GEMINI SOUTH WIND TEST DATA CODE ID = q13515oo

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

  • Wind attack direction to SLIT = 135 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 1.6 m/s
U= .0 V= .2 W= .1
Resultant V_RMS = .9

At -X: Resultant 7.3 m/s
U= 4.1 V= -5.4 W= 2.4
Resultant V_RMS = 1.3

At -Y: Resultant 1.7 m/s
U= -.2 V= 1.2 W= .4
Resultant V_RMS = .7

At M2: Resultant 5.4 m/s
U= 1.9 V= -2.7 W= 3.9
Resultant V_RMS = 2.1

At Dome: Resultant 13.0 m/s
U= 8.2 V= -8.1 W= 5.4
Resultant V_RMS = 2.1
