    Keywords : viscous-inviscid interaction model; laminar flow wing; aerodynamics; aeroelasticity; aircraft design; Flyg- och rymdteknik; Aerospace Engineering;

    Abstract : The work presented in this thesis was performed with the aim of developing improved prediction methods for aerodynamic and aeroelastic analysis to be used in aircraft design. The first part of the thesis concerns the development of a viscous-inviscid interaction model for steady aerodynamic predictions. READ MORE

  5. 8. Numerical Methods for Turbomachinery Aeromechanical Predictions

    Author : Maria Angelica Mayorca; Damian Vogt; Torsten Fransson; Robert Kielb; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeromechanics; numerical tools; methods; turbomachinery; aeroelasticity; gas turbines; vibrations;

    Abstract : In both aviation and power generation, gas turbines are used as key components. An important driver of technological advance in gas turbines is the race towards environmentally friendly machines, decreasing the fuel burn, community noise and NOx emissions. READ MORE

  6. 9. Experimental Investigation of the Influence of Local Flow Features on the Aerodynamic Damping of an Oscillating Blade Row

    Author : Antonio Sanz Luengo; Torsten Fransson; Damian Vogt; Guillermo Paniagua; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbomachinery; Aeroelasticity; Flutter; Experimental Aerodynamics; CFD; Local Flow Features; Influence Coefficient; Linearity Assumption; Aerospace Engineering; Flyg- och rymdteknik;

    Abstract : The general trend of efficiency increase, weight and noise reduction has derived in the design of more slender, loaded, and 3D shaped blades. This has a significant impact on the stability of fan, and low pressure turbine blades, which are more prone to aeroelastic phenomena such as flutter. READ MORE
