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

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Sara Ghika; [2021]
    Nyckelord :Aerospace; wind tunnel testing; lightweight structures; UAV; Mekanisk Design; Analys och Tillverkning av Vindtunnelmodell och Stödstruktur;

    Sammanfattning : This volume covers the phases from design to manufacturing of a wind tunnel test support structure for a conceptual blended wing-body UAV designed by KTH Green Raven Project students. The innovative aircraft design demonstrates sustainability within aviation by utilizing a hybrid electric-fuel cell propulsion system. LÄS MER

  3. 12. Propulsion system for a small unmanned aerial vehicle

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Dennis Wilkman; Oscar Andersson; [2020]
    Nyckelord :;

    Sammanfattning : For unmanned aerial vehicles there is a wide variety of selection for propulsion systems. Depending on the specific choice of system, the characteristics of the aircraft vary significantly. The choice is also dependent on the size of the UAV itself as well as desired performance and utility. LÄS MER

  4. 13. Unmanned Aerial Vehicle Powered by Hybrid Propulsion System

    Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Elsa Åkesson; Maximilian Kempe; Oskar Nordlander; Rosa Sandén; [2020]
    Nyckelord :UAV; PEMFC; Energy Management Strategy; Simulink; Fuel Cell; Hybrid Propulsion System;

    Sammanfattning : I samband med den globala uppvärmningen ökar efterfrågan för rena och förnybara bränslen alltmer i dagens samhälle. Eftersom flygindustrin idag är ansvarig för samma mängd växthusgaser som all motortrafik i Sverige, skulle ett byte till en avgasfri energikälla för flygfarkoster vara ett stort framsteg. LÄS MER

  5. 14. Feasibility Study of the Decarbonisation and Electrification of a Commuter Ferry in Stockholm city

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Matilda Helgesson; [2020]
