Turbomachine with blades having blade tips lowering towards the trailing edge

A turbomachine, comprising:

• a rotor, which is mounted rotatably around its longitudinal axis in a stator, and which has at least one row of rotating blades, which is formed by a plurality of rotating blades,
• the stator having at least one abradable layer,
• each rotating blade of the plurality of rotating blades having blade tips comprising a front blade tip region, at least one middle blade tip region, and a trailing blade tip region that are lowered radially inward in sections from a leading edge of the rotating blade to a trailing edge of the rotating blade,
• wherein, during operation, the front blade tip region and the at least one middle blade tip region of each of the rotating blades runs into, and is in contact with, the at least one abradable layer, and the trailing blade tip region is radially distanced from the at least one abradable layer, forming a radial gap, whereby formation of a parasitic gap is prevented,
• wherein the front blade tip region extends from the leading edge of the rotating blade to the at least one middle blade tip region in a direction towards the trailing edge of the rotating blade,
• wherein the trailing blade tip region extends from the at least one middle blade tip region to the trailing edge of the rotating blade, and
• wherein radial dimensions of the front blade region are greater than radial dimensions of the at least one middle blade tip region, and the radial dimensions of the at least one middle blade tip region are greater than radial dimensions of the trailing tip region.
