Abstract: A blade wheel of a turbomachine, which blade wheel has a multiplicity of blades which are suitable and provided for extending radially in a flow path of the turbomachine, wherein the blades form a blade entry angle and a blade exit angle. Provision is made whereby the blade wheel forms N blocks of blades, where N?2, wherein the blades of a block have in each case the same blade entry angle and the same blade exit angle, and the blades of at least two mutually adjacent blocks have a different blade entry angle and/or a different blade exit angle. According to a further aspect of the invention, partial gaps that the blades form in relation to an adjacent flow path boundary are varied in mutually adjacent blocks.

Abstract: A structural subassembly for a compressor of a turbomachine, which has: a stator with a multiplicity of guide blades which extend in a flow path of the turbomachine, wherein the guide blades have an axis of rotation and are designed to be adjustable in terms of their stagger angle; an inner flow path boundary, which delimits the flow path through the turbomachine radially at the inside; and an outer flow path boundary, which delimits the flow path through the turbomachine radially at the outside. Here, the guide blades have first partial gaps with respect to the outer flow path boundary and/or second partial gaps with respect to the inner flow path boundary. Provision is made whereby the guide blades are arranged and formed such that the axes of rotation of the guide blades have a combined inclination both with respect to the axial direction and in a circumferential direction.
