  1. 1. Development of a System to Quantify Coking in Rocket Nozzle Cooling Channels

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Adam Parks; [2022]
    Keywords : methane; pyrolysis; reusable; carbon deposition; ozone cleaning; rocket engines; cooling channels; borescope; metan; pyrolys; återanvändbar; koldeposition; ozon-rening; raketmotorer; kylkanaler; boreskop;

    Abstract : Liquid methane is becoming an increasingly attractive rocket propellant due to its high performance characteristics and potential to support in-situ resource utilisation. Methane, however, when heated, can thermally decompose in a process known as pyrolysis. READ MORE

  3. 2. SSRT of 10-4 FeCrAl in LBE and Pb to Characterize Liquid Metal Embrittlement Effects

    University essay from KTH/Fysik

    Author : Daniel Stein; [2022]
    Keywords : Liquid Metal Embrittlement; Lead; Bismuth; Lead-Bismuth Eutectic; Slow Strain Rate Testing;

    Abstract : In this work the susceptibility of Fe-10Cr-4Al steel to liquid metal embitterment (LME)in low oxygen environment was investigated. slow strain rate testing (SSRT) wereconducted on 10-4 FeCrAl steel in a stagnant lead from 340-480◦C, lead-bismutheutectic (LBE) from 140-450◦C and lead-bismuth mixture at 375◦C with increasingbismuth content from 0.

  4. 3. Identifying risks of AdBlue spray on stainless steel surfaces

    University essay from KTH/Kemiteknik

    Author : Evelina Tvinne Flyg; [2021]
    Keywords : Urea; Stainless steel; SCR; Deposit; Corrosion; Urea; rostfritt stål; SCR; Avlagring; Korrosion;

    Abstract : Utsläppskontroll, reglerad av allt strängare lagstiftning, ställer höga krav på utvecklingen av noggranna efterbehandlingssystem för avgaser. När det gäller utsläpp från dieselmotorer utgör NOx-minskning en av de största utmaningarna. För tunga fordon tacklas denna utmaning ofta genom ett SCR-system. READ MORE

  5. 4. Design of a Level Sensing System for the Propellant Tank of a Microlauncher

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Robin Scholtes; [2021]
    Keywords : Level Sensing; Cryogenic; Microlauncher; Liquid Oxygen; Nivåavkänning; Kryogen; Mikrobärraket; Flytande Syre;

    Abstract : The present report aims to show the development process of a liquid level sensing system for the use within the propellant tanks of a launch vehicle. Whereas many recent launchers use discrete level sensing systems to indicate the amount of fuel on defined spots like fill-stop and engine cut-off, in this report a continuous capacitance based sensor probe is described.

  6. 5. Evaluation of liquid air as an energy storage alternative

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Tomas Högberg; Martin Tholander; [2018]
    Keywords : Liquid air; LAES; Energy storage; efficiency; Flytande luft; LAES; Energilagring; verkningsgrad;

    Abstract : As renewable, intermittent energy sources are expected to increasingly replace fossil based energy, energy storage technologies are crucially important in achieving the goal of fossil free energy, a cornerstone of sustainable development. Liquid air energy storage (LAES) is a novel technology that liquefies air when excess electricity is available. READ MORE
