Abstract
A gas turbine power plant, such as a gas turbine engine for a motor vehicle, having a gas turbine, a combustor for producing hot gas to drive the turbine, and an air compressor for furnishing compressed air to the combustor. A heat exchanger, such as a rotary regenerator or a cross-flow recuperator, is located between the air compressor and the combustor for heating air by exhaust gas from the turbine before the air enters the combustor. The air leaving the exit of the heat exchanger decreases in temperature in a direction from one end of the exit to the other. A plurality of separate ducts conduct air from successive areas along the length of the heat exchanger exit to corresponding successive regions along the length of the combustor, the air temperature being lower in each succeeding duct. The lowest temperature air is conducted to the region containing a forward portion, e.g., the head, of the combustor, and air of progressively higher temperature being ducted to successive regions closer to the exhaust end of the combustor.
