Improved Fabrication Methods of Jet Engine Rotors

Abstract

The report summarizes the program to establish and demonstrate manufacturing methods for fabricating jet engine rotors. The report contains: (1) mechanical property data on inertia welded Inco 718, U-700 and Ti 6Al-4V; (2) inertia welding parameters for Inco 718 and U-700; (3) metallographic and nondestructive inspection results of inertia welded Inco 718; (4) an analysis of transient temperature gradients in inertia welding; (5) mechanical property data on cold rim formed Inco 718 cross rolled plate; (6) shear forming data for cross rolled plate; (7) results of weld acceptance testing of the Caterpillar Model 400 inertia welder; (8) results of inertia welding TF39 Stages 14-16 Compressor rotor; (9) engine test results of various fabricated rotors; and (10) an overall evaluation of the program to develop and demonstrate manufacturing methods to fabricate compressor rotors from cross rolled plate and joined by inertia welding.
