GEMINI SOUTH WIND TEST DATA CODE ID = d00060oo

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

  • Wind attack direction to SLIT = 000 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 2.6 m/s
U= .1 V= .0 W= -1.0
Resultant V_RMS = 1.0

At -X: Resultant 5.5 m/s
U= 3.6 V= 3.8 W= .3
Resultant V_RMS = 1.5

At -Y: Resultant 2.4 m/s
U= 1.9 V= -.8 W= .0
Resultant V_RMS = 1.0

At M2: Resultant 6.5 m/s
U= 3.7 V= 4.9 W= -.7
Resultant V_RMS = 2.7

At Dome: Resultant 11.2 m/s
U= 3.1 V= 9.1 W= 5.7
Resultant V_RMS = .3
