GEMINI SOUTH WIND TEST DATA CODE ID = c18060oo

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

  • Wind attack direction to SLIT = 180 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 2.5 m/s
U= -1.0 V= -1.8 W= -.2
Resultant V_RMS = 1.5

At -X: Resultant 1.4 m/s
U= .0 V= .7 W= .2
Resultant V_RMS = .5

At -Y: Resultant 1.2 m/s
U= .3 V= .3 W= .3
Resultant V_RMS = .6

At M2: Resultant 3.0 m/s
U= -1.5 V= -1.6 W= -.5
Resultant V_RMS = 1.6

At Dome: Resultant 3.0 m/s
U= .5 V= -.8 W= 1.2
Resultant V_RMS = 1.7
