  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

  3. 2. 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.

    Sammanfattning : With increasing focus on climate change more research for net-zero emission are being made in the aviation industry.This project focuses on electric propulsion on a unmanned aerial vehicle (UAV) with a blended wing body (BWB) design. LÄS MER

  5. 4. Green Raven Structural Design : Optimization of Internal Structure for Blended Wing Bodies

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

    Författare :Oscar Ehrler; Anton Holmén; [2022]
    Nyckelord :UAV; Blended wing body; BWB; wing structure; Scots pine; Fiber reinforced plastic; FRP; Off axis loading of fiber reinforced plastic; wing mount;

    Sammanfattning : The student inclusive Green Raven project of the KTH-Aero faculty requireda small blended wing model of their new flying wing design. The small scalemodel will be used for various flight tests. The goal of this specific project was tocreate an internal structure for the small scale model, including an outer shell. LÄS MER

  7. 5. Aerodynamic Analysis of a Blended Wing Body UAV

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

    Författare :Oliver Harrisson; [2022]
    Nyckelord :Computational Fluid Dynamics CFD ; Blended Wing Body BWB ; ANSYS Fluent; Aeronautics; Unmanned Aerial Vehicle UAV ;

    Sammanfattning : The focus of this thesis is to analyse the flight characteristics of the blended wingbody (BWB) unmanned aerial vehicle (UAV) Green Raven currently being developed by students at the Royal Institute of Technology (KTH) in Stockholm,Sweden. The purpose of evaluating a BWB aircraft is due to its potential increasein fuel efficiency and payload compared to conventional aircrafts which would enable more sustainable flights. LÄS MER
