Abstract

A compressor blade having a forward and rearward swept profile and a gas turbine including the compressor blade are provided. The compressor blade includes an airfoil including stacked sections having a predetermined thickness formed in a form of a closed curve, which connects a concave curve and a convex curve, extending in a radial span between a hub and a shroud, extending in a direction of a chord line between a leading edge and a trailing edge, and extending in a thickness direction between a pressure surface and a suction surface, wherein the airfoil is formed with sections having a predetermined thickness stacked to be inclined in a radial direction, and includes a swept profile formed such that the leading edge and the trailing edge are inclined forward or rearward of the chord line, and the swept profile includes a first area swept rearwards from the hub, a second area swept forwards from a position opposite to the first area to the shroud, and a third area that is not swept and is located between the first area and the second area.
