20.500.12556/RUL-165360 Sistem za nadziranje mejne plasti na letalskem krilu s premikajočo površino Moving surface system for controlling the boundary layer on an aircraft wing Na področju letalstva se snovalci in inženirji od samega začetka letalstva trudijo, da bi z vsako novo idejo nadgradili uspehe svojih predhodnikov. Z vsakim napredkom letalstvo postane cenejše in bolj dostopno širšim skupnostim. V istem duhu smo se v tem diplomskem delu namenili testirati sistem, ki bi nudil morebitne nove vpoglede v obnašanje mejne plasti zraka, ki potuje čez krilo. Zasnovali in konstruirali smo model, krila s sistemom za nadzor mejne plasti, v obliki tekočega traku, ki smo ga preizkusili v vetrovniku, pri različnih hitrostih zračnega toka in raznih relativno nizkih vpadnih kotih. Uspelo nam je doseči približke idealnih teoretičnih koeficientov upora za naš aeroprofil na realnem krilu. Pri določenih vpadnih kotih in hitrostih nam je tudi uspelo izboljšati aerodinamski izkoristek. Since the early days of aviation, designers and engineers have endeavoured to build on the successes of their predecessors with every new idea. With every advance, aviation becomes more affordable and more accessible to a wider section of the population. With this in mind, this work tested a system that could potentially provide new insights into the behaviour of the boundary layer of air moving over a wing. We designed and constructed a model wing with a boundary layer control system in the form of a conveyor belt, which we tested in a wind tunnel at different flow velocities and relatively low angles of attack. We succeeded in approximately achieving the theoretically ideal drag coefficients for our airfoil on a real wing. At certain angles of attack and speeds, we also succeeded in improving the aerodynamic efficiency. aeroprofil vzgon upor mejna plast vetrovnik tekoči trak airfoil lift drag boundary layer wind tunnel conveyer belt true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-12-04 08:30:46 2024-12-04 08:30:50 2025-01-22 13:14:12 0000-00-00 00:00:00 2024 0 0 XX, 48 str. 2024 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 629.7:531:531.49(043.2) 270347 223489027 38353.pdf 38353.pdf 1 8E4C2836C12FEADF92E27AEBAD656689 20e82eaa1725481651c6e6ba06077668f5a49cfe5e458d2e16f3818719055742 3e9c50f8-b211-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196490 Fakulteta za strojništvo 0 0 0
