11. Miljökonsekvenser på flygplatser som uppkommer vid trafikering med elflygplan
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Världen är i en omställning för en hållbarare framtid och det inkluderar miljövänligare transporter. Elflygplan är under utveckling och de kan fylla ett syfte för att minska flyg- trafikens miljöpåverkan. LÄS MER
12. Investigations of the Transient Luminous Events with the small satellites, balloons and ground-based instruments
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : The lightning is the natural source of electromagnetic radiation. It is an atmospheric electrical discharge. However, since recent times, it was discovered that there are other types of lightning besides those that are visible to the naked eye. They are called TLEs (Transient Luminous Event) and take place above the clouds during thunderstorms. LÄS MER
13. Investigation of the wing design and endurance of an ultralight electrical aircraft
Master-uppsats, Lunds universitet/InnovationSammanfattning : 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
14. Come Fly with Me (Sustainably) : Pathways to Sustainable General Aviation and Private Pilot Training
Magister-uppsats, Högskolan i Gävle/MiljövetenskapSammanfattning : Whereas commercial aviation is attempting to achieve the reduction of its substantial carbon footprint, general aviation’s (GA) climate change contribution is negligibly small, which is why the sector is facing other sustainability challenges mainly entailing the operation of dated technology and aircraft, increasing regulatory constraints, rising costs, noise emissions, and popular discontent, as well as remaining the last mobility sector in the world to still use leaded fuels. Throughout recent years, there have been remarkable sustainability trends in GA as well as heightened efforts to improve its emissions profile (noise, pollutants, CO2) and environmental reputation, for instance by the increased use of electric aircraft, especially for private pilot training.

15. Development and Use of System Modeler 6DOF Flight Mechanics Model in Aircraft Conceptual Design
Master-uppsats, Linköpings universitet/Fluida och mekatroniska systemSammanfattning : This thesis presents a tool for conceptual design of a traditional configuration aircraft by using a parametric six degrees of freedom (6DOF) flight mechanics model implemented in the Modelica Language using Wolfram System Modeler. Being first only able to model and simulate the uncontrolled flight of an aircraft with fixed mass and centre of gravity (CG), and requiring detailed aerodynamic parameters as an input, the 6DOF model is improved by developing new features to reduce the number of required inputs while also increasing the data output of the simulations.
