Abstract
A hybrid engine having a gas turbine engine and an internal combustion engine, both engines driving a common drive shaft. The compressor delivers compressed air to the combustor and to an inlet of the internal combustion engine, the compressed air picks up heat from the internal combustion engine either from the combustion process or through a heat exchanger, and is delivered to the combustor. When the gas turbine engine is not operating by burning fuel, the heated compressed air from the internal combustion engine is used to maintain the shaft speed sufficient for starting the gas turbine engine without the need to bring the turbine engine up to speed prior to ignition. The apparatus and process of the present invention provides a hybrid engine that is light weight, fuel efficient, and with enough available power for high powered situations.
