Abstract
An electrically boosted cooling air system including a high pressure compressor; at least one cooling air supply line coupling the high pressure compressor with at least one of a high pressure turbine and a low pressure turbine; and an electrically powered centrifugal compressor fluidly coupled with the at least one cooling air supply line; wherein the electrically powered centrifugal compressor is configured to provide at least one of a pressure increase and a flow rate increase for cooling air supplied from the high pressure compressor.
