ALL MOVING BLADE GAS TURBINE

摘要

PURPOSE:To miniaturize a size and lighten a weight by outwardly fitting and supporting rotatably an outside turbine shaft provided with an axial flow com pressor outside moving blade group and a turbine outside moving blade group, on the outside of a turbine shaft provided with an axial flow compressor moving blade group and a turbine moving blade group. CONSTITUTION:A turbine shaft 3 provided with an axial flow compressor mov ing blade 2 group and a turbine moving blade 8 group is provided in the central major shaft direction of a fixed cylinder 1, and supported on the front and rear parts of the fixed cylinder 1. An outside turbine shaft 6 provided with an axial flow compressor outside moving blade 4 group and a turbine outside moving blade 5 group is outwardly fitted and supported rotatably/on the outside thereof. And a combustor 7 is arranged between the compressor outside moving blade 4 and the turbine outside moving blade 5. It is thus possible to double the relative speed between the moving blades in a turbine and a compressor. And since respective flow passages can be shortened, it is possible to miniaturize a size and lighten a weight so as to provide high performance.
