GEMINI SOUTH WIND TEST DATA CODE ID = q04560oo

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

  • Wind attack direction to SLIT = 045 degree Azimuth angle
  • Zenith angle = 60 degree (30 degree Elevation)
  • Upwind gate : open
  • Downwind gate: open
FIGURE SUMMARY

(max wind = 20 m/s)

At +X: Resultant 8.5 m/s
U= 8.2 V= -1.0 W= .9
Resultant V_RMS = 1.5

At -X: Resultant 9.2 m/s
U= 7.2 V= 5.1 W= 2.2
Resultant V_RMS = 1.8

At -Y: Resultant 5.5 m/s
U= 4.7 V= .5 W= -2.1
Resultant V_RMS = 1.9

At M2: Resultant 2.1 m/s
U= -.6 V= -.1 W= -.2
Resultant V_RMS = 1.2

At Dome: Resultant 15.0 m/s
U= 10.9 V= 5.9 W= 8.3
Resultant V_RMS = 1.3
