Abstract
The method for forming a turbofan mixer comprises providing a single monolithic and generally flat annular sheet metal blank, providing a die surface substantially corresponding in shape to a turbofan mixer shape, positioning the blank with reference to the die surface, and forcing the blank against the die surface to transform the blank into a monolithic turbofan mixer.
