Abstract

U ovom radu je napravljena numerička analiza čvrstoće dviju konstrukcija krila visoke vitkosti u programu Abaqus/Standard. Napravljen je pregled elemenata konstrukcije krila i njihovih potencijalnih izvedbi te materijala koji se koriste za njihovu izradu. Opisani su kompozitni materijali i razlozi njihovog korištenja u ovim izvedbama. Vođeno je računa o načinu i jednostavnosti izvedbe kao realnom budućem projektu. Objašnjene su postavke numeričkog programa Abaqus/Standard kao i način prijenosa modela iz CAD programa u ovom slučaju Solidworks-a. Prikazani su rezultati analiza i uspoređene mase sličnih letjelica.
Ukazalo se na problematiku proračuna čvrstoće i konstruiranja pri graničnom opterećenju ovakvih letjelica i potrebu za nekim drugim načinom konstruiranja za ovaj tip letjelice koji sigurno i postoji u industriji, ali se obično drži kao tajna.

Abstract (english)

In this thesis, a numerical analysis of the strength of two high-aspect wing structures was performed in the Abaqus / Standard. Also, an overview was made of the structural wing elements and their potential performances with the materials used. Composite materials and the reasons for their use are described. Structural design considerations and its ease was taken into account as a realistic future project. Numerical settings of the Abaqus / Standard are explained, as well as the way of transferring the model from the CAD program in this case Solidworks. The results of analyzes and comparisons of masses of similar aircraft are presented. The issue is made known of designing such aircraft and the need for another way of designing, which certainly exists in the industry but is usually kept as a secret.
