COMPARISON OF SANDWICH COMPOSITE WING STRUCTURE WITH BALSA WOOD (CASE STUDY OF UAV AIRCRAFT FIXED WING VTOL VX-2)

UAV aircraft with a fixed wing configuration multi-rotor are capable of vertical take-off and landing (VTOL). In designing the structure aircraft, weight factor strength factors that need to be considered. The use sandwich composite materials on wings is expected able meet requirements namely having light weight, high rigidity strength. this study, comparative analysis balsa wood VTOL VX-2 was carried out. steps taken model sandwiches using CATIA. Performing process structural ANSYS software. Both half-span models subjected lift loads. From results, (glass fiber skin styrofoam core) stronger than under take off While rods, upper lower spars loads, but overall
