  1. 11. Investigation of robustness of a SiC MOMS pressure sensor in high pressure/temperature operation conditions

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

    Författare :Monika Sieczka; [2022]
    Nyckelord :;

    Sammanfattning : Rigorous environmental policies and the need for higher fuel economy continuously demand new innovations in the combustion process of automotive engines. Consequently, there is an increasing necessity for active monitoring of the combustion event, and therefore, microsystems have started coming into play. LÄS MER

    Nyckelord :;

    Sammanfattning : The Exploration Company is a French and German start-up that develops and operates Nyx, an orbital vehicle that also has a lunar version. This thesis focuses on the modeling and simulation of the off-design operation of the cryogenic engine of Nyx. LÄS MER

  4. 13. Fluid flow features in swirl injectors for ethanol fueled rocket : - Analysis using computational fluid dynamics

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Emil Vejlens; Dylan De Jourday; [2022]
    Nyckelord :Fluid Mechanics; Rocket Science; Fuel injectors; Computational Fluid Dynamics; Swirling Flows; Fuel Mixing;

    Sammanfattning : A swirl injector for a rocket engine being developed by \emph{AESIR} (Association of EngineeringStudents in Rocketry) was simulated with different geometric parameters. The swirl injector is usedto atomize the ethanol used as fuel and to create a spray that mixes well with the oxidizer withinthe combustion chamber. LÄS MER

  5. 14. Parametric study on hybrid rocket propulsion system performance measured by the system specific impulse

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Adam Bussmann; [2022]
    Nyckelord :Hybrid; Hybrid propulsion; Hybrid propulsion system; System specific impulse;

    Sammanfattning : Hybrid rocket motors have become of great international interest during the last couple of years. A hybrid rocket motor is propelled by the use of a solid fuel and a liquid oxidizer. The fundamental principle of the hybrid propelled system is that the liquid oxidizer is injected into a combustion chamber to enable the combustion of the solid fuel. LÄS MER
