Abstract

A gas turbine of the type having a plurality of axial compressor stages. The entire unit is mounted in a tubular support including coaxially mounted compressor and turbine blades for rotation independent of one another. The compressor blades are mounted in a ring radially inwardly of the ring of turbine blades, a combustion chamber is disposed radially inwardly of the ring of combustion ring. The gas first flow through the ring of compressor blades and then through the ring of turbine blades.

Claims

1. A rotating machine driven by fluid comprising a housing defining an envelope of revolution opened at first and second ends, a multiplicity of contiguous coaxial rotor wheels within said envelope, supporting means for rotatively supporting each wheel, each wheel comprising a first series of annular blades and a second series of peripheral blades, the heights of the blades of the first series progressively decreasing from one wheel to the next along a direction extending from said first end to said second end of the envelope, and the second series of blades of the wheels being of a progressively increasing height from one wheel to the next relative to the same direction, and guiding means for guiding the fluid that passes through the first series of blades of the wheels along said direction from said first end to said second end in order to direct it to face the second series of blades of the wheel at said first end, said guiding means comprising a combustion chamber fixed and housed within said supporting means.

2. A rotating machine according to claim 1, wherein the blades of the first series and the blades of the second series of a rotor wheel are hollow, and further comprising means for providing a fluid connection between the inside of a blade of the first series with the inside of a blade of the second series.

3. A rotating machine according to claim 1, wherein a rotor wheel comprises in addition to a first series of blades adjacent supporting means and a second series of blades, a third series of peripheral blades.

4. A rotating machine according to claim 1, wherein the blades of the first series are compressor blades and the blades of the second series are turbine blades, and one wheel supports two series of compressor blades and one series of turbine blades.

5. A rotating machine according to claim 1 wherein each of the wheels is supported by a gas bearing.

6. A rotating machine according to claim 1 wherein each of the wheels is supported by a hydrostatic bearing.
