Abstract

Surveillance UAV (Unmanned Aerial Vehicle) is generally used to monitor area for various purposes. Weight and balance are used to determine the location of CG and the stability. This research determines wing loading, power weight ratio as well as to determine the wing area and motor power needed to analytically support the UAV using a brushless motor, configure the flying wing with relative speed of air from 12 m/s to 24 m/s. Weight and balance calculation in this research was to find the mass value and center mass of the UAV airframe by entering the properties of several materials in the form of density on the airframe components using CATIA software. The material is EPP Foam reinforced with carbon tube. The results of airframe mass analysis using CATIA was combined with other UAV components to obtain the total mass and center of mass of the UAV. The results were the total mass of 2144 grams, the wing area of 0,608 m2 with a span of 1,6 meters, the power requirement of 231,9 Watts, and the overall CG location of the vehicle was located at the X coordinate of 75,66 mm from the datum, at the Y coordinate of 1,15 mm from the datum and at the Z coordinate of 3,89 mm from the datum. The location of CG was 117,34 mm or 60% MAC in front of the neutral point and flight endurance 0,651 hours behind the leading-edge chord root.
