Abstract

High-speed ground tracking radar systems rotating at about 60 rpm are currently being implemented as modern air traffic control systems in airports. The flow induced vibration and noise generation of the newly developed radar antennas are the two serious problems that jeopardise the successful deployment of the new ground-based aircraft tracking systems. This paper deals with the viscous flow details of the highly three-dimensional antenna tip section and the vortex shedding characteristics at Re = 426,000. The current analysis uses a 3D computational approach for the computation of viscous flow details around a highly 3D tip geometry. A 2D unsteady computation of the vortex shedding phenomena is also presented. This paper is a continuation of the computational study dealing with the determination of aerodynamic drag coefficients on advanced surface detection equipment (ASDE-X) antenna previously presented in Gumusel and Camci (2010).
