GEMINI SOUTH WIND TEST DATA CODE ID = q04515oo

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 = 15 degree (75 degree Elevation)
  • Upwind gate : open
  • Downwind gate: open
FIGURE SUMMARY

(max wind = 20 m/s)

At +X: Resultant 5.4 m/s
U= 4.5 V= 1.3 W= .9
Resultant V_RMS = 2.3

At -X: Resultant 10.0 m/s
U= 7.3 V= 6.3 W= 2.2
Resultant V_RMS = 1.3

At -Y: Resultant 4.9 m/s
U= 4.2 V= 1.1 W= .7
Resultant V_RMS = 2.4

At M2: Resultant 2.4 m/s
U= .0 V= .1 W= .7
Resultant V_RMS = 1.2

At Dome: Resultant 13.8 m/s
U= 9.7 V= 5.4 W= 8.0
Resultant V_RMS = 1.2
