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.
