Tunnel 9 receives a much needed refresh
These three driver large vessels can be pressurized to 40,000 pounds per square inch and are one of the enabling technologies that make Hypervelocity Wind Tunnel 9 unique. During major maintenance they are rolled outside of the tunnel building into a maintenance bay. The gray steel fixture, pictured, is used to extract the central plug out of each driver vessel.
