Combustion system for a gas turbine engine with variable airflow pressure actuated premix injector

Abstract

The present disclosure provides a turbogenerator system having a turbine mounted for rotation on a shaft, a motor/generator coupled with the shaft for rotation therewith. A combustor for combusting fuel and compressed air to generate combustion gases for rotating the turbine is provided as well as a compressor providing compressed air, and an injector having at least one opening to admit the compressed air from the compressor. The injector may be connected to the combustor to inject fuel and compressed air into the combustor. A piston slidably covering the at least one opening in the injector provides a variable entry to the compressed air, and a pressure actuator associated with the piston and responsive to pressure in the combustor is used for determining the size of the variable entry. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
