Abstract
A compressor, particularly a high-pressure compressor, of a gas turbine, particularly of an aircraft engine, includes at least one rotor and a number of blades (), which are assigned to the or to each rotor and which rotate together with the respective rotor. Each blade () is delimited, in essence, by a flow entry edge or leading edge (), a flow exit edge or trailing edge (), and by a blade surface (), which extends between the leading edge () and the trailing edge () while forming a suction side () and a pressure side. The leading edges () of the blades () are slanted at a sweep angle that changes with the height of the respective blade () in such a manner that the leading edges () comprise, in a radially external area () of the same, at least one forward sweep angle, a backward sweep angle or zero-sweep angle following in a radially external manner, and a forward sweep angle following, in a radially external manner, the backward sweep angle or the zero-sweep angle.
