Abstract

The aim of this paper is to determine and study the aerodynamics characteristics of an Agricultural Spraying Unmanned Air Vehicle (ASUAV) that designed in the Faculty of Engineering-Omdurman Islamic University. Since flight testing can be expensive and dangerous, other methods are required to simulate flight test conditions for low subsonic vehicle system. In this research, Computational Fluids Dynamics (CFD) was used to simulate the flight test and determine the aerodynamic characteristics such as lift and drag coefficients at various angles of attack. The quality of flow pattern around the ASUAV was clearly observed. Generally, the current approach shows that the proposed configuration has suitable aerodynamic characteristics. The promising results of this study opened the door for developing and manufacturing the ASUAV which have been successfully flight in June 2012.
