  • Rotating diffuser in centrifugal compressor
    Patent number: 11346366
    Abstract: A centrifugal compressor includes a shaft defining an axis, an impeller mounted to the shaft for rotation about the axis, and a diffuser section including a first wall, a second wall, and an opening defined between the first wall and the second wall. The opening of the diffuser section is arranged in fluid communication with the impeller. The first wall is rotatable about the axis and rotation of the first wall about the axis is mechanically driven.

  • Blade for axial compressor rotor
    Patent number: 9908170
    Abstract: A blade for a compressor rotor including a blade root at a first end of the blade connected to the compressor rotor and a blade tip extending from second end of the blade. The blade tip extends up to 20% of a span of the blade from the second end towards the first end. The blade tip is disposed such that a first segment of the blade tip defines a positive dihedral angle and a second segment of the blade tip defines a negative dihedral angle. The positive and negative dihedral angles defining a twist of the blade tip relative to the face of the blade, wherein the blade remains untwisted along the span from outside of the blade tip.

  • Blade for Axial Compressor Rotor
    Publication number: 20150219115
    Abstract: A blade for a compressor rotor comprises a blade root at a first end of the blade extending from a rotor body of the compressor, and a blade tip at a second end of the blade. The first end and the second end are disposed on a span of the blade. The blade root and the blade tip define a face of the blade between them. The blade tip comprises a first extremity and a second extremity. The blade tip is disposed such that a first segment of the blade tip defines a positive dihedral angle with the face of the blade. The first segment extends from a first point in the blade tip to the first extremity of the blade tip. A second segment of the blade tip defines a negative dihedral angle with the face of the blade. The second segment extends from a second point in the blade tip to the second extremity of the blade tip.
