Abstract
A gas turbine engine includes a main compressor section for compressing air, a main combustor section positioned downstream of the main compressor section, a main turbine section positioned downstream of the main combustor section, and a spool extending from the main compressor section to the main turbine section. A second turbine is fluidically connected to the main compressor section by a bleed passage. An electrical generator is mechanically driven by both the spool and the second turbine.
