5. Analysis of Barreling and Tolerance Effects of Blade Attachments
University essay from KTH/Hållfasthetslära (Avd.)Abstract : In a gas turbine rotor, the Blade-Disc attachment is often a critical part. This part needs to endure both high contact stress and high temperature. Thus, the prediction of the life of the attachment becomes important. Furthermore, the refinement of the Blade-Disc attachment is worth to study, to extend the lifetime of the turbine rotor. READ MORE
