  1. 1. An aeroelastic prediction model for slender wings in supersonic flow

    Master-uppsats, KTH/Flygdynamik

    Författare :Zakarias Priebe; Alexander Hasp Frank; [2021]
    Nyckelord :;

    Sammanfattning : Aeroelasticity is a multidisciplinary subject encompassing several fields of study. Aeroelastic behaviour is defined by the relation between inertial-, elastic- and aerodynamic forces that appear in dynamic systems in steady- or unsteady conditions. LÄS MER

    Sammanfattning : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. LÄS MER

  4. 3. Deflection measurements with 3D close range photogrammetry

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Guillaume Defromont; [2021]
    Nyckelord :Photogrammetry; Computer Science; Optimization; Aero-elasticity; Fotogrammetry; Datvetenskap; Aeroelasticitet;

    Sammanfattning : Photogrammetry is a great technology to check and track deformations on anysurface. This information is critical in many tranportation industries such as aeronautics and the automotive industry. In this thesis report photogrammetry measurements were done using 2 Aicon cameras providing 3D targets coordinates. LÄS MER

  5. 4. Loosely coupled, modular framework for linear static aeroelastic analyses

    Master-uppsats, KTH/Lättkonstruktioner
