EXPERIMENTAL INVESTIGATION OF THE NEAR FLOW FIELD FOR TUBE VEHICLES

The experimental results from an investigation of the near flow field for tube-vehicle systems are reported. The data were obtained from a tube-vehicle test facility which is 200 feet long and instrumented to measure vehicle drag, history of static wall pressure and dynamic pressure. Emphasis is on the accurate measurement of the dynamic pressure to determine the flow velocity in front of the vehicle. With this data and drag force, a drag coefficient is defined and related to the relative Mach number and the ratio of relative flow velocity to vehicle velocity. The experimental results are correlated with an analysis of the near flow field and results from other studies. (Author)
