GEMINI SOUTH WIND TEST DATA CODE ID = q04545oo

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

  • Wind attack direction to SLIT = 045 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 6.5 m/s
U= 6.2 V= -.3 W= 1.0
Resultant V_RMS = 1.5

At -X: Resultant 9.1 m/s
U= 6.5 V= 5.9 W= 2.1
Resultant V_RMS = 1.2

At -Y: Resultant 3.1 m/s
U= 2.5 V= .0 W= -.1
Resultant V_RMS = 1.5

At M2: Resultant 3.2 m/s
U= -1.7 V= .4 W= -.6
Resultant V_RMS = 1.6

At Dome: Resultant 13.0 m/s
U= 9.1 V= 5.3 W= 7.5
Resultant V_RMS = 1.1
