11. Lättgaskanonens innerballistik : Teori, simulering och parameterstudie
Master-uppsats, KTH/Maskinkonstruktion (Avd.)Sammanfattning : En lättgaskanon är en typ av kanon som används vid experiment där mycket snabba förlopp är av intresse, till exempel hypersonisk strömning och höghastighetskollisioner. Kanontypen når betydligt högre hastigheter än en konventionell kanon då projektilen accelereras genom eldröret av en gas med låg molekylmassa som vätgas eller helium istället för krutgaser. LÄS MER
12. Modeling and Evaluation of Turret Control Systems for Main Battle Tanks
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The aim of the thesis was to implement and compare control methods in a model of a main battle tank. Three controllers were implemented in a two axis gimbal model and their performances were compared. LÄS MER

14. Design Upgrades, Reliability Testing and Implementation of Engineering Grade Thermoplastics in Prusa MMU2s
Master-uppsats, Jönköping University/JTH, Material och tillverkningSammanfattning : This paper studies the two aspects of current problems that plagues the Prusa i3 MK3sprinters in possession of JTH and how to resolve them; to be able to get a reliable printoutputs from engineering grade materials apart from conventional materials like PLAand PETG. The second aspect being the implementation of multi material module 2. LÄS MER
15. Mapping and characterisation of surface damage and wear mechanisms in gun barrels : Gun barrels exposed to cyclic thermo-mechanical loading
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Gun barrels are an important component in advanced defence systems. The gun barrels are used for direct and indirect fire and the material of the gun barrel is exposed to great strains and high temperatures. This sets high demands on the material of the gun barrel. During firing the gun barrel can be damaged. LÄS MER
