Abstract

A blower system (400) for supplying pressurized air to an airframe of an aircraft comprises: an air inlet (422) for receiving air from an air source; an air outlet (426) for supplying pressurized air to an airframe; a blower compressor (420) in fluid communication with the air inlet and the air outlet, the blower compressor comprising a first rotor (420a) and a second rotor (420b), wherein the first and second rotors are independently rotatable in order to compress air received from the air inlet and deliver the compressed air to the air outlet; a variable transmission (430) comprising a first output (436) for driving the first rotor, a second output (438) for driving the second rotor, and first, second and third inputs (432, 434, 435); and first and second electrical machines (464, 465), each comprising an electric rotor and an electric stator, wherein: the first input of the variable transmission is configured to be mechanically coupled to a spool (440) of a gas turbine engine (10); the second input of the transmission is mechanically coupled to the electric rotor of the first electrical machine; the third input of the transmission is mechanically coupled to the electric rotor of the second electrical machine; and the electric stators of the first and second electrical machines are electrically connected to an electrical power management system (466) configured to control the supply of electrical power to the first and second electrical machines in order to control the speed of the first and second outputs of the variable transmission.
