Hollow fan blade for turbomachine and method for manufacturing such a blade

The method involves initially forging a titanium alloy, and placing several inserts in the alloy to manufacture a mono-block blower blade (1) equipped with several inserts. The inserts are then eliminated from the alloy by chemical dissolution of these inserts, in order to obtain several recesses (1...

Zusammenfassung:	The method involves initially forging a titanium alloy, and placing several inserts in the alloy to manufacture a mono-block blower blade (1) equipped with several inserts. The inserts are then eliminated from the alloy by chemical dissolution of these inserts, in order to obtain several recesses (16) in the blower blade. The gaps extend radially along a center line (18). An independent claim is also included for a mono-block hollow blower blade.
