ABSTRACT:
A gas turbine unit comprising an expansion turbine, a compressor and a turbine engine arranged in sequence on a common shaft. The rotor element of the expansion turbine comprises fan blades having a straight non-curved profile. Guide vanes are provided upstream of the expansion turbine to form a throttling device for controlling the flow of air to the expansion turbine. The guide vanes are adjustable relative to the blades of the expansion turbine to deflect the air to vary the throttling effect to cause the expansion turbine to operate alternately as a compressor and a turbine in response to the adjustment of the guide vanes.
