Abstract

A compressor, in particular, of a turbomachine. The compressor comprises at least one blade ring and at least two ring segments, wherein the blade ring has at least two equally large ring segments. The compressor also comprises blades, which are arranged in the ring segments of the blade ring in such a way that a first number of blades is arranged in a first ring segment and a second number of blades is arranged in a second ring segment. The first number of blades is not equal to the second number of blades.

Claims (20)

1. A compressor comprising:

at least one first blade ring of a first compressor stage and formed of at least two ring segments being separable components,

blades which are arranged in the ring segments of the blade ring in such a way that a first number of blades are arranged in a first ring segment and a second number of blades are arranged in a second ring segment, wherein the first number of blades is not equal to the second number of blades;

a further blade ring of a further compressor stage and formed of at least two further ring segments being separable components with blades, wherein a number of blades of a first segment of the further ring coincides with said second number, and a number of blades of a second segment of the further ring coincides with said first number,

wherein a total number of blades in the at least one first blade ring is equal to a total number of blades in the further blade ring,

wherein the first ring segment of the at least one first blade ring and the second ring segment of the further blade ring are arranged opposite each other around an axis of rotation, and,

wherein the second ring segment of the at least one first blade ring and the first ring segment of the first blade ring are arranged opposite each other around the axis of rotation.

2. The compressor according to claim 1 , wherein at least one of:

the blades of the first ring segment are equidistant, or

the blades of the second ring segment are equidistant.

3. The compressor according to claim 1 , wherein an angular positioning of the first ring segment on the first blade ring is identical to an angular positioning of said second one of the further ring segments on the further blade ring.

4. The compressor according to claim 1 , wherein an angular positioning of the second ring segment on the first blade ring is identical to an angular positioning of said first one of the further ring segments on the further blade ring.

5. The compressor according to claim 1 , wherein at least one of:

the first blade ring has only two ring segments, or

the further blade ring has only two further ring segments.

6. The compressor according to claim 1 , wherein at least one of the blades of the first blade ring or the blades of the further blade ring are at least one of rotor blades or guide vanes.

7. The compressor according to claim 1 , wherein each of the compressor stages has a rotor blade ring and a guide vane ring.

8. The compressor according to claim 7 , wherein each guide vane ring is divided into at least two ring segments of the same size.

9. The compressor according to claim 7 , wherein each rotor blade ring is divided into at least four ring segments of the same size.

10. A fluid kinetic machine having a compressor according to claim 1 and a turbine.
