3. Model Adaptation of a Mixed Flow Turbofan Engine
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : Gas turbine performance models are usually created in an object oriented manner, where different standard components are connected to form the complete model. The characteristics of these components are often represented by component maps and empirical correlations. READ MORE

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
