  1. 1. Conceptual design of the next generation gas turbines : Modelling of a hybrid electric mixed turbofan for a trainer aircraft

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

    Author : Sophia Fisher; Michael Åkerström; [2023]
    Keywords : Hybrid propulsion; mixed turbofan; parallel configuration; performance;

    Abstract : To mitigate climate change, all sectors must contribute their part. Electric propulsion system is a promising approach to reduce emissions from the aviation industry. A major challenge is however the low energy density in today’s battery technology. READ MORE

  3. 2. Turbofan Engine Modeling - For The Fighter Aircraft of The Future

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Aria Tahmasebi; [2022]
    Keywords : Turbofan; Engine; Turbofan engine; Gas turbine; Engine model; Engine modeling; Simulink; Simulink engine; Fighter aircraft; SAAB; Engine performance; Engine optimization;

    Abstract : The demand for turbofan engine performance development is high in the military industry. However, to develop the engine, it is necessary to predict its performance, and engine testing is both time-consuming and costly. Therefore, simulation is an effective approach to predicting the engine’s performance. READ MORE

  4. 3. Numerical evaluation of the ground vortex

    University essay from KTH/Teknisk mekanik

    Author : Martin Babo; [2022]
    Keywords : Turbofan engine; CFD; Flow simulation; Ground Vortex; External aerodynamics;

    Abstract : This master thesis covers the realization of a CFD calibration study regarding the numerical simulation of the ground vortex phenomenon. As part of InVIGO project (EU CleanSky2), wind tunnel test campaigns were performed using a nacelle model combined with a movable raised floor. READ MORE

  5. 4. Machinery Health Indicator Construction using Multi-objective Genetic Algorithm Optimization of a Feed-forward Neural Network based on Distance

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jacob Nyman; [2021]
    Keywords : Prognostics; Health Indicator Construction; Remaining Useful Life Prediction; Multi-objective Optimization; Distance; Prognostik; Hälsoindikatorkonstruktion; Återstående Livslängd; Multiobjektiv Optimering; Avstånd;

    Abstract : Assessment of machine health and prediction of future failures are critical for maintenance decisions. Many of the existing methods use unsupervised techniques to construct health indicators by measuring the disparity between the current state and either the healthy or the faulty states of the system.

  6. 5. 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
