Abstract
A compressor comprises: a rotor including a hub and a blade provided on an outer peripheral surface of the hub; and a casing surrounding the rotor so as to face a tip of the blade across a gap. Provided that the gap between the tip of the blade and the casing has a size t0 at a leading edge of the blade, the gap between the tip of the blade and the casing has a size larger than t0 in at least a partial range downstream of the leading edge in an axial direction of the rotor.

A compressor, comprising:
- a rotor including a hub and a blade provided on an outer peripheral surface of the hub;
- and
- a casing surrounding the rotor so as to face a tip of the blade across a gap,
- wherein
- provided that the gap between the tip of the blade and the casing has a size t0 at a leading edge of the blade, the gap between the tip of the blade and the casing has a size larger than t0 in at least a partial range downstream of the leading edge in an axial direction of the rotor and
- wherein
- in a size distribution of the gap between the tip of the blade and the casing from the leading edge to a trailing edge of the blade, a maximum value tMAX of the gap satisfies 1.1t0≤tMAX≤1.5t0.
