  1. 1. Investigation of the wing design and endurance of an ultralight electrical aircraft

    Master-uppsats, Lunds universitet/Innovation

    Författare :Vanda Ericson; Jonathan Palmgren; [2022]
    Nyckelord :Aerodynamics; Electrical Aviation; CFD; Endurance; Drag; Technology and Engineering;

    Sammanfattning : The goal of this thesis was to explore the conversion of a propeller driven two-seater combustion airplane to an electrical airplane. Four different wing designs were considered. Two variations of Blackwing Sweden AB’s current Blackwing wing (BW), a longer wing (BW-L) and a shorter wing (BW-S), as well as a new wing with a different airfoil (GW). LÄS MER

  3. 2. Analysis and Initial Optimization of The Propeller Design for Small, Hybrid-Electric Propeller Aircraft

    Master-uppsats, KTH/Flygdynamik

    Författare :Ali Alshahrani; [2020]
    Nyckelord :Electric; hybrid; Propeller; Optimization; variable pitch; fixed pitch; blades number; Eldrivet; hybrid; Propeller; Optimering; justerbar vinkel; fast vinkel; bladnummer;

    Sammanfattning : This thesis focuses on the optimization of the electric aircraft propeller in order to increaseflight performance. Electric aircraft have limited energy, particularly the electricmotor torque compared to the fuel engine torque. For that, redesign of the propeller forelectric aircraft is important in order to improve the propeller efficiency. LÄS MER

  4. 3. Autonomous Hover Control System for a Radio-Controlled Aerobatic Airplane

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Erik Olov Ljudén; [2018]
    Nyckelord :mechatronics; hovering; airplane; PWM; aerobatics; mekatronik; hovring; flygplan; PWM; konstflygning;

    Sammanfattning : Being able to fly has always been one of humanities greatestdreams, and today anyone can purchase a Radio-Controlled(RC) airplane or helicopter and learn how to fly. ExperiencedRC pilots perform stunts such as “prop hanging”.This is when an airplane flies vertically while maintainingits position with the propeller being the only motive force. LÄS MER

  7. 5. Flygteknik : Konceptstudie av ett obemannat flygplan

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

    Författare :Simon Callbo; Samuel Gottfarb-Bart; [2014]
    Nyckelord :;

    Sammanfattning : Unmanned aerial vehicles (UAV’s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV’s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries. LÄS MER
