combustion chamber.
