  1. 1. Probabilistic Added Wave Resistance Predictions for Design of RoPax Ferries

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Jonathan Viinikka; [2023]
    Nyckelord :Added wave resistance in head waves; Roll-on Roll-off Passenger ferry; Probabilistic wave environment; Semi-empirical method; Adderat vågmotstånd i motsjö; Roll-on Roll-off Passagerar Fartyg; Probabilistiska vågförhållanden; Semiempiriska beräkningsmethoder;

    Sammanfattning : This thesis investigates reasons for significant uncertainties in added wave resistance predictionsand how wave conditions can potentially affect the design of RoPax ferries. The objectiveis to find a suitable prediction method of added wave resistance for the RoPax ferry designapplication. LÄS MER

  3. 2. Design and Implementation of a Rocket Launcher Hybrid Navigation

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Omar Ugolini; [2023]
    Nyckelord :launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

    Sammanfattning : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.

  7. 5. Design and Analysis of Non-symmetric Satellite Constellations

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Jomuel Danilo Costales; [2023]
    Nyckelord :Space; Satellite; Constellation; Coverage; Non-symmetric; Walker; Set Cover problem; Greedy algorithm; Space; Satellit; Constellation; Täckning; Icke-symmetrisk; Walker; Set Cover problem; Greedy algoritm;

    Sammanfattning : Satellite constellation design has been a well-studied problem since the beginning of the space age. In recent years new concepts and approaches tried to solve it with fewer satellites whilst guaranteeing coverage to the areas of interest, whether globally or regionally. LÄS MER
