Abstract
A method of developing a suggested blend repair to an airfoil includes the steps of: (a) storing history with regard to a particular airfoil in a particular engine; (b) taking information with regard to new damage to the particular airfoil; (c) reaching an initial blend recommendation based upon step (b); (d) assessing whether the initial blend recommendation of step (c) would be appropriate to repair the new damage based upon a consideration of steps (a)-(c); and (e) reporting a final blend recommendation. An airfoil repair recommendation system is also disclosed.

A method of developing a suggested blend repair to an airfoil comprising the steps of:
- (a) storing history with regard to a particular airfoil in a particular engine;
- (b) taking information with regard to new damage to the particular airfoil;
- (c) reaching an initial blend recommendation based upon step (b);
- (d) assessing whether the initial blend recommendation of step (c) would be appropriate to repair the new damage based upon a consideration of steps (a)-(c);
- and
- (e) reporting a final blend recommendation.
An airfoil repair recommendation system comprising:
- a controller having a receiver, an evaluation module, and a repair module, the controller including at least a non-transitory memory and a processor;
- the receiver including an input configured to receive information with regard to a particular airfoil, and an output communicatively coupled to said evaluation module;
- the evaluation module including instructions configured to cause the controller to analyze the received information utilizing an algorithm and determine whether a blend may be recommended;
- and
- the repair module including instructions configured to cause the controller to develop a final recommendation with regard to the airfoil being considered and to cause the controller to transmit that final recommendation to a location of the airfoil.
