- Optimization of the wing-fuselage interface of the UAS30-P2Publication . Deenadayalan, Tholkappiyan; Silva, Francisco José Gomes daThis thesis presents the optimization of the spar connector of the aircraft UAS30-P2. The spar connector is the primary airframe structure of the aircraft. It connects the all flight surfaces of the aircraft with the fuselage. The structure is made up of extruded aluminium bars. The spar connector supports all aerodynamic loads and inertial loads of the aircraft. These loads are transmitted through the carbon fibre reinforced polymer (CFRP) spar of the aircraft. Since the spar connector supports all the aerodynamic and inertial loads of the aircraft, it is the most crucial component in the entire Unmanned aerial vehicle (UAV). Thus, it needs to be strong and stiff enough to withstand the exceptional circumstances in which the aircraft must operate. The thesis reviews both, the choice of materials and shape optimization of the spar connector, achieving a more efficient structure. The choice of material is reviewed by studies conducted on the available materials for this purpose. The optimization is carried out using the studies and the results of the Finite element analysis (FEA) of the component. Later the optimized Finite element (FE) model of wing interface structure is analyzed based on the Finite element method results. The results were then compared with the analysis results of the original FE model of wing interface structure of UAS30-P2. As a result, it was observed an appreciable reduction accompanied by the improvement in the performance characteristics is of the metallic spar connector of UAS30-P2.
