Abstract:

A curved slot is formed between an internal cavity of an airfoil and the trailing edge thereof by temporarily deflecting the airfoil trailing edge portion toward the suction side thereof, forming a straight slot in the trailing edge portion while it is in the deflected position, and releasing the deflecting pressure to allow the trailing edge portion to spring back into an unstressed condition so as to thereby curve the slot within the trailing edge portion. Further curvatures may be effected by subsequent reformation of the trailing edge portion toward the pressure side of the airfoil.
