초록

A technique is provided for operating a gas turbine engine that has a combustor with a primary stage and one or more other stages and a first compressor providing an air flow to the combustor. This technique includes driving a variable load device with the rotating shaft of the gas turbine engine and sensing pressure of the air flow and an engine speed. In response to a decrease in loading of the engine by the variable load device: selectively bleeding the air flow as a function of the engine speed and regulating temperature in the primary stage of the c...

청구항

What is claimed is: 1. A method, comprising: driving a variable load device with a rotating shaft of a gas turbine, the gas turbine engine including a combustor with a primary stage and one or more other stages, and a first compressor providing an airflow to the combustor; varying fuel supplied to the combustor to provide a desired combustion zone temperature for the primary stage as engine loading by the variable load device changes; determining an engine overspeed in response to a decrease in the engine loading; and modulating a nonzero degree of blee...
