Analiza koeficijenta momenta valjanja raketa sa olučastim krilima
Vojnotehnički institut - VTI, Beograd
Ključne reči: arodinamika rakete; olučasto krilo; momenta valjanja; aerodinamički koeficijenti; aerodinamički derivativi
Sažetak
Merenje koeficijenta momenta valjanja u aerotunelu, urađeno je za dva modela raketa sa olučastim krilima i jedan model rakete sa ravnim krilima. Merenje koeficijenta momenta valjanja za sve modele urađeno je za dva ugla ugradnje krila ( 0o i 0.8o). Izmerene vrednosti koeficijenta momenta valjanja usklađene su sa polinomom četvrtog stepena po napadnom uglu. Pokazano je da je koeficijent momenta valjanja raketa sa olučastim krilima, pri nultom napadnom uglu, jednak zbiru koeficijenta momenta valjanja usled krivine olučastih krila i koeficijenta momenta valjanja ekvivalentnih ravnih krila postavljenih pod istim uglom ugradnje kao i olučasta krila.
