Merjenje navora na propelerski gredi med letom : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoVadnu, MartinV magistrskem delu je opisana zasnova in izvedba merilnega sistema, ki omogoča meritev navora na propelerski gredi med letom. Na podlagi meritev navora lahko ob znanih lastnostih letala določimo ... vrednost potiska v horizontalnem uravnovešenem letu. Na podlagi izbire konfiguracije letala, motorja in propelerja smo izvedli preračun in optimizacijo gredi, ki je omogočala namestitev uporovnega merilnega lističa in pripadajoče merilne opreme za meritev navora. Izveden je bil statični preizkus gredi na maksimalno obremenitev ter vpliv prečne sile in sile potiska na meritev navora. Z znano merilno karakteristiko sistema smo izvedli preizkus statičnega potiska in preizkus v letu za tri različne nastavitve kotov krakov propelerja. Meritve navora v letu so bile uspešne, vendar z zelo slabo ponovljivostjo pri večini meritev. Računska določitev učinkovitosti propelerja je bila odvisna od natančnosti meritev, zato so bili tudi rezultati učinkovitosti večinoma neponovljivi. Metoda se je izkazala za izvedljivo, a ima pomanjkljivosti, ker na prostem ni mogoče zagotoviti konstantnih pogojev.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
