A gas turbine fan jet has a pair of contra rotating fans each of which is driven by an electrical induction motor 3, 5 and each is governed by a controller 2,7. A power generator 8 supplies electricity, which may be three phase, to the motors. The generator may be shaft driven by the turbine. Air is drawn in by the fans around and through the duct and flows over cooling vanes 10 in which are cooling channels Fig 2, 11. A moveable baffle or door 9 may regulate air flow over the vanes. The vanes may cool the compressor and turbine housing. The device seeks to increase fuel efficiency by replacing prior art mechanical gearboxes and drives to the fans by use of superconducting electrical motors and an adaptive learning intelligent control system.
