Abstract

Abstract This research paper conducts a study of aerodynamic drag coefficient of a sounding rocket named Rohini300 MK-II. There are various factor which plays important role in rocket stability and aerodynamic drag coefficient is one of them. Zero-lift drag coefficient, CD (i.e. drag coefficient at attack angle of zero degree) is evaluated and its behavior is observed with the different mach numbers. This paper defines the development of a CFD model of the RH 300 MK-II in the modeling software, then importing the 3D model into CFD software and then the creation of CFD domain, meshing of the domain of CFD, application of various boundary conditions and then obtaining plots and results for coefficient of drag. And Finally Result is cocluded to get its Zero Drag coefficient.
