820,337. Gas turbine plant. BATHURST, G. B. April 10, 1956 [Jan. 11, 1955], No. 860/55. Class 110 (3). [Also in Group XXXIII] A radial flow gas turbine in which the rotor blades are arranged around the periphery of a compressor impeller has the rotor blades and the compressor impeller connected to a common hollow shaft through which fuel is fed to a series of nozzles in an annular combustion chamber, the air to support combustion entering the turbine casing through an air intake at the centre. The radial flow turbine, Fig. 3, comprises a centrifugal compressor 35 mounted on a hollow shaft 32 surrounding the hollow turbine shaft 20 and driven thereby through differential gearing 33. Air enters the opening 30 in the turbine front plate 22 and is burnt with fuel supplied through the shaft 20, chamber 36 and ducts 37 in an annular combustion chamber 40. A number of forms of differential gearing for connecting the turbine and compressor rotors are described.
