This master's thesis, developed in cooperation with Rhythm Automotive Czech a.s., addresses the structural design and stress analysis of a modular fixed-wing unmanned aerial vehicle (UAV) airframe. The design is based on the existing VUT 700 SPECTO aircraft, whose aerodynamic surfaces were fully retained. The primary objective was to transform the airframe into a robust, modular system enabling rapid assembly in field conditions without specialized tooling. The modifications include alternative designs for the wing and tail boom mechanical interfaces, a detachable payload nose, and a catapult launch interface. Since the original wing was adopted without modifications, the structural analysis focused specifically on the newly designed fuselage and its critical load-bearing joints. Analytical evaluations demonstrated that the proposed fuselage complies with the structural airworthiness requirements of the NATO AEP-83 military standard, yielding positive reserve factors. The outcomes of this thesis provide a substantiated foundation for the detailed design phase and subsequent prototype manufacturing.

Študent prezentoval výsledky svojej diplomovej práce komisii. Nasledovala otázka oponenta. Otázka oponenta bola zameraná na spojovací mechanizmus vhodný pre finalnu implementáciu spojov pre hlavné konštrukčné celky. Študent odpovedal na otázku oponenta samostatne ku spokojnosti komisie. Prvá otázka komisie k práci bola na multikriteriálne hodnotenie navrhnutých spojovacích mechanizmov. Študent odpovedal na otázku samostatne ku spokojnosti komisie. Druhá otázka komisie k práci bola dôvod utajenia práce. Študent odpovedal na otázku samostatne ku spokojnosti komisie. Tretia otázka komisie k práci bola akým spôsobom boli počítané priebehy zaťaženia a ako by mali tieto pribehy vyzerať. Študent odpovedal na otázku samostatne ku spokojnosti komisie. Štvrtá otázka komisie k práci bola zameraná na vysvetlenie obrázku v prezentácii týkajúceho sa spojenia krídlo chvost. Študent odpovedal na otázku samostatne ku spokojnosti komisie. Piata otázka komisie k práci bola o indikácii zaistenia na prinesenom modeli. Študent odpovedal na otázku samostatne ku spokojnosti komisie. Ďalšia otázka komisie k práci bola o problemoch komerčne dostupných kontaineroch a o vhodnosti nadstavby na vozidlo Toyota Hilux. Študent odpovedal na otázku samostatne ku spokojnosti komisie. Následne sa prešlo na všeobecnú rozpravu.
