Brazing as a Fabrication Method when Manufacturing an Intermediate Compressor Case in Stainless Steel
2011 (Engelska)Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
Abstract [en]

Almost every industry of today, aviation industry included, focuses on reducing costs to remain competitive. Volvo Aero Corporation (VAC) manufactures high technology components for jet engines and is a collaborator in numerous commercial jet engine programs. One of these components is the Intermediate Compressor Case (ICC) which is located between the intermediate pressure compressor and the high pressure compressor and is a static, load carrying structure. Compressor structures in aircraft engines are generally cast and made in titanium. This project has investigated how the next generation ICC could be fabricated in the stainless steel 17-4PH by brazing in order to reduce manufacturing cost.The thesis aims to come up with a solution on how the ICC can be brazed. To achieve a successful brazing operation there are several factors to consider. Brazing filler metals, joint design, joint clearance, non-destructive testing and the complete brazing process with manufacturing solutions for the involved parts has been investigated in this thesis.A literature study of brazing methods, brazing filler metals, joint designs and furnace types was made in the beginning of the thesis work. Solutions for these stages were categorized in concepts and then selections were made with the aid of comparison tables and evaluation matrices.The conclusions drawn in this project are that brazing of the ICC is possible as long as the tolerances of the parts are accurately controlled and suggestions on how the tolerances can be controlled are presented in the thesis. The joint proposed is a modified butt-lap joint and the filler metal proposed is the nickel based Ni-613. The final concept advocates that no clearance except the work-pieces surface roughness should be used when brazing the ICC. Guidelines for improving the Technological Readiness Level at VAC are also included in the thesis.
