Shaft of a gas turbine engine

摘要

The shaft i.e. radial shaft (14), has a middle part (28) designed as a conical tube and made from carbon fiber composite material. Load conducting pieces (29) are made from metallic material and connected with the middle part over a positive sinusoid structure. End areas (27) of the middle part comprise sinusoid cross-section form. The conducting pieces comprise a central recess that ends into a radial channel, where the sinusoid structure comprises convex and concave areas. An intermediate area between outer contour of the conducting pieces and the end areas is filled with resin.
