VST studies identify and quantify spin and spin-recovery characteristics of a given vehicle configuration. Related tumbling research identifies susceptibility to out-of-control pitch auto rotation and strategies for safe recovery.
Maneuvering aircraft may encounter a dangerous condition known as spin, caused by a sudden loss of lift over wings or control surfaces. NASA’s 20-Foot Vertical Spin Tunnel (VST) is the only operational tunnel of its kind in the Western Hemisphere that conducts free-spin research using dynamically scaled, free-flying models. The VST is a closed-throat, annular-return facility that operates at nominal atmospheric conditions, with velocities that can be rapidly adjustable up to 85 ft per sec.
Developing quieter, more efficient engines for next generation aircraft takes a lot of testing. Here in our 9×15 wind tunnel, research mechanics made final preparations for the Advanced Ducted Propulsor Fan Commissioning test, which could help improve the performance of engines for passenger aircraft.
AETC Ground Facilities
AETC sets the strategic direction for NASA’s versatile and comprehensive portfolio of ground test aeronautics research capabilities.
Among these assets are subsonic, transonic, supersonic, and hypersonic wind tunnels and propulsion test facilities at Ames Research Center, Glenn Research Center, and Langley Research Center.
