  1. 1. Forced response numerical investigation of a transonic compressor rotor

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mariana Pires Gonçalves Toco Dias; [2023]
    Nyckelord :Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Sammanfattning : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. LÄS MER

  3. 2. 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

  5. 4. Aeroelastic flutter analysis with varying level of accuracy

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Nils Voigt Dahl; [2020]
    Nyckelord :flutter; aeroelasticity; aeroelastic; aerodynamics; Technology and Engineering;

    Sammanfattning : Flutter prediction is a vital part of aircraft development which requires efficient and accurate analysis methods. Saab AB Aeronautics is currently using linear analysis based on the panel method and nonlinear analysis using their in-house CFD software program. These methods are in contrast to one another in terms of computing time and accuracy. LÄS MER

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

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Aaron Dettmann; [2019]
    Nyckelord :Aeroelasticity; Simulation; CFD; FEM; VLM; Euler-Bernoulli beam theory III; Aeroelasticitet; Simulation; CFD; FEM; VLM; Euler-Bernoulli-balkmodell;

    Sammanfattning : A computational framework for linear static aeroelastic analyses is presented. The overall aeroelasticity model is applicable to conceptual aircraft design studies and other low-fidelity aero-structural analyses. A partitioned approach is used, i. e. LÄS MER
