An aircraft cabin blower system (100) comprises a transmission (110) configured to receive mechanical power from a gas turbine engine in the form of a first transmission input (114); and an electrical circuit comprising a first electrical machine (116), a second electrical machine (120), and a power management system (122), wherein, when operating in a blower mode, the first electrical machine is configured to receive mechanical power from the gas turbine engine and act as a generator to provide electrical power to the power management system, and the second electrical machine is configured to act as a motor providing mechanical power to the transmission in the form of a second transmission input (118), the second electrical machine being driven by electrical power from the power management system. An output of the transmission is configured to drive a cabin blower compressor (102) when operating in the blower mode, a speed of the output of the transmission being determined by a function of a speed of the first and second transmission inputs.
