Abstract

Analiza utjecaja oblikovanog napadnog ruba na krutost cijelog krila. Dvije vrste modela krila su uspoređene, bazirane na grednim i plošnim (ljuskastim) konačnim elementima. Jedna grupa modela ima oblikovani napadni rub a druga grupa modela ima samo torzijsku kutiju. Gredni modeli su pripremljeni prema plošnim (ljuskastim) konačnim elementima koristeći FEMAP, Solidworks i TORO programe, tako da imaju približno jednake karakteristike krutosti.Tri vrste opterećenja su primjenjene na pripremljene modele, čisto savijanje, čista torzija i kombinirano savijanje i torzija. Relevantni pomaci za svako opterećenje su uspoređeni duž raspona krila.

Abstract (english)

The influence of the morphing LE structure on the stiffness of a whole wing was analysed. Two types of wing models were compared based on finite element method (FEM) shell and beam models, one set with morphing leading edge mechanism and one set with only wing box (WB) structure. Beam models were prepared based on shell models using FEMAP, Solidworks and TORO software. Three load cases were applied to the models prepared, pure bending, pure torsion and combined bending and torsion. Structural displacements were obtained and results presented across a wing span for each load case.
