Arrangement of blades in a blade ring based on a primary crystal orientation

摘要

Disclosed is a blade ring (1) of a turbomachine, which comprises a plurality of blades (S ₁ , S ₂ , ..., S _i , S _{i + 1} , ... S _n-1 , S _n ), each completely or partially made of a monocrystalline material. The plurality comprises two adjacent blades (S ₁ , S _n ) whose primary crystal orientations (α) have an absolute difference greater than 10 times an absolute difference in the primary crystal orientations of at least one other pair of adjacent blades of the plurality. Also disclosed is a turbomachine with a blade ring.
