20.500.12556/RUL-155723 Odstranjevanje naelektrenega prahu z vesoljskih oblek Removal of charged dust from spacesuits Človek običajno ne pomisli, da bi lunin prah lahko bil nevaren in da je to eden izmed glavnih razlogov, zakaj že več kot 50 let nismo stopili na Luno. Pričakovali bi, da je hoja po luninem površju enaka kot hoja po peščeni plaži, vendar je tamkajšnja situacija veliko slabša, kot bi si mislili. Ker je površje Lune izpostavljeno nevarnemu Sončevemu vetru in tam ni atmosfere, imajo prašni delci določene lastnosti, ki močno otežijo delo astronavtov in opreme. V diplomskem delu najprej raziščem fizične lastnosti luninega regolita, zakaj je tako abaziven in škoduje astronavtskim oblekam. Opišem tudi električen naboj, ki je prisoten na površju Lune in je hkrati glavni razlog, zakaj je lunin prah tako moteč in se ga je težko znebiti. Kasneje proučim metode, kako se znebiti luninega prahu z vesoljskih oblek in ostale opreme. Podrobno opišem kako deluje sistem SPIcDER, ki bo uporabljen v prihodnjih astronavtskih oblekah, in kakšna je učinkovitost tega sistema ter kako ga vgraditi v že obstoječe obleke, kjer se podam tudi v materiale uporabljene za ta sistem. Delo se konča z varnostmi pomisleki in pa seveda kakšna je povezava Luninega prahu s prahom drugih planetov oz. lun. Na koncu se še doda, kaj nas lahko še čaka v prihodnosti glede prihajajočih Luninih misij. It's not usually thought that lunar dust could be dangerous, and it's one of the main reasons why we haven't set foot on the Moon for more than 50 years. You would expect that walking on the lunar surface would be the same as walking on a sandy beach, but it turns out that the situation there is much worse than you would think. Because the surface of the Moon is directly exposed to the dangerous solar wind, and the lack of atmosphere there, dust particles have certain properties that make it very difficult for astronauts and equipment to function. In my thesis I first investigate the physical properties of lunar regolith, why it is so abrasive and causes damage to astronauts' suits. I also describe the electrical charge present on the surface of the Moon, which is the main reason why lunar dust is so annoying and difficult to get rid of. Later, I look at methods to get rid of lunar dust from space suits and other equipment. I describe in detail how the SPIcDER system works, which will be used in future astronaut suits. I will also discuss the performance of this system and how to integrate it into existing suits, where I will also go into the materials used for this system. The work ends with safety considerations and, of course, what is the relationship of lunar dust to dust from other planets or moons. Finally, there is a look at what the future may hold for us in terms of upcoming Lunar missions. regolit naboj karbonske nanocevke magnetosfera SPIcDER regolith charge carbon nanotubes magnetosphere SPIcDER true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-04-12 14:05:01 2024-04-12 14:05:12 2024-04-18 08:30:59 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 61170 192589827 Koceli_Filip_-_Odstranjevanje_naelektrenega_prahu_z_vesoljskih_oblek.pdf Koceli_Filip_-_Odstranjevanje_naelektrenega_prahu_z_vesoljskih_oblek.pdf 1 CCBE5BD1240EF0A6D84B58B0A506769D b9da8d3d174bbcbb4ff52dedf971504a70ff6351ff8d03841bd162406b2457f0 eace3a10-f8c4-11ee-859e-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182781 Fakulteta za elektrotehniko 0 0 0
