An aircraft blower system comprising:
- a transmission including (i) at least two traction drives, and (ii) a planetary gearbox disposed between the at least two two traction drives and mechanically coupled to each of the at least two two traction drives;
- and
- a compressor mechanically coupled to the planetary gearbox, the aircraft blower system having a forward configuration in which the compressor is configured to be driven by a gas turbine engine via the transmission, the transmission including a first toroidal continuously variable transmission providing control over a selectively variable rate at which the compressor is driven;
- wherein the aircraft cabin blower system is configured to operate in a reverse configuration including a supply of pressurised gas being supplied to the compressor, and the compressor acting as a turbine and driving one or more shafts of the gas turbine engine via the transmission.
