  1. 1. Preliminary Design and Conceptual Analysis of an Electrically Actuated Pintle Injector

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Simone Guietti; [2024]
    Nyckelord :Pintle injector; space propulsion; space engineering;

    Sammanfattning : ”The Eagle has landed”. With this words, astronaut Neil Armstrong, together with astronaut Edwin ”Buzz” Aldrin, confirmed the safe landing on the Moon of the Apollo11 on July 20th, 1969. This achievement would have never been possible without the engineering behind the construction of the Moon lander. LÄS MER

  3. 2. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :WULLSCHLEGER LÉA; [2023]
    Nyckelord :Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Sammanfattning : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. LÄS MER

  4. 3. Creation of a set of tools enabling rapid system engineering loops for small reusable launchers

    Master-uppsats, KTH/Rymdteknik

    Författare :Louise Terrien; [2021]
    Nyckelord :Reusable Launchers; System Engineering; Trajectory; Kick-Stage; Återanvändbara Bärraketer; Systemteknikslingor; Uppskjutningsbana; Kick-Stage;

    Sammanfattning : The 2010's have seen many changes happening in the launcher world: private players have emerged increasing competition for the traditional launch operators and the development of reusable launcher allowing a decrease in launch cost. The satellite market has also evolved with the appearance of nano-satellites and the development of satellite constellations. LÄS MER

  5. 4. Propellant Feeding System of a Liquid Rocket With Multiple Engines

    Master-uppsats, KTH/Rymdteknik

    Författare :Valentin Miquel; [2020]
    Nyckelord :Multiengine Feeding System;

    Sammanfattning : Multiengine first stages are the new trend in recent rockets. Reusability and an oxygen/methane based engine complete this picture. ArianeGroup wants to develop its own rocket following these principles. This thesis presents the study of the feeding system for a seven Prometheus engine rocket. LÄS MER

  7. 5. Thermal gas radiation modelling for CFD simulation of rocket thrust chamber

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Rejish Lal Johnson Samee Lal; [2019]
    Nyckelord :Gas radiation; thrust chamber; CFD; heat transfer; Rocflam3; methane; Gasstrålning; tryckkammare; CFD; värmeöverföring; Rocflam3; metan;

    Sammanfattning : Methane and oxygen are a promising propellant combination in future rocket propulsion engines mainly due to its advantages like reusability and cost reduction. In order to have a comprehensive understanding of this propellant combination extensive research work is being done. LÄS MER
