  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. Flight Mechanics of an Airship

    Master-uppsats, KTH/Flygdynamik

    Författare :Pierre Miguel Merlet; [2020]
    Nyckelord :;

    Sammanfattning : Airships were very popular 90 years ago with, for example, german Zeppelins. Now theyare back for several reasons, like their low energy consumption.But there are also still many problems to deal with like their sensitivity to wind gusts.In addition, the airships need more studies to improve their flight mechanics and sensitivityto the wind.

    Sammanfattning : Detta projekt undersöker möjligheterna att bedöma   discar avsedda för discgolf efter en skala grundad i vetenskapliga tester.   Tester görs i vindtunneln hos Sportstech Research Centre vid   Mittuniversitetet i Östersund i samarbete med Kastaplast AB. LÄS MER

  5. 4. L₁adaptive control of a generic fighter aircraft

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Andreas Myleus; [2013]
    Nyckelord :;

    Sammanfattning : This master's thesis was performed at the section of Flight Control Systems at SAAB Aeronautics in Linköping as a part of my Master of Science in Aerospace Engineering at KTH, Stockholm. This report examines the use of L₁ adaptive control to stabilize the inner longitudinal and lateral loops of a generic fighter aircraft, in the event of failure of the system that measures current speed and altitude.

  7. 5. Positioning and Trajectory Control of an Autonomous Helicopter using Real Time Kinematic GPS

    Master-uppsats, Reglerteknik; Tekniska högskolan

    Författare :Josef Högberg; Staffan Sjöqvist; [2013]
    Nyckelord :Real Time Kinematic GPS; quadrocopter; motion path; cubic splines; automatic control;

    Sammanfattning : During this master’s thesis project a control system for a quadrocopter has been developed. A quadrocopter is a small helicopter with four rotors which is controlled by a hand held controller by an operator positioned on the ground. This master thesis report treats three different main subjects. LÄS MER
