1. Tools and Challenges in Evaluating Control Surface Airworthiness for a Blended-Wing-Body UAV
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : 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
2. Electrical Propulsion System Design of a Blended Wing Body UAV
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)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.

4. Green Raven Structural Design : Optimization of Internal Structure for Blended Wing Bodies
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)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
5. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure
Master-uppsats, KTH/LättkonstruktionerSammanfattning : 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
