  1. 1. Electrically powered manoeuvring of water jets

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Joel Engström; [2021]
    Nyckelord :Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

    Sammanfattning : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.

  3. 2. Design and system integration of a rim jet solution utilizing DFMA

    Master-uppsats, KTH/Integrerad produktutveckling

    Författare :Gustav Adolf Adler; [2020]
    Nyckelord :;

    Sammanfattning : Moving a new innovative idea from the drawing board to production is no easy feat. The Swedish sea rescue society (SSRS) has for the past years fostered a new design solution for their jet skis, a alternative water jet that removes the centre hub and utilises rim drive technology.

  4. 3. Användarcentrerad utvärdering samt utveckling av ett larmsystem för vattenjet-propulsor

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :Astrid Heed; [2019]
    Nyckelord :Larm; Larmssystem; Visuell presentation; Situationsmedvetenhet; Naturligt Beslutsfattande;

    Sammanfattning : The purpose of this master thesis is to investigate how alarm systems and their visualizations, as well as signals affect work situations and decision making processes aboard vessels with water jet propulsion. Furthermore, this study aims to identify important aspects of the perception of alarm systems and which aspects that are more or less affected by stress, lack of information as well as audible and visual signals.

  5. 4. Analysis of the intake grill for marine jet propulsion

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

    Författare :Marcus Söderberg Jansson; [2019]
    Nyckelord :Intake grill; Waterjet; Fluid Dynamics; Intagsgaller; Vattenjet; Strömning;

    Sammanfattning : Marine waterjet propulsion is a technology that has been developed and refined since the early 1950’ and is proven highly useful for high speed applications with vessels in varying sizes. The intake grill is a component that is mounted in line with the hull to prevent debris from traveling through the waterjet. LÄS MER

  7. 5. Rim-Jet - A Mechanical Design for a Shaft-less Propulsor

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Pablo Sanchez Santiago; [2019]
    Nyckelord :Conceptual design; debris; propulsor; rescue operations; verify; Driftsäkerhet; framdrivning; propulsor; räddningsbåt; Sjöräddning;

    Sammanfattning : During sea rescue operations it is common for the rescue vessels to operate in water with high number of debris that can get stuck in the propulsor. In particular plastic ropes that can get tangled around the shaft and melt causing a complete stop or damage the motor. LÄS MER
