GEMINI SOUTH WIND TEST DATA CODE ID = q00030oc

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

  • Wind attack direction to SLIT = 000 degree Azimuth angle
  • Zenith angle = 30 degree (60 degree Elevation)
  • Upwind gate : open
  • Downwind gate: closed
FIGURE SUMMARY

(max wind = 20 m/s)

At +X: Resultant 1.4 m/s
U= -.5 V= -.9 W= .4
Resultant V_RMS = .6

At -X: Resultant 1.9 m/s
U= -.3 V= 1.2 W= -.3
Resultant V_RMS = 1.1

At -Y: Resultant .7 m/s
U= .0 V= -.1 W= -.1
Resultant V_RMS = .3

At M2: Resultant 4.2 m/s
U= -1.0 V= 3.4 W= 1.0
Resultant V_RMS = 1.3

At Dome: Resultant 8.8 m/s
U= -1.4 V= 7.1 W= 4.6
Resultant V_RMS = 1.5
