Abstract (en)
The blade (1) root (3) includes a recess (9) with an opening (10) having a closed edge lying in the partition surface (5). The root is T-shaped or double-T-shaped. It can be assembled into a shaft groove. The depth of the recess extends to the center of the root. The root has two opposite partition surfaces (5) with recesses constructed in them, leaving an internal wall. The closed edge of a recess is essentially rectangular with height A and width B. The closed edge is alternatively generally-circular.
