Abstract (en)

[origin: EP2090747A1] The part i.e. vane (10), has a sheet (60) that is made of material e.g. austenite phase memory alloy such as nickel copper alloy, fixed on a main part (15) and extended from a lower surface (30) to an upper surface (50) of the part so as to define a space (70) between the sheet and an upstream end (20) of the part. The sheet covers the end of the part, and the material of the sheet is deformed in a super elastic reversible manner in response to an impact by an outside body e.g. gravel, without damaging the part. An independent claim is also included for a method for fabricating a part of a turbomachine.
