  1. 1. Tools and Challenges in Evaluating Control Surface Airworthiness for a Blended-Wing-Body UAV

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

    Författare :Anton Åkesson; [2023]
    Nyckelord :;

    Sammanfattning : For transport aeroplanes the Blended-Wing-Body (BWB) configuration shows promise in improving aerodynamic efficiency. The Green Raven project strives to demonstrate hydrogen fuel-cell-electric propulsion on a 4 m wingspan BWB. LÄS MER

    Sammanfattning : There is an ever growing need for environmentally sustainable alternatives in today's society due to the looming threat of greenhouse gasses. One field where the need for new environmentally friendly solutions is needed is the aviation industry. LÄS MER

  4. 3. Aerodynamic Analysis of Reflex Airfoils at Low Reynolds Numbers

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

    Författare :Alexander Elliott Meyer Ströborg; [2022]
    Nyckelord :low Reynolds number; reflex airfoils; CFD; XFOIL;

    Sammanfattning : Low Reynolds number airfoil analysis has become increasingly significant as urban air mobility vehicles and unmanned aerial vehicles surge in popularity. The Green Raven project at KTH Aero aims to use reflex airfoils where little data is available beyond classical analysis. LÄS MER

  5. 4. Electrical Propulsion System Design of a Blended Wing Body UAV

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

    Författare :Kevin Azad; Felix Fungula; [2022]
    Nyckelord :Aerospace; Aviation; Blended Wing Body; Electrical; Green Raven; Propeller; Propulsion; UAV;

    Sammanfattning : The conventional tube-and-wing aircraft has been around since the 1950s, with little to no innovative progress being made towards redesigning the conventional aircraft. The blended wing body (BWB) shape fuses the wing of the aircraft with the fuselage increasing structural strength while also increasing potential surface area to create lift, making it more efficient than conventional wing shapes.
