Sažetak
U radu je prikazana spoljašnja šestokomponentna aerovaga projektovana i izrađena u Vojnotehničkom institutu u Beogradu. Prikazana aerovaga spada u grupu spoljašnjih aerovaga sa platformom. Aerodinamičko opterećenje koje deluje na model u radnom delu aerotunela prenosi se na na šest mernih ćelija. Prikazane su matematičke relacije između aerodinamičkog opterećenja i sila izmerenih u mernim ćelijama. Sve merne ćelije su sa folijskim mernim trakama. U radu su prikazani i rezultati etaloniranja aerovage. U toku etaloniranja opterećenja su unošena pomoću tegova.
