Abstract

A cabin blower (100) for an aircraft (50), the system comprising: a cabin blower compressor (110); an electric machine (131); and a controller (133) configured to control the cabin blower system (100) so that: in a cabin blower mode of operation, the cabin blower compressor (110) is driven by power extracted from one or more spools (26, 27) of a gas turbine engine (10) of the aircraft (50) and provides a flow of air to a cabin of the aircraft (50). The controller (133) may be further configured to control the system (100) so that: in a rotor bow mitigation mode of operation, the cabin blower compressor (110) is driven by the electric machine (131) using electrical power from an electrical power source (134) and provides a flow of air through a core of the gas turbine engine (10) to remove heat from the core. A method (60) of operating a cabin blower system (100) of an aircraft (50) is also provided.
