  1. 1. Simulations of a self-stabilizing fully submerged hydrofoil

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Henry Jacobson; [2023]
    Nyckelord :Hydrofoil; Self-Stabilizing; Lifting Line Theory; Fluid Mechanics; Numerical Methods; Backward Differentiation Formula; Fully Submerged Hydrofoil; Bärplan; bärplansbåt; självstabiliserande; lyftande linjeteori; strömningsme- kanik; numeriska metoder; Backward Differentiation Formula; fullt nedsänkt bärplan;

    Sammanfattning : Two models of a self-stabilizing hydrofoil system is developed where the effects from the struts and hydrofoil give torques for angular rotations. Lifting line theory for the hydrofoil which can twist is used. Nonlinear versions of the models are also developed and compared to find that the linear models use valid approximations. LÄS MER

  3. 2. Extended Kalman Filter as Observer for a Hydrofoiling Watercraft : Modelling of a new hydrofoiling concept, based on the Spherical Inverted Pendulum Model

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Adam Thålin; [2022]
    Nyckelord :Extended Kalman Filter; Hydrofoiling; Spherical Inverted Pendulum; Sensor Fusion; Simulink; Bärplan; Extended Kalman Filter; Farkostteknik; Inverterad Pendel; Sensorfusion; Sex frihetsgrader; Simulink;

    Sammanfattning : Hydrofoiling in general has the potential to revolutionize watercraft in the future since it allows smoother and faster transport on water with less energy consumption than traditional planning hulls. Even if the concept of hydrofoiling has been around since the last century, development in control theory and material science together with increased computing power has led to a growing interest for the technology.

    Nyckelord :Design; electric boat; hydrofoil; retraction mechanism;

    Sammanfattning : The Swedish Sea Rescue Society (SSRS) is a non-profit organisation which performs themajority of rescue missions on Swedish waters. SSRS together with many other companies arecurrently under development of a novel boat design which is battery powered. LÄS MER

  5. 4. Robust motion control strategies for hydrofoil-equipped naval vessels considering scaling effects.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :HENRIK STRÖMQVIST; [2019]
    Nyckelord :;

    Sammanfattning : Hydrofoil-equipped naval vessels are not new. The technique appeared at the beginning of the 20th century and there are still new developments within the field. LÄS MER

  7. 5. Optimal configuration of the mechanical structure and flap actuator for hydrofoils

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Stanislav Minko; [2019]
    Nyckelord :;

    Sammanfattning : Hydrofoil vessels are becoming more popular and driving marine development forward. Since the water friction is greatly reduced, they allow achieving higher speeds and electrification of the boats. FoilCart is a full electric active controlled hydrofoil boat designed as a research project at KTH. LÄS MER
