  1. 16. Comparison of Aerodynamic Methods for the Computation of Control Surface Loads

    Master-uppsats, KTH/Flygdynamik

    Författare :Sara Kirchmayr; [2015]
    Nyckelord :;

    Sammanfattning : This paper presents loads computations for the generic UCAV configuration F19, originally devised by the German Aerospace Center (DLR). Different aerodynamic methods are investigated and their effect on concentrated structural loads is assessed. Design manoeuvres are defined based on the manoeuvre authority. LÄS MER

  3. 17. Aeroelastic Simulation of small wind turbine using HAWC2

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Sudheesh Sureshkumar; [2014]
    Nyckelord :HAWT; Aeroelastic modelling; Multibody dynamics; HAWC2; BECAS;

    Sammanfattning : Horizontal axis wind turbines are subjected to various static and dynamic loads under different load situations. Aeroelastic modelling is used in wind turbines to couple the aerodynamic and structural loads acting on the turbine and to analyse the aeroelastic response. The small wind turbine Nimbus 1. LÄS MER

  4. 18. Study of the Fan Forced Response due to Crosswind

    Master-uppsats, KTH/Aerodynamik

    Författare :Victor Guillard; [2014]
    Nyckelord :;

    Sammanfattning : Structures of an aircraft engine are not completely rigid. Therefore when they are subjected to aerodynamic loading, those structures will deform elastically and their shape will change, especially fan blades because of their size. LÄS MER

  5. 19. Study of Various Methods for Modeling Gust Penetration

    Master-uppsats, KTH/Aerodynamik

    Författare :Ludovic Colo; [2014]
    Nyckelord :;

    Sammanfattning : Gust load computations are one of the various load cases computations required by the regulation in order to get an aircraft certified. These loads can even be the ones which have to be used for the structural sizing of the vertical and horizontal tail or the main wing of the aircraft. LÄS MER

  7. 20. Wind Loads on Bridges : Analysis of a three span bridge based on theoretical methods and Eurocode 1

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :M. Sajad Mohammadi; Rishiraj Mukherjee; [2013]
    Nyckelord :Wind load; dynamic response of a continuous bridge; theoretical methods; Eurocode 1; vortex shedding; aerodynamic and aeroelastic instabilities; Natural frequencies.;

    Sammanfattning : The limitations lying behind the applications of EN-1991-1-4, Eurocode1, actions on structures-general actions-wind load-part 1-4, lead the structural designers to a great confusion. This may be due to the fact that EC1 only provides the guidance for bridges whose fundamental modes of vibration have a constant sign (e.g. LÄS MER
