GEMINI SOUTH WIND TEST DATA CODE ID = d09060oo

Average and RMS wind pressures and average wind velocities were calculated from the wind test in the following conditions:

  • Wind attack direction to SLIT = 090 degree Azimuth angle
  • Zenith angle = 60 degree (30 degree Elevation)
  • Upwind gate : open
  • Downwind gate: open

At +X: Resultant 10.0 m/s
U= -9.8 V= .2 W= 1.9
Resultant V_RMS = .6

At -X: Resultant 8.5 m/s
U= -8.3 V= .5 W= .5
Resultant V_RMS = 1.3

At -Y: Resultant 5.0 m/s
U= -4.8 V= -.3 W= -.2
Resultant V_RMS = 1.3

At M2: Resultant 1.9 m/s
U= .6 V= .1 W= -.6
Resultant V_RMS = 1.0

At Dome: Resultant 4.1 m/s
U= 1.2 V= -1.6 W= 1.1
Resultant V_RMS = 1.6
