Characteristics
(VST) is the only operational tunnel of its kind in the Western Hemisphere that conducts free-spin research using dynamically scaled, free-flying mode ls.
Facility Benefits
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.
Facility Applications
It is the only resource available to commercial aircraft manufacturers for proprietary spin-and-tumble assessments of their products in a wind tunnel environment.
Data Acquisition
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.

Fact Sheet
20-Foot Vertical Spin Tunnel
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.
