NOL Mach 18 Hypervelocity Research Tunnel.
Abstract
The aerodynamic capabilities and physical characteristics of the Naval Ordnance Laboratory's Mach number 18 Hypervelocity Research Tunnel are described. This tunnel is a high-pressure, blowdown-type facility that uses nitrogen as the working gas. The facility provides a maximum test section Reynolds number of 0.2 million per meter (0.7 million per foot) at the maximum stagnation pressure of 700 atmospheres and a supply temperature of 2100 Kelvin. A forced-convection electric heater with a graphite heater element is used to achieve the required flow temperatures. The axisymmetric, contoured nozzle is 3.96 meters long with an exit diameter of 0.61 meters. Flow times are from one to four minutes.
