Abstract
An apparatus is provided for separating components of a brazed vane assembly by preheating the assembly to a temperature below the solidus of the base metal of the vane assembly and above the liquidus of the braze, then maintaining such temperature while separating the airfoil from the platform by pulling/pushing the airfoil and platform apart.
Claims6
Apparatus for separating a platform from an airfoil of a gas turbine engine brazed vane assembly comprising:
- a heating means for preheating the assembly and maintaining the assembly at a predetermined temperature during the separation of the platform from the airfoil;
- a first fixture means for gripping the inner platform of the vane assembly and a second fixture means for gripping the outer platform of the vane assembly;
- a motion system for applying opposing motion and force to the first and second fixture means and to the platforms gripped thereby to separate the airfoil from the platform.
