  1. 1. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Simon Garpenquist; [2023]
    Nyckelord :Wind Tunnel Experiment; Computational Fluid Dynamics; Aerodynamic Forces; Drag Reduction; Shape Optimization; Flow around Cylinders; Yacht Racing;

    Sammanfattning : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. LÄS MER

  3. 2. Förbättring av nedgångslucka på en segelbåt

    M1-uppsats, KTH/Tillämpad maskinteknik (KTH Södertälje)

    Författare :Philip Hagberg; Jesper Henriksson; [2018]
    Nyckelord :Cost price calculation; constant force spring; generic development; life cycle; mounting schedule; sail yacht; product development; Självkostnadskalkyl; konstantkraftsfjädrar; generisk utvecklingsprocess; livslängd; monteringsschema; segelbåtar; produktutveckling;

    Sammanfattning : Linjett Segelbåtar konstruerar och producerar högkvalitativa  segelbåtar på Rosättravarvet. Detta arbete syftar till att presentera en bättre mekanisk lösning till den nedgångslucka som Linjett har idag. LÄS MER

  4. 3. Aerodynamics of Sailing Yachts : Force, Pressure and sail shape measurements as bridge between experiments and numerical simulations

    Master-uppsats, KTH/Marina system

    Författare :Francesco Giacobone; [2017]
    Nyckelord :;

    Sammanfattning : The present work reports the first systematic results obtained in wind tunnel and at full scale with theexperimental apparatus developed within the joint project among Politecnico di Milano, North Sails andCSEM. The steady state upwind aerodynamics of sailing yachts are investigated through the contemporarymeasurement of global forces, distributed pressures and sail flying shapes, and with numerical simulationsbased on Potential Theory and Navier-Stokes equations.

  5. 4. An Aeroelastic Implementation for YachtSails and Rigs

    Master-uppsats, KTH/Marina system

    Författare :Aron Helmstad; Tomas Larsson; [2013]
    Nyckelord :;

    Sammanfattning : An aeroelastic model has been developed to determine the elastic response of sailing yachts’ rigs and sails due to the aerodynamic pressure induced on the sails by the wind. A vortex-lattice method (VLM) is used to determine the aerodynamic pressure. The structural response is calculated with a non-linear finite element method (FEM). LÄS MER

  7. 5. Predicting the Effects of Interaction between Yachts Sailing Upwind

    Master-uppsats, KTH/Marina system

    Författare :Olof Detlefsen; [2012]
    Nyckelord :;

    Sammanfattning : The ever-growing yachting industry has come to play an important role in the maritime sector, resulting in an increasing demand for highly technologically advanced cruising and racing sailing yachts. In the aim of producing faster yachts and faster sails designers and sailors has come a long way understanding the science of sailing. LÄS MER
