GEMINI SOUTH WIND TEST DATA CODE ID = q09045oo

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 = 45 degree (45 degree Elevation)
  • Upwind gate : open
  • Downwind gate: open
FIGURE SUMMARY

(max wind = 20 m/s)

At +X: Resultant 4.3 m/s
U= 4.0 V= .1 W= .6
Resultant V_RMS = 1.6

At -X: Resultant 7.6 m/s
U= 7.2 V= -.7 W= 1.6
Resultant V_RMS = 1.8

At -Y: Resultant 5.5 m/s
U= 5.4 V= -.2 W= -.2
Resultant V_RMS = 1.6

At M2: Resultant 1.3 m/s
U= .5 V= -.2 W= .2
Resultant V_RMS = .7

At Dome: Resultant 12.1 m/s
U= 10.0 V= -1.3 W= 6.5
Resultant V_RMS = 1.4
