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.
