Electromagnetic pulse accelerator of projectiles
Žamberský, Jan ; Jirák, Josef (oponent) ; Frk, Martin (vedoucí práce)
This work focuses on using magnetic field to accelerate projectile in a device called coilgun. It consists of two parts, first is theoretical discussing magnetism and its use, the other part is about coilgun itself, its benefits and drawbacks. Followed by series of measurements on two experimentally built coilguns and trying optimize it to achieve best results. First part discusses multiple topics. In the beginning, there is a small section defining magnetic field and other constants and phenomenons connected with it. Next two chapters are focused on different types of material, mainly ferromagnetics, how they react to magnetic field and what parameters we can follow, followed by a list of several applications of magnetic field in different areas of human society. The second part describes main principle of coilgun and how the prototypes were made. Measurements on a first prototype consist of trying different materials for projectile, various dimensions of it and benefits of using external shell for accelerating coil. There is also a chapter discussing velocity measurement of a projectile. Second prototype is trying to avoid all the flaws, which were found on the first prototype and find a benefits of using multiple acceleration stages.

Analýza dynamiky a výroba prototypu Gaussovy pušky
Militký, Ondřej ; Musil, Filip (oponent) ; Rubeš, Ondřej (vedoucí práce)
Tato práce se zabývá popisem principu Gaussovy pušky. Je zde popsán fyzikální princip, na kterém zařízení funguje, provedení konstrukce a její výhody a omezení. Dále je vytvořen výpočtový model v prostředí Matlab Simulink, který simuluje chování projektilu během výstřelu. Na základě tohoto modelu je navržen a zkonstruován prototyp Gaussovy pušky. Prototyp je následně testován a porovnáván s výpočtovým modelem pro určení celkové účinnosti vytvořené pušky.
