    Author : Oskar Moström; [2023]
    Keywords : tribology; hydrogen embrittlement; mechanical engineering; rolling element bearing; machine elements; design; mechanical design; CAD; mechanical construction; construction; material science; Tribologie; Wasserstoffversprödung; Maschinenbau; Wälzlager; Maschinenelemente; Design; Maschinenkonstruktion; CAD; mechanischer Bau; Konstruktion; Materialwissenschaft; tribologi; väteförsprödning; maskinteknik; rullningselementlager; maskinelement; design; mekanisk design; CAD; mekanisk konstruktion; konstruktion; materialvetenskap; lager;

    Abstract : This Master's thesis is part of the Hydrogen Embrittlement in Rolling element bearings project (HERo) initiated at Luleå University of Technology (LTU), with the primary objective of determining critical hydrogen concentrations in bearing steel for rolling element bearings. The specific aim of this Master's thesis is to design a test rig that enables the investigation of the effects of hydrogen embrittlement on rolling element bearings under load. READ MORE

  3. 7. Airspeed estimation of aircraft using two different models and nonlinear observers

    University essay from Linköpings universitet/Fordonssystem

    Author : Alexander Roser; Anton Thunberg; [2023]
    Keywords : sensor fusion; flight mechanics; Kalman filter; extended Kalman filter; unscented Kalman filter; pitot tube; airspeed estimation; simulation;

    Abstract : When operating an aircraft, inaccurate measurements can have devastating consequences. For example, when measuring airspeed using a pitot tube, icing effects and other faults can result in erroneous measurements. READ MORE

  4. 8. Concept investigation into Metal Plasma Source for High Powered Space Applications

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Ludvig Borg; [2023]
    Keywords : High-powered; Electric Propulsion; Vacuum Arc Thruster; VASIMR; Metal Plasma; Magnetohydrodynamics; COMSOL Multiphysics;

  5. 9. Underwater Thrust Vectoring

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

    Author : Victor Schröder; [2023]
    Keywords : ;

    Abstract : Denna uppsats kommer att titta på designen för ett undervattensrörelse och kontrollsystem för en mindre forskningsubåt som kallas SAM. Denna ubåt delar många liknelser med andra autonoma undervattensfordon mer specifikt dennes tub liknande design. Där SAM skiljer sig från normen är hur den styr under vattnet. READ MORE

  6. 10. Investigation of a Novel Atmosphere-Breathing Electric Propulsion Platform and Intake

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

    Author : Kun Feng; [2023]
    Keywords : ABEP; VLEO; DSMC; FMF; Orbital Aerodynamics; ABEP; DSMC; VLEO; FMF; Orbital Aerodynamics;

    Abstract : Very Low Earth Orbit (VLEO) provides many benefits for space missions, including better image resolution for Earth observation, better telecommunication link with ground stations, lower launch cost, lower risk of collisions, and fast end-of-life disposal. The last point in benefit is also the main challenge for placing satellites in VLEO. READ MORE
