  1. 1. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Vikramjeet Das; [2023]
    Keywords : rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

    Abstract : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. READ MORE

  3. 2. Autonomous Propulsion for a GPR-UGV

    University essay from Umeå universitet/Institutionen för fysik

    Author : Fredrik Wall Eskilsson; [2022]
    Keywords : robotics; gpr; autonomous; robot; ros; slam;

    Abstract : This thesis presents the research and development behind the integration of an autonomous propulsion system for a four-wheeled Ground Penetrating Radar (GPR) measurement unit, previously requiring manual operation. In order to ease the administration of the complex new system, Robot Operating System (ROS) 2 was used as middleware, where an implementation of Light Detection And Ranging (LiDAR) 3D-SLAM (Simultaneous Localization And Mapping) served to secure precise localization of the Unmanned Ground Vehicle (UGV) and mapping of its environment.

  4. 3. Functionnal Modelling and Simulation of the Off-Design Operation of a Cryogenic Engine

    University essay from KTH/Kraft- och värmeteknologi

    Author : Brice Metzinger; [2022]
    Keywords : Cryogenic propulsion; Electrical pump; Operating domain;

    Abstract : The Exploration Company is a French and German start-up that develops and operates Nyx, anorbital vehicle that also has a lunar version. This thesis focuses on the modeling and simulationof the o-design operation of the cryogenic engine of Nyx. READ MORE

  5. 4. Preliminary Power Analysis of an Unmanned Aerial Vehicle : Featuring Integrated Electric Ducted Fans

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Conny Yu; Ruben During; [2022]
    Keywords : Power Analysis; Propulsion; Electric Ducted Fans; Blended Wing Body; Unmanned Aerial Vehicle; Green Raven;

    Abstract : With increasing focus on climate change more research for net-zero emission are being made in the aviation industry.This project focuses on electric propulsion on a unmanned aerial vehicle (UAV) with a blended wing body (BWB) design. READ MORE

  6. 5. Life Cycle Assessment of Electric Road Systems - Climate impact in comparison with battery electric vehicles, biogas vehicles and fuel cell electric vehicles

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Ebba Söderström; Emanuel Bengtsson; [2022]
    Keywords : Electric road systems; Elonroad; life cycle assessment; rail; feed-in station; pick-up; on-board charger; climate impact; global warming potential; articulated lorry; lower medium car; bus; Technology and Engineering;

    Abstract : One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where vehicles are charged dynamically.
