Tunnel Specifications

•  Circular cross section
•  6:1 inlet contraction ratio
•  closed test section (10’ diameter by 10’ long)
•  14’ diameter – 6 bladed fan
•  double C-sector model support ( alpha and beta sectors)
•  multiple model-sting arrangements (rear, top, or bottom model supports)
  
  

Test Capabilities

•  Vmax = 120 feet/sec
•  a = ±90∞ (±180∞ capability using alternate sting arrangements)
•  b = ±30∞ (±90∞ capability using alternate sting arrangements)
•  Static
•  Dynamic
  •  Steady-state rotation rate: ±150 RPMmax (about wind axis)
  •  Oscillatory: ±6 rad/sec max rate; ±180∞ max amplitude for roll and yaw and ±20∞ for pitch (about the body axis) [maximum amplitude and rate cannot be obtained at the same time]
  •  Combined motion (oscillatory about body axis while rotating about wind axis)

Test Measurements

•  6-component strain gauge balance (various load capabilities)
•  Surface pressures (PSI equipment)
•  Control hinge moments
•  Powered model (power measurements isolated from vehicle measurements)

Time History Recordings

•  In all test environments
•  For all test measurements
