GEMINI SOUTH WIND TEST DATA CODE ID = q00030co

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

(max wind = 20 m/s)

At +X: Resultant 2.0 m/s
U= -.3 V= 1.3 W= .3
Resultant V_RMS = 1.3

At -X: Resultant 1.1 m/s
U= -.3 V= -.7 W= -.2
Resultant V_RMS = .4

At -Y: Resultant .9 m/s
U= .3 V= -.4 W= -.3
Resultant V_RMS = .4

At M2: Resultant 4.3 m/s
U= .4 V= 3.5 W= 1.4
Resultant V_RMS = 1.3

At Dome: Resultant 9.3 m/s
U= 1.2 V= 7.1 W= 5.4
Resultant V_RMS = 1.5
