    Nyckelord :Stridsfordon 90; Hybrid; Seriehybrid; Framtidens fordon; Combat Vehicle 90; CV90; hybrid; Electric Hybrid Vehicle; future vehicle;

    Sammanfattning : Stridsfordon 90 tillsammans med Stridsvagn 122 är i dagsläget stommen i Försvarsmaktens mekaniserade bataljoner. I Försvarsbeslutet 2020 beslutades det att Stridsfordon 90 skall successivt ersättas med ett nytt stridsfordon efter 2030. LÄS MER

  4. 8. Parametric study on hybrid rocket propulsion system performance measured by the system specific impulse

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Adam Bussmann; [2022]
    Nyckelord :Hybrid; Hybrid propulsion; Hybrid propulsion system; System specific impulse;

    Sammanfattning : Hybrid rocket motors have become of great international interest during the last couple of years. A hybrid rocket motor is propelled by the use of a solid fuel and a liquid oxidizer. The fundamental principle of the hybrid propelled system is that the liquid oxidizer is injected into a combustion chamber to enable the combustion of the solid fuel. LÄS MER

    Sammanfattning : Improving the efficiency and performance of vehicle propulsion systems has always been desirable, and with increasing environmental awareness this has become increasingly topical. A particularly strong focus today is at fossil-free alternatives, and there is a strong trend for electrification. LÄS MER

  7. 10. 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.
