1. Slagkraft och tryckkraft från friktionsbaserat hängande conveyor-system
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Mål: En rapport har utförts för att undersöka om vad den aktuella slagkraften samt tryckkraft är från OCS två overhead conveyor-system, OCS 150 och OCS 500. Slagkraften uppmättes för att kartlägga en av de krafter som genereras från systemets olika kombinationer av fjädrar, vikt och hastighet. LÄS MER
2. Airspeed estimation of aircraft using two different models and nonlinear observers
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : When operating an aircraft, inaccurate measurements can have devastating consequences. For example, when measuring airspeed using a pitot tube, icing effects and other faults can result in erroneous measurements. LÄS MER
3. 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, rörelsemekanikSammanfattning : 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
4. Design, production, and validation of a vacuum arc thruster for in-orbit proximity operations
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Vacuum arc thrusters offer a relatively simple and cheap form of satellite propulsion, especially suitable for nanosatellites such as CubeSats or even smaller. This thesis focuses on vacuum arc thruster design considering the thruster’s manufacturing, assembly and integration into the spacecraft, and proposes a new anode geometry easing thruster production.

5. Analysis of Hall effect thrusters using Hybrid PIC simulations and coupling to EP plume
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : 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.
