ABSTRACT:
The present invention is a BLISK airfoil heat treating apparatus and method for heat treating the leading and/or trailing edge section(s) of a BLISK airfoil using the BLISK airfoil heat treating apparatus. The apparatus comprises a pair of hingedly connected heat treating shells, each shell having a cavity for receiving an airfoil edge section requiring heat treatment. A resistive heating element is positioned with the shells to heat the cavities.
