Introductory Description:
An exciting career opportunity exists for an experienced Linux System Administrator as a key member of a small team of engineers and technicians who operate and maintain the Air Force’s and Department of Defense’s primary high Mach number and high Reynolds number facility for hypersonic ground testing and the validation of computational simulations.
This opportunity is being offered by National Aerospace Solutions, LLC at the Hypervelocity Wind Tunnel No. 9 (Tunnel 9) located at the Silver Spring, MD site of AEDC. Tunnel 9 is a Geographically Separated Unit (GSU) of a larger organization and as a result many discrete functions are small in scale and accomplished with a smaller, more agile workforce than that of a large organization. Tunnel 9 provides aerodynamic simulation critical to hypersonic system development and hypersonic vehicle technologies at speeds from Mach 7 to Mach 18. Tunnel 9 is the highest Reynolds number, largest scale ground test facility in the world capable of simultaneously collecting continuous pitch polar static force and moment, pressure and heat transfer data during each run.
AEDC is the nation’s largest aerospace ground test facility complex that includes 58 aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, space environmental chambers, arc heaters, ballistic ranges and other specialized test units. Twenty-seven of the test units have capabilities unmatched in the United States and 14 have capabilities unmatched in the world. Using its ground test facilities, AEDC supports propulsion, aerodynamic, reentry, trans-atmospheric and spaceflight systems testing.
