Computational Fluid Dynamics (CFD) Analysis of Aerodynamics Characteristics of UAV in Aircraft

Abstract

- In this research explores the aerodynamics behaviour of a simple UAV (Unmanned Aerial Vehicle) concept and analysis. Analytical research, i.e. Steady-state, three-dimensional Computational fluid dynamics (CFD) on the Tactical Unmanned Air Vehicle (TUAV) Ranger with mach 0.1 and 0.19 was calculated and compared with each Mach number using this method of analysis. Pressure contours and speed contours are shown, and from a reasonable view, all drawn by an ANSYS ICEM CFD study, the Turbulence region is expected. Without an onboard pilot utilising the digital and electronic system manned aircraft do not have, UAV has its own benefits, such as computerizing and autonomous. There is also no chance of life loss and servicing is better than manned planes. To evaluate the aircraft wing model's aerodynamic characteristics, both bird and wing. In contrast to other winglet types, the winglet has the highest cant angles of 45 ° (CL = 8.9774).
