Abstract
A turbojet engine and a method for its operation which reduces NOx emissions, improves engine thermal efficiency, increases thrust and helps prevent engine performance deterioration. The turbojet engine includes two series of water injection nozzles which inject an atomized water stream into the compressor of the turbojet engine prior to the low pressure portion of the compressor and the high pressure portion of the compressor. The water injection nozzles that provide the atomized water stream to the low pressure portion of the compressor may be selectively disabled to inhibit water from being fed into the low pressure portion of the compressor based upon various criteria, such as the current atmospheric conditions.
