1. 1. Development of Test Methodologies and Setups for Thrust Measurements of Cold Gas Micro-thrusters for CubeSats

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Aleksander Kipiela; [2022]
   Nyckelord :Thrust measurements; cold gas propulsion; micro thrusters; hanging pendulum; CubeSat; Dragkraftsmätning; kallgasframdrivning; mikrodysor; hängande pendel; CubeSat;

   Sammanfattning : Measuring the thrust of cold gas micro-thrusters, due to the small magnitude of the generated force, is a challenging task, and to obtain satisfying quality of results usually careful adjustments of the setup has to be performed. The work presented in this paper aims at improving the quality of such measurements at the GomSpace Sweden company. LÄS MER

3. 2. 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.
