With three suction type wind blowers, it can simulate wind speed from m/s all the way up to 11 m/s. For more information on wind tunnel . The High Speed Wind Tunnel is a blowdown-to-atmosphere, transonic-supersonic, adjustable-Mach-number facility. The general arrangement of the facility is shown in an aerial photograph in Figure A schematic drawing indicating wind tunnel circuit layout is provided as Figure Figure High Speed Wind Tunnel General Arrangement.
Wind Tunnel Operations Division Test Planning Guide for High Speed Wind Tunnels AXB2 Revision 5 Ap This is a controlled document. The ramjet engine is mounted to the exit nozzle of the Supersonic Wind Tunnel (SSWT). The duct area dimensions of the ramjet engine are inches wide by inches high to match the exit nozzle of the Super Sonic Wind Tunnel. The overall length of the ramjet engine is six feet long. The length is broken into three equal. Low and high speed calibrations are available, as well as wind direction. Low Speed Test. Calibrations are performed in the range to 15 m/s. Our measurement uncertainty is ± m/s or ±1% (whichever is greater) at a 95% confidence level with a K coverage factor of 2 unless otherwise stated. High Speed Test.
design variables of unsuppressed coannular plug nozzles through a systematic static acoustic and wind tunnel aerodynamic performance measurements. The variables considered were radius ratio, area ratio, inner stream plug geometry, inner and outer stream flow variables, and inner to outer stream velocity and weight-flow ratios.

At the lower left is the NASA Ames 80 x , which is a full scale, low speed wind tunnel. Working Fluid. Wind tunnels can be designated by the type of fluid that is used in the tunnel. For most low speed aircraft wind tunnel testing, air is moved through the tunnel.

We want the highest possible velocity in the test section of the wind tunnel. For a supersonic wind tunnel, we contract the flow until it chokes in the throat of a nozzle.
We then diffuse the flow which increases the.The full wind tunnel test evaluates the effectiveness of the candidate sampler at 2 ebook and 24 km/hr for ebook of the size specified in table F-2 of this subpart (under the heading, “Full Wind Tunnel Test”).
For each wind speed, a smooth curve is fit to the effectiveness data and corrected for the presence of multiplets in the wind.
