GEMINI SOUTH WIND TEST DATA CODE ID = d09060oh

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 = 60 degree (30 degree Elevation)
  • Upwind gate : open
  • Downwind gate: half open
FIGURE SUMMARY

AVERAGE Wind speeds
(max wind = 20 m/s)

At +X: Resultant 9.9 m/s
U= -9.7 V= .4 W= 1.6
Resultant V_RMS = .7

At -X: Resultant 8.2 m/s
U= -8.0 V= .5 W= .3
Resultant V_RMS = 1.4

At -Y: Resultant 4.7 m/s
U= -4.3 V= .8 W= -.7
Resultant V_RMS = 1.6

At M2: Resultant 1.7 m/s
U= .9 V= .3 W= -.8
Resultant V_RMS = .9

At Dome: Resultant 3.6 m/s
U= 2.5 V= -1.8 W= 1.1
Resultant V_RMS = 1.0
