Abstract
Tema diplomskog rada je dizajn i razrada mikrolake ovjesne jedrilice s motorom i numerička analiza te konstrukcije. Povijest zmajarstva, izgled konstrukcije motornih ovjesnih jedrilica te tehnike upravljanja i leta jedrilica opisani su u uvodu rada. Nakon uvida u stanje tržišta i analizom postojećih proizvoda, definirane su karakteristike koje mikrolake ovjesne jedrilice moraju imati te su prikazana i analizirana rješenja za pojedine konstrukcijske zahtjeve. Na temelju toga osmišljen je koncept mikrolake ovjesne jedrilice koji je modeliran korištenjem programskog paketa SolidWorks. Koncept je u nastavku rada detaljno prikazan te je opisan način sklapanja i rastavljanja konstrukcije. Nabrojane su važnosti pravilnog dimenzioniranja cijevi konstrukcije i prikazan je položaj pilota tijekom leta motornom ovjesnom jedrilicom koristeći programski paket Catia V5. U nastavku rada, korištenjem programskog paketa Abaqus, provedena je numerička analiza konstrukcije osmišljenog koncepta. Prvo su provjerena naprezanja tijekom leta za više slučajeva opterećenja. Nakon toga analizirana je čvrstoća konstrukcije prilikom slijetanja kada dolazi do udarnog opterećenja. Na temelju numeričke analize zaključeno je da su pojedine cijevi predimenzionirane te je nakon promjene promjera i debljina stijenki tih cijevi provedena još jedna analiza naprezanja konstrukcije. U završnom poglavlju dan je zaključak na temelju provedenih numeričkih analiza konstrukcije.
Abstract (english)
The theme of this master thesis is design and development of powered microlight hang glider and numerical analysis of its construction. The history of hang gliding, design of hang gliders and the techniques for flying are described in the introduction. After market research and analysis of existing products, the characteristics of microlight hang gliders are defined and solutions for particular design requirements are presented and analyzed. Based on this, the concept of a microlight hang glider was designed and modeled using SolidWorks. The concept is presented in detail and structure assembly as well as disassembly are described. The importance of the correct dimensioning of the structure pipes is described and the position of the pilot during the flight is shown using Catia V5. In the following, a numerical analysis of the construction was carried out using Abaqus. First, the stresses of the structure during flight were checked for multiple loading cases. Afterwards, the strength of the structure during landing when impact load occurs is analyzed. On the basis of the numerical analysis of the structural stress, it was concluded that individual pipes were over-dimensioned and, after changing the diameter and wall thickness of these pipes, another structural stress analysis was performed. The final chapter provides a conclusion based on the numerical analysis of the structure.
