Abstract
The first series of tests to obtain aerodynamic characteristics of a model fired in the renovated DREV Aeroballistic Range is described. All the instrumentation and software were tested for the first time. The model consisted of a nose cone on a cylindrical body with four rectangular fins. Thirteen models with different surface roughnesses were fired in the Mach number range from 1.7 to 2.5. The test results showing the effect of surface roughness on the drag coefficient are presented.
