Abstract
A compressor rotor blade (1) includes a rotor blade (2), a platform (3) that adjoins the rotor blade (2) and blade footing (4) that adjoins the platform (3). The rotor blade (4) is embodied so as to be massive, without an internal cooling system, and exhibits a leading and a trailing edge (5, 6), a suction and a compression side, as well as a blade tip (7). The compressor rotor blade (1) is distinguished by virtue of the fact that the rotor blade (2) of the compressor rotor blade (1) exhibits a recess (8) on the trailing edge (6) of the blade tip (7).

A compressor rotor blade comprising:
- a blade footing;
- a platform;
- and
- a massive rotor blade without an internal cooling system, the massive rotor blade including a free blade tip, a leading edge, a trailing edge, a compression side, a suction side, and a recess on the free blade tip that extends to the entirety of the trailing edge;
- wherein the blade tip of the rotor blade includes a slope on an egress side toward the trailing edge of the blade;
- and
- wherein the slope assumes an angle (α) of 20° to 60° to the trailing edge of the compressor rotor blade.
