  1. 31. Development and Use of System Modeler 6DOF Flight Mechanics Model in Aircraft Conceptual Design

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Niko Erä-Esko; [2022]
    Nyckelord :Aircraft Conceptual Design; Flight Mechanics; Modelling and Simulation;

    Sammanfattning : 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.

  3. 32. Framtidens hybrida stridsfordon

    Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

    Författare :Jacob Sundell; [2022]
    Nyckelord :Stridsfordon 90; Hybrid; Seriehybrid; Framtidens fordon; Combat Vehicle 90; CV90; hybrid; Electric Hybrid Vehicle; future vehicle;

    Sammanfattning : Stridsfordon 90 tillsammans med Stridsvagn 122 är i dagsläget stommen i Försvarsmaktens mekaniserade bataljoner. I Försvarsbeslutet 2020 beslutades det att Stridsfordon 90 skall successivt ersättas med ett nytt stridsfordon efter 2030. LÄS MER

  4. 33. Dynamic simulation of transforming the transport system - Based on Lotka-Volterra population modelling

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Sara Saltvedt; [2022]
    Nyckelord :Electric Vehicles; Lotka-Volterra model; System Dynamics; Sustainable Vehicles; Sustainable transport system; Elfordon; Lotka-Volterra model; System Dynamics; Hållbara fordon; Hållbara transport system;

    Sammanfattning : The transport sector plays a critical role in meeting the targets of achieving net-zero emissions. In comparison to traditional fuel vehicles (ICEVs), new energy vehicles, such as electric vehicles (EVs), have advantages of energy-saving and emission reduction. LÄS MER

  5. 34. Controlling a sliding contact on an electric vehicle with computer vision and AI

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Axel Sondh; Björn Johnsson; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Emission from road vehicles is a massive problem and contributes to climate change on our planet. One solution that people are turning to is electrical propulsion instead of fossil fuel. There are, however, problems with putting big batteries on road vehicles. LÄS MER

  7. 35. Development Model of a Gas Pressure Regulator for Spacecraft Propulsion : Design Enhancement and Testing

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FILIPPO POZZI; MARCUS SJÖBERG; [2021]
    Nyckelord :;

    Sammanfattning : This thesis treats the testing, analysis, and continued development of a mechanical pressure regulator prototype, intended for use in spacecraft propulsion systems. Herein referred to as the Adapted Mechanical Pressure Regulator (APR), the regulator is an adaptation made by the Swedish space system developer OHB Sweden AB (OSE) of an existing patented design originally intended for use outside of the space industry.
