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

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

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

   Abstract : 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. READ MORE

   Abstract : 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. READ MORE

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

   University essay from KTH/Lättkonstruktioner

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

   Abstract : 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. READ MORE

5. 4. Aeroelastic Analysis of a Morphing Wing for Airborne Wind Energy Applications

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Johannes Hall; [2017]
   Keywords : airborne wind energy; fluid structure interaction; gust wind modelling; Technology and Engineering;

   Abstract : The aim of this thesis is to set up a high-fidelity fluid structure interaction (FSI) simulation environment to study the gust load alleviation capability of camber-morphing airborne wind energy (AWE) wings. The simulation environment will enable studying the transient flow phenomena around the wing when encountering wind gusts and gives the possibility of investigating dynamic instabilities. READ MORE

6. 5. Aeroelastic forced response of a bladed drum from a low pressure compressor

   University essay from KTH/Kraft- och värmeteknologi

   Author : Julien Lamouroux; [2016]
   Keywords : Aeroelasticity; Forced response; Bladed drum; Low pressure compressor;

   Abstract : The purpose of this master thesis is to provide a reliable methodology to predict the forced response of a monoblock bladed drum from a low pressure compressor. Pre-test forced response calculations have already been made at Techspace Aero in 2013. READ MORE
