SažetakNestacionarni, uzdužni aerodinamički derivativi subsoničnih aviona proizvoljne konfiguracije mogu se proceniti korišćenjem metoda konačnih elemenata baziranih na metodi rešetke dubleta (Doublet Lattice Method - DLM), teoriji vitkih tela (Slender Body Theory SBT) i metodi zamena (Method of Images MI). Primenom navedene metodologije razvijen je softverski paket DERIV. Rezultati dobijeni programom DERIV testirani su na primerima HA21A i HA75H iz NASTRAN-a. Postignuto je dobro slaganje rezultata.
