| description | U radu su prikazani rezultati merenja aerodinamičkih sila i momenata, kao i vizualizacija strujanja u graničnom sloju na krilima i krmilima modela laserski vođene bombe. Ispitivanje je izvršeno u aerotunelu T-38. Analiziranje uticaj rastojanja vrha konusa tela, u odnosu na sekciju krmila, na aerodinamičke karakteristike modela za dva Mahova broja M∞ = 0,8 i 0,9 i otklon krmila δ=15°. Normalne sile koje se javljaju na modelu i krmilu merene su unutrašnjim aerovagama. Dobijeni rezultati merenja normalne sile na modelu i posebno na krmilu povezani su sa rezultatima vizualizacije strujanja metodom uljnih premaza. Priložene fotografije vizualizacije strujanja ilustruju promene strujanja oko modela i potvrđuju rezultate aerodinamičkih merenja. / Aerodynamic test results and boundary layer flow visualization on the wings and fins of laser guided bomb model are presented in this article. Test was performed in the T-38 wind tunnel. Influence of fin position relative to conic top of the model on aerodynamic characteristics was analyzed. Analysis was performed on aerodynamic characteristics of the model for two Mach numbers M∞ = 0,8 and 0,9 and fin deflection δ=15°. Normal forces present on the model and fin were measured by internal strain gauge balances. Obtained test results of normal force on the model and especially on the fin were associated with flow visualization results, which were performed by oil emulsion method. Presented images of flow visualization show changes of the flow around the model and confirm the results of the aerodynamic measurements. |
