  1. 1. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :David Fredouelle; [2023]
    Nyckelord :Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

    Sammanfattning : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions. LÄS MER

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

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

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

    Sammanfattning : 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. LÄS MER

  4. 3. Numerical Approach to the Design and Optimisation of a Bi-Propellant Pintle Injector

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Erik Andersson; [2022]
    Nyckelord :pintle injector; optimisation; propulsion; liquid propellant;

    Sammanfattning : Rocket propulsion is of vital importance for space travel. New innovations are continuously developed in order to facilitate the demand of the rapidly evolving space sector. Recently a focus on reusable rockets has appeared due to the economical and environmental benefits they bring. LÄS MER

  5. 4. Design and Implementation of Downtime Management System for Assembly Production : Software specification and practical challenges

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gustav Dowling; [2022]
    Nyckelord :Overall equipment efficiency; Assembly manufacturing; Automotive Industry; Supervisory Control and Data Acquisition; Information Systems; Downtime management; Overall Equipment Efficiency; Monterings produktion; Fordonsindustri; Supervisory Control and Data Acquisition; Information Systems; Stopptidshantering;

    Sammanfattning : The usage of information technology (IT) systems has become an integral part of assembly manufacturing. Supervisory control and data acquisition (SCADA) systems are widely used in order to control production cycles and monitor equipment such as conveyor belts. LÄS MER

  7. 5. Optimization of solid-phase extraction (SPE) as sample preparation for oil samples in forensic investigations.

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Aamanda Chang; [2021]
    Nyckelord :Solid-phase extraction SPE ; heavy fuel oil HFO ; fingerprint; polycyclic aromatic hydrocarbons PAHs ; biomarkers.;

    Sammanfattning : Oil spills, especially in water have happened throughout the years. The consequences from this kind of incident have always been a threat to marine life and take a lot of money and time to clean up. LÄS MER
