摘要： There is provided a blower system 400 for providing air to an airframe system 450, comprising a rotor 410 configured to be mechanically coupled to a spool 440 of a gas turbine engine 10, wherein the rotor 410 is configured to: in a blower mode, be driven to rotate by the spool 440 to discharge air to an airframe discharge port 426 for supply to an airframe system 450; and, in an engine drive mode, receive air from an external air source 470 via an impingement port 424 that is configured to direct the received air onto the rotor and thereby drive the rotor to rotate to drive the spool 440 to.
