DEVELOPMENT OF VTOL UAV WITH MODULE FOR DIRECTION FINDING

This paper discusses the design, fabrication and flight test of a vertical take-off and landing aircraft equipped with a module capable of detecting the position of GPS disturbance signal (jamming signal)when such signal is detected. During the initial shape design, an estimation of the aircraft weight was first made based on the aircraft components and the bill of materials (BOM) of the aircraft. After reflecting the weight of all the components in the design, the shape design of the main wing was performed, followed by center of gravity and neutral point estimation, and propulsion system design. We have fabricated a UAV that can actually takeoff and land vertically and checked its flight performance through real flight tests. An aerodynamic analysis is performed using XFLR5. The E-107 and NACA0012 airfoils were selected as the airfoils for the main wing and tail wings, respectively, and it is designed as H-Tail type for good structural strength. The quad-copter is arranged such that the center of gravity (CG) of the quad-copter motors passes through the neutral point (NP) of the aircraft.
