  1. 16. Implementation of Machine Learning for Classification of Flight Simulation Data

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Karl Persson; William Josefsson Rudberg; [2022]
    Nyckelord :Machine learning; Classification; Flight mechanics; Flight simulations; FCAS; Gripen; Maskininlärning; Klassificering; Flygmekanik; Flygsimuleringar; FCAS; Gripen;

    Sammanfattning : The main objective of this thesis project is to explore the possibility of using machine learning as a way of categorizing flight simulation outcomes. If such a possibility exists, the process of analyzing whether a new configuration stays within given boundaries can be streamlined. LÄS MER

  3. 17. Improving Aircraft Fuel Consumption Prediction through Ensemble Learning

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Hanlin Gongzhang; [2022]
    Nyckelord :Aeronautics; Commercial Aircraft; Aircraft fuel consumption; Flight data; Aircraft performance model; Aircraft fuel consumption modelling; Weighted average ensemble; Machine learning; Flygteknik; Kommersiellt flyg; Flygplanens bränsleförbrukning; Flygdata; Flygplanens prestandamodell; Flygplans förbrukningsmodellering; Viktad medelvärdesensemble; Maskininlärning;

    Sammanfattning : Performance models provided by aircraft manufacturers are used by aircraft operators to perform flight path simulations aiming to reduce aircraft fuel consumption. However, performance models are generic and does not account for the performance deviations of each aircraft individual. LÄS MER

  4. 18. Jet fragmentation in shaped charges

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Joakim Ericson; [2022]
    Nyckelord :Shaped charges; numerical simulation; jet fragmentation; Riktad sprängverkan; numerisk simulering; strål-fragmentering;

    Sammanfattning : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. LÄS MER

  5. 19. Stacking Ensemble Classification applied to US flight delay prediction during the COVID-19 pandemic

    Magister-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Patrick Schwarz; [2022]
    Nyckelord :Stacking Ensemble; Machine Learning; Flight Delays; Classification;

    Sammanfattning : This thesis aims to show that a Stacking Ensemble of multiple base-learners can provide a more accurate prediction of commercial flight delays between the ten largest US airports than the individual prediction models. Three types of machine learning models, namely LASSO, Random Forests and Neural Networks are used as base-learners with different hyper- parameters. LÄS MER

  7. 20. Oil Autonomy of a Turbojet

    Master-uppsats, KTH/Flygdynamik

    Författare :Florian Steiner; [2022]
    Nyckelord :Fluid Mechanics; Turbojet; Oil circuit; Fluid Mekanik; Turbojet; Oljekrets;

    Sammanfattning : The oil circuit of a jet engine is required to lubricate and cool mechanical parts. The oil is pumped from the oil tank and flows through heat exchangers. Then it is injected on the bearings for lubrication and cooling, before being scavenged at the bottom of the sumps and finally flows back to the oil tank. LÄS MER
