Abstract

Unmanned Aerial Vehicle (UAV) is an unmanned vehicle aircraft that can carry out various missions including military and civilian (general) missions. In its military mission, UAV aircraft are operated to spy on enemy areas and enemy conditions, and in civilian missions, UAVs are used for agriculture, plantations and search for disaster victims. As for the purpose of this study to determine the flow of weight and balance, center of gravity calculation and comparison between center of gravity results from CATIA software with weight and balance UAV Sky King. The UAV Sky King is a type of aircracft that used a fixed wing with the character of the slow flyer, weight and balance of the aircraft can be determined by determining the center of gravity (CG). Center of gravity (CG) must be maintained so that the aircraft can balance both the lateral and longitudinal axes. In calculating the center of gravity (CG), the Sky King UAV plane is determined by the weight, arm, and moment of each component of the aircraft, and to get the data can be done by observation, literature studies, and interviews. After doing the calculation of weight and balance, the center of gravity will be calculated on three conditioned, by CATIA (without servo), direct calculation (without servo), and direct calculation (with servo). The center of gravity from CATIA (without servo) at X coordinate is -484,888269 mm, at Y coordinate is 0 mm, at Z coordinate is -27,735797 mm. The center of gravity at direct calculation (without servo) at X coordinate is -424,390909 mm, at Y coordinate is 0 mm, at Z coordinate is 10,326299 mm. The center of gravity from direct calculation (with servo) at X coordinate is -432,131777 mm, at Y coordinate is 0 mm, at Z coordinate is 11,472941mm. Also the error percentage from CATIA calculation and direct calculation on UAV without servo is 0,124766% at X coordinate, 0 % at Y, coordinate 1,372309% at Z coordinate.
