  1. 1. 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

  2. 2. 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

  3. 3. 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

  4. 4. Analysis of Hall effect thrusters using Hybrid PIC simulations and coupling to EP plume

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :David Villegas Prados; [2020]
    Nyckelord :Hallis; SPIS; EP; plume; hybrid PIC; Hall effect; HET; inside channel; plume expansion;

    Sammanfattning : In the last 30 years, numerical models have been developed to properly analyze Hall eect thrusters (HET),leading to a bridge between analytical prediction/empirical intuition and experiments. For companies in thespace sector, these codes serve to much more than simply simulating the thruster, but it provides a fast, cheapand reliable tool for processes such as validation and verication procedures, as well as for technical developmentof the thruster.

  5. 5. EM emissions test platform implementationfor satellite electric propulsion systems andelectronic subsystems

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Siiri Talvistu; [2019]
    Nyckelord :Electromagnetic compatibility; electromagnetic emissions; compliance; ion thruster;

    Sammanfattning : Modern gridded ion thrusters for CubeSats operate by generating high power and canpose challenging problems with Electromagnetic Interference (EMI). In order to verifycompatibility with neighbouring equipment, strict standards such as the militarystandard MIL-STD-461G, are required to be followed to achieve ElectromagneticCompatibility (EMC).
