1. 21. Fluttering Analysis in Wind Turbine Blade

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Prabaharan Elangovan; [2012]
   Nyckelord :Wind turbine blade; Aerodynamic loads; Finite Element Method; Mode shapes; Deformations and ANSYS.;

   Sammanfattning : The wind turbine blades often subjected by a phenomenon fluttering which leads to a structural damage. Therefore, it is necessary for design engineers to predict the fluttering behavior while designing the blades. LÄS MER

3. 22. Aerodynamic Propeller Model for Load Analysis

   Master-uppsats, KTH/Matematik (Inst.)

   Författare :Mario Heene; [2012]
   Nyckelord :;

   Sammanfattning : An aerodynamic propeller model, which can contribute to the prediction of structural loads experienced by aircraft in different flight maneuvers is presented.The model is based on Blade Element Momentum theory and is able to predict the unsymmetrical and frequency-dependent forces and moments induced by the propeller on the airplane structure at steady and unsteady inflow-conditions.

4. 23. Investigation Of Different Airfoils on Outer Sections of Large Rotor Blades

   Kandidat-uppsats, Akademin för innovation, design och teknik

   Författare :Sebastian Thuné; Torstein Soland; [2012]
   Nyckelord :wind; turbine; Rotor; Blade; HAWT;

   Sammanfattning : Wind power counts for roughly 3 % of the global electricity production. In the chase to produce greener power, much attention lies on getting more electricity from the wind, extraction of kinetic energy, with help of wind turbines. LÄS MER

5. 24. Automatic Fusion of Fidelity sources ofAerodynamic Data : Simulating Aircraft Stability And Control Characteristics for Use in Conceptual Design

   Master-uppsats, KTH/Aeroakustik

   Författare :Sofia Chevrolat; [2011]
   Nyckelord :;

   Sammanfattning : CFD use has increased signi cantly in airplane conception, and the industry demands more andmore precise and reliable tools. This was the goal of the SimSAC project. The result is CEASIOM,a computerized environment made of several modules for the design and prediction of the aircraft'scharacteristics. LÄS MER

7. 25. Aeroelastic tailoring of a sailplane wing

   Master-uppsats, KTH/Flygdynamik

   Författare :Björn Persson; [2011]
   Nyckelord :;

   Sammanfattning : In this paper a process for how to perform aeroelastic tailoring of a sailplane wing is described. The analysis was carried out with the aid of a Finite Element solver and the aerodynamic loads were calculated with a potential flow solver. LÄS MER
