  1. 1. Attitude and orbit control analysis of a solar sail spacecraft for Space sunshade missions in the vicinity of the sub-Lagrange 1 point

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

    Författare :Benjamin Jouanneau; [2022]
    Nyckelord :;

    Sammanfattning : This Master thesis report contains a complete attitude and orbit control analysis for solar sail spacecraft in the Circular-Restricted-3-Body-Reference frame. The overall goal of the project is to drive one solar sail from the edge of the Earth Sphere of Influence to a vicinity of the sub-Lagrange1 point. LÄS MER

  2. 2. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Luis Alfonso Penela Guerrero; [2022]
    Nyckelord :Aerospace; wind tunnel testing; lightweight structures; UAV; composite materials; Flyg; vindtunneltestning; Lättkonstruktioner; UAV; kompositmaterial;

    Sammanfattning : The use of wind tunnel models for aerodynamic research is nowadays indispensable to aviation progress in the last years as aircrafts have become more complex. Wind tunnel model design and manufacturing has adopted many different processes and materials such as the use of a five-axis CNC; making this process a relatively long and expensive one. LÄS MER

  3. 3. Towards sustainable shipping: Recommendations for the telescopic mast design of a sailing cargo vessel

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Lukas Blau; [2021]
    Nyckelord :Oceanbird; telescopic mast; conceptual design; sailing cargo vessel;

    Sammanfattning : A comparative study is carried out to investigate the most promising route towardsthe lightweight construction of a retractable mast for a sailing cargo vessel.Four design families are developed and compared. The primary criteria forjudgment are the structural mass, strength, and stiffness in relation to a providedbenchmark design. LÄS MER

  4. 4. Finite Element Analysis of Stresses in the MIST CubeSat due to Dynamic Loads During Launch

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Carl Järmyr Eriksson; [2021]
    Nyckelord :Satellite; CubeSat; Nanosatellite; Dynamic Loads; Launch Loads; Finite Element Analysis; FEA; Quasi-static Acceleration; Modal Analysis; Random Vibration; Shock Loads; satellit; CubeSat; nanosatellit; dynamiska laster; uppskjutningslaster; finita elementmetoden; FEM; kvasistatisk acceleration; modalanalys; stokastiska vibrationer; chocklaster;

    Sammanfattning : A finite element model of the CubeSat MIST was created, in order to assess the stresses that occur in the satellite in response to loads during its launch. Due to size limits of thesoftware used, simplifications had to be made to the geometry of the model. LÄS MER

  5. 5. Enhancing the endurance of UAVs by the use of structural power composites: System-level study of a flying wing

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Gustav Burman; [2021]
    Nyckelord :;

    Sammanfattning : This thesis studies the feasibility of integrating the novelStructural Battery (SB)[1] into the airframe of a UnmannedAerial Vehicle (UAV). The potential advantages in terms ofmass, range and endurance are studied.The aircraft performance is analysed using conventionalflight mechanics, modelled in Matlab and Xfoil. LÄS MER
