Overview

ViGYAN's Low Speed Wind Tunnel

 

Mars Phoenix Lander ViGYAN supported this NASA study to help in the analysis and prediction of the vehicle's entry aerodynamics. Similar studies have been conducted in support of NASA's Mars Science Laboratory, the Mars Exploration Rover, and earlier NASA Mars-entry studies.

 

GE Transportation ViGYAN has tested heat sensors for GE Transportation to better understand airflow and to help develop improved internal architectures. The sensors are typically installed on railroads to look for bearings that become hot as trains transverse the tracks.

 

Architectural Screens ViGYAN has conducted drag testing for Cambridge Architectural to measure drag on architectural screen materials to better assess wind loads on the materials incorporated into building designs.

 

Physical Description

ViGYAN's Low Speed Wind Tunnel is a conventional, straight-through, open-return layout powered by a variable-pitch, multi-blade axial fan located at the exit, providing a precisely controlled airspeed in the test section, ranging from 40 to 180 feet per second (27 to 122 miles per hour).
