Abstract

UAV is an aircraft that flies without an operator in it and can fly autonomously by processing data. During a natural disaster, the needs of the refugees are urgently needed and to distribute it when a natural disaster occurs is quite difficult due to the terrain due to the natural disaster. Therefore, researchers designed a UAV that can vertical takeoff and landing (VTOL) to help distribute the needs of the refugees. The method used is analytical method and numerical method with reference from Raymer’s book. Where, the design process begins with determining DR&O, determining weight, wing span, wing geometry, fuselage and tail. The results of the geometry are drawn in 3 dimensions using CATIA software. Then the results of the 3-dimensional image were analyzed to determine the aerodynamic characteristics of the UAV aircraft using ANSYS software. The results of the UAV VTOL aircraft design show that the aircraft has a rectangular wing shape with a high wing position, double tailboom, conventional tail, an engine mounted on a pusher and 4 engines to perform vertical take off and landing on the wing. The results of aerodynamic analysis carried out on the design results of the UAV C21 (Cargo) with a speed of 33.3 m/s, at an angle of attack of 0o obtained CL of 0.38 and CLmax of 1.21 at an angle of 10o . The value of CD at 0 o angle of attack is 0.028 and CDmax is 0.15 at 16o angle.
