Wing design of uav serindit v-1

Abstract

Abstract UAVs are controlled aircraft without the presence of pilots in them. In its use, UAVs have been used for both military and civilian purposes. In the field of plantations, UAVs are used for mapping and monitoring (survey) of an area such as areas of industrial plantations, oil palm plantations and areas of forest fire disaster in a timely and precise manner. To develop a UAV capable of carrying out the mission of mapping the coastal estate’s area, in this research is done wing design UAV which is named serindit V-1. The design process begins with the design concept, then proceed with a preliminary design that aims to determine the dimensions and initial configuration of the wing UAV serindit V-1. Furthermore, the wing UAV serindit V-1 is simulated on XFLR5 software using Clark’s airfoil, GOE 611 and S7055. Simulations were performed to see the characteristics of aerodynamic at takeoff speed (12 m / s), cruising speed (20 m / s) and maximum speed (30 m / s). Simulation result at the take-off speed and cruising speed show the lift coefficients produced by the three airfoils meet the requirements. Then, the highest value of the lift coefficient ratio to the air drag coefficient at cruising speed, produced by airfoil S7055 at a 3-degree angle of attack. Furthermore, the graph of the pitching moment coefficient on all angles of attack produced by the three airfoils shows a negative gradient. This shows the condition of wing stability in the pitching direction.
