Abstract

Zadatak ovog završnog rada je numerički odrediti utjecaj suženja krila na raspodjelu naprezanja
u elementima konstrukcije aviona. Tijekom analize utjecaja suženja krila na raspodjelu
naprezanja mijenja se samo omjer suženja krila te se tako analiziraju naprezanja i pomaci
pojedinih varijanata krila. Geometrija razmatranih konstrukcija krila modelirana je u programu
Solidworks, a zatim poslije uvezena u Abaqus/Standard® program u kojem su provedene
numeričke analize. Krilo je trapezno te nema kuta strijele. Letjelica koja je korištena kao
referentna je Cessna 172 čije su dimenzije korijenske i vršne tetive, raspona i referentne
površine krila korištene u modeliranju i proračunu. U modeliranju i proračunu razmatranih
konstrukcija krila korištena su pojednostavljenja i pretpostavke koja su detaljno objašnjena u
tekstu.

Abstract (english)

The task of this Bachelor's thesis is to numerically determine the influence of wing taper on
stress distribution in aircraft structural elements. During the analysis of the influence of wing
taper on stress distribution, only the wing taper ratio changes, and thus stresses and
displacements of each wing structure variants are analyzed. The geometry of the considered
wing structures is modeled in Solidworks software, and then imported into the
Abaqus/Standard® software for numerical analysis. The analyzed wing is trapezoidal and has
no sweep angle. The aircraft used as a reference is the Cessna 172, whose root and tip chord
dimensions, wingspan, and reference wing area are used in modeling and stress analysis.
Simplifications and assumptions used in modeling and analysis of the considered wing
structures are detailed in the text.
