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

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Simone Guietti; [2024]
    Keywords : Pintle injector; space propulsion; space engineering;

    Abstract : ”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. READ MORE

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

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Rymdteknik

    Author : Valentin Miquel; [2020]
    Keywords : Multiengine Feeding System;

    Abstract : 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. READ MORE
