    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

  3. 12. Exterior ballistics analysis for rocket propelled KE-penetrator - A conceptual simulation study within fluid mechanics and flight mechanics

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Emil Wegberg; [2022]
    Keywords : Exterior ballistics; fluid mechanics; high-speed aerodynamics; CFD; RANS; conceptual design; Ytterballistik; strömningsmekanik; höghastighetsaerodynamik; CFD; RANS; konceptuell design;

    Abstract : This study has investigated the conceptual feasibility of a rocket propelled kinetic energy penetrator (KEP), designed for the handheld recoilless rifle Carl-Gustaf® 84 mm calibre system, from an exterior ballistics perspective. The methodology is based upon evaluating the aerodynamic properties of different conceptual design proposals through CFD-simulations and then performing trajectory analysis to assess their exterior ballistic performance.

  4. 13. 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

  5. 14. Electric propulsion of satellites as an alternative for implementation of a sunshade system

    University essay from KTH/Fysik

    Author : Maheen Arfan; Isabelle Bonnier; [2022]
    Keywords : Geoengineering; Sunshade system; Electric propulsion; Orbital mechanics; Sub-lagrange;

    Abstract : As an alternative solution to global warming, this thesis explores the possibility of aspace-based geoengineering scheme that may prove worthwhile to implement in parallel toother environmental efforts that help mitigate impact of climate change. One suggestionof a geoengineering solution is deploying a large number of sunshades in the vicinity ofthe first Lagrange point of the Sun-Earth system, and this prospective sunshade projectwould serve to shield Earth from incident solar radiation.

  6. 15. Design of a State-Of-The-Art Test Facility for Rocket Engines

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Akash Raja Meghavath; [2022]
    Keywords : Rocket architectures; oxidizer feed system; layout plan; safety precautions safety standards; test bed stand; static tests;

    Abstract : The development of innovative propulsion systems requires testing in suitable facilities that reveal the efficacy of design models and allow for design refinement. The qualification process starts from ground tests and ends in vacuum chambers. READ MORE
