Abstract
The invention relates to a subassembly (10) of a turbomachine having a main axis (A) and comprising: - a plurality of blades (12) distributed angularly about the main axis and each extending radially with respect to the main axis; - an internal radial member (14) connected to an internal radial end (12a) of each blade (12); - an external radial member (16) connected to an external radial end (12b) of each blade (12), characterized in that the cross-section of each blade (12), along an axial plane passing through the main axis (A), comprises a chevron portion (20) whose tip (22) is directed axially. The invention also relates to a method for producing the subassembly (10). Figure for the abstract: Figure 1
