  1. 1. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  3. 2. Transportation Study of Release from a Space Elevator to Cislunar Space

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

    Author : Daniel Griffin; [2023]
    Keywords : Space Elevator; Cislunar Space; Mass Transportation; Astronaut Safety; Apex Anchor; Rymdhiss; Cislunar-rymden; Masstransport; Astronautsäkerhet; Apex-ankaret;

    Abstract : To leave Earth’s gravity well and ascend into Cislunar space takes ingenuity, and the engineering feats of many. Now to propel humanity further into space, rockets will need assistance to provide the large requirements of mass to be used for space structures. READ MORE

  4. 3. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Vikramjeet Das; [2023]
    Keywords : rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

    Abstract : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. READ MORE

  5. 4. Developing a Mathematical Model of a Nuclear Thermal Rocket Engine

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Anton Blomqvist; [2023]
    Keywords : Nuclear Thermal Rocket; Nuclear Rocket; Rocket; Mathematical Model;

    Abstract : Renewed enthusiasm for space exploration brings more ambitious missions to light butthe constraints of chemical rockets put imposing limits on what is feasible. Nuclearthermal rockets provide an attractive and efficient alternative to shorten travel timesand increase payload. READ MORE

  6. 5. Analysis and Design of a Microgravity Drop Tower

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Tristan Edwards; [2023]
    Keywords : drop tower; microgravity;

    Abstract : A drop tower is a device that produces a microgravity environment by allowing an experiment to free fall for a short period of time, usually less than 10 seconds. Certain types of drop towers are also capable of reproducing the gravitational conditions of other celestial bodies, such as Lunar and Martian gravity. READ MORE
