Abstract
On a low-pressure turbine shaft made of fiber-composite material, the connection to the metallic driven protrusion or the driving protrusion (1), respectively, is made via an adapter (3) formed onto the latter, with pylons (6) extending beyond the circumferential area of the latter and on which the fibers (4) are deflected and guided in accordance with the fiber orientation in the fiber-composite material, enabling high torsional forces to be transmitted via the small connecting zone.
