T55 Compressor Rotor Turn Time Reduction -- Phase I

Abstract

The T55 jet engine used in the CH-47 Chinook helicopter contains either the T712 or the T714 compressor rotor. After a time, these compressor rotors need to be rebuilt to meet the original equipment manufacturer's (OEM) specifications. Corpus Christi Army Depot's (CCAD) current rebuilding process requires numerous set-ups, which results in a turn-around time of 15 to 16 hours to completely refurbish one compressor rotor. CCAD is in need of a grinding center to reduce the cycle time, and due to a change in compressor rotors from the T712 to the T714, it also is in need of a grinding center that will accommodate the addition of a 17.5-inch shroud that is not present on the T712. The National Center for Defense Manufacturing and Machining (NCDMM) was requested to evaluate the current process and provide a grinding solution for CCAD that would eliminate the multiple set-ups and reduce the current cycle time to allow 4 to 5 assemblies to be ground each day.
