DATA ACQUISITION FOR VEHICLES IN CONFINED SPACES (VICS-70) FACILITY

Tests were conducted at the VICs-70 facility using scale models under a variety of simulated conditions. Model test data reduction procedures for steady-state tube vehicle aerodynamics are described. Sample calculations of equilibrium velocity, drag coefficients, tube pressure gradient, tube flow velocity ratio, effective tube length and effective friction factor in proximity to the model are included. Results of the test program are presented with reference to: velocity history; effects of model nose and tail perturbations on drag; drag as a function of blockage ratio, vehicle length, tunnel length, Reynolds number, and vehicle roughness, drag coefficient sensitivity to blockage ratio; and tube length and tube flow velocity ratio as a function of blockage ratio, vehicle length and test section length.
