1. 1. CFD validation of a new gas turbinestage design with experimental data

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Claudia Florentina Balan; [2022]
   Keywords : ;

   Abstract : Gas turbines are present in two energy-intensive sectors: aviation and energy production. Improving the efficiency of gas turbines has a huge impact on the reduction of CO2 in the atmosphere, therefore many research groups are studying innovative strategies to improve the performance of these turbines.

4. 3. Model Adaptation of a Mixed Flow Turbofan Engine

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Oskar Lindkvist; [2020]
   Keywords : Turbofan engine; Gas turbine; Performance model; Component maps;

   Abstract : 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. 4. Performance Assessment of Electrical Motor for Electric Aircraft Propulsion Applications : Evaluation of the Permanent Magnet Motor and its Limitations in Aircraft Propulsion

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Mathias Beckman; Alex Christy Gerald Volden; [2019]
   Keywords : Electric Aircraft; Permanent Magnet Electrical Motor; Losses; Hybrid-Electric Propulsion System; Environment; Global Warming; Aircraft Emission;

   Abstract : This thesis project will evaluate which kind of electrical motor is best suited for aircraft propulsion and which parameters effect the efficiency. An economic analysis was conducted, comparing the fuel price (Jet A1) for a gas turbine and the electricity price for an electric motor of 1MW. READ MORE

6. 5. Analysis of Barreling and Tolerance Effects of Blade Attachments

   University essay from KTH/Hållfasthetslära (Avd.)

   Author : Yuanyuan Xu; [2018]
   Keywords : ;

   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.
