Cover Structure Design of Titanium Alloy Based on the SPF/DB Process

Abstract

Five titanium alloy SPF/DB cover structures such as aircraft engine nacelle hatch, booster hatch, air conditioning hatch, pneumatic pump door are designed based on SPF/DB process. Use of SPF/DB and combination process such as welding, split, the covers design have good structural integrity, less stress concentration, high strength, high stiffness, long life and good sealing.
