  1. 1. Investigation and implementation of rapid prototyping in development of a high-speed light craft

    Master-uppsats, KTH/Marina system

    Författare :Ulrik Sköldkvist; [2021]
    Nyckelord :;

    Sammanfattning : Designing and constructing boats or ships is a slow, iterative process where the design goes through several steps in each iteration, and every loop in the process leads closer to the result. However, to verify if the boat's design functions, it must be built if there is no possibility to design, build, and evaluate smaller prototypes during the development. LÄS MER

  3. 2. Model Design for Further Spray Deflector investigation

    Master-uppsats, KTH/Marina system

    Författare :Xinguo Wang; [2021]
    Nyckelord :High-Speed Craft; Model Design; Spray Deflector; Höghastighetshantverk; modelldesign; spraydeflektor;

    Sammanfattning : Planing hull is one solution to break the speed barrier of conventional hull, but as the boat reaches a high speed, massive whisker spray will be developed and attached to the hull, which causes a notable resistance increase. A Swedish company Peterstep invented an innovative spray deflector that can deflect the spray backwards and harvest kinetic energy from the spray. LÄS MER

  4. 3. Experimental Validation of Innovative High-Speed Craft Spray Deflectors

    Master-uppsats, KTH/Marina system

    Författare :Fran Osmak; [2020]
    Nyckelord :;

    Sammanfattning : Hydrodynamic analysis of high-speed craft is a complex problem. For years naval architects have tried improving the eÿciency of the hull, changing its form, the number of hulls, adding spray rails or steps. LÄS MER

  5. 4. Semi-active suspension seats in High speed crafts

    Master-uppsats, KTH/Marina system

    Författare :Victor Ekström; [2019]
    Nyckelord :;

    Sammanfattning : The working environment of a high-speed-craft (HSC) can be uncomfortable and hazardous for the crew and passengers on board. This due to the repeated exposure to high levels of vibration and shocks, that can lead to reduced performance and severe injuries to the back and neck. LÄS MER

  7. 5. Active Suspension Seat for High Speed Craft

    Master-uppsats, KTH/Marina system

    Författare :Khaled Ereq; [2018]
    Nyckelord :;

    Sammanfattning : Master of Science thesis in Naval Architecture presents a study and the performance of an active seat suspension with the purpose to suppress shocks, caused by slamming in High Speed Crafts (HSCs). The system is modelled and simulated with the aid of the Mathworks software Simulink, with the main objective to evaluate if the active suspension seat has the potential to mitigate slamming impact loads to a larger extent compared to a passive suspension seat.
