Tunnel 9 contains two test legs to accommodate the multiple testing capabilities available at the facility. Each leg contains a test cell which is five feet in diameter and over twelve feet in length. These test cells can accommodate full-scale reentry bodies, full-scale endo-interceptors, and large-scale aerospace vehicles and hypersonic inlet models.
With nominal test times up to 15 seconds, Tunnel 9 provides high test productivity by allowing parametric variations (such as angle-of-attack sweeps, control jet operations, window cooling operations, and/or flow surveys) on heavily instrumented models during a single run.
The combination of constant test conditions, long test times, and large test cells at Tunnel 9 provides a meaningful, productive, and cost-effective test environment for aerodynamic, aerothermal, aerostructural, aero-optic, shroud removal, and hypersonic inlet experiments unavailable anywhere else.
