  1. 16. A study on Hall Effect Thruster exhaust plume simulation

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

    Författare :Andrius Sukys; [2020]
    Nyckelord :;

    Sammanfattning : The results of the attempt to simulate a 1,5 kW-class Stationary PlasmaThruster (SPT) type Hall Effect thruster exhaust plumes are presented.This work focuses on the simulation of the near field region since acharged particle can directly affect the other systems of the spacecraft,such as solar panels, camera etc. LÄS MER

  3. 17. Development and testing of algorithms for optimal thruster command distribution during MTG orbital manoeuvres

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Lars Sprengelmeyer; [2020]
    Nyckelord :linear programming algorithms; linear optimization; thruster command distribution; thruster control; Simplex; Karmarkar s method; minimum power controller; minimum flow rate controller; minimum control authority;

    Sammanfattning : An accurate satellite attitude and orbit control is a key factor for a successful mission. It guarantees for example sun acquisition on solar panels, fine pointing for optimal telescope usage or satellite lifting to reach higher orbits, when required. LÄS MER

  4. 18. Experimental Verification of BP-HiPIMS Thrusters

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

    Författare :David Mainwaring; [2020]
    Nyckelord :Electric propulsion; BP-HiPIMS; Space propulsion; Elektriskframdrivning; BP-HiPIMS; Rymdframdrivningssystem;

    Sammanfattning : The ion acceleration process in Bipolar High Power Impulse Magnetron Sputteringis investigated for use in a novel space propulsion system - the BP-HiPIMS thruster.The interest for BP-HiPIMS has recently been growing within the area of thin filmdeposition due to the theorised acceleration of target ions caused by the reversedpulse following the regular HiPIMS pulse.

  5. 19. The I2T5 : Enhancement of the Thermal Design of an Iodine Cold Gas Thruster

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Roger Michael Pereira; [2020]
    Nyckelord :Cold gas thruster; I2T5; CubeSat propulsion; thermal analysis; heat transfer; thermal resistance; orbital heat fluxes;

    Sammanfattning : The I2T5, an iodine-propelled, cold gas thruster, developed by ThrustMe, France, is the first of its kind to make it successfully to space. Due to its simple, reliable and cost-effective design, it is a suitable propulsion system for CubeSat missions with low delta-V (ΔV) requirements. LÄS MER

  7. 20. A Xenon Collisional Radiative Model for Electric Propulsion Application : Determining the electron temperature in a Halleffect Thruster

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

    Författare :Tarek Ben Slimane; [2020]
    Nyckelord :;

    Sammanfattning : Hall effect thrusters (HET) that rely on xenon as a propellant are widely adoptedtoday for their efficiency. To understand the kinetics of the xenon plasma dischargein the thruster, we developed a collisional radiative model for xenoninspired by the work of Karabadzhak et al. [1]. LÄS MER
