GEMINI SOUTH WIND TEST DATA CODE ID = p00030oh

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 : open
  • Downwind gate: half open
FIGURE SUMMARY

(max wind = 20 m/s)

At +X: Resultant 2.8 m/s
U= .4 V= .6 W= .5
Resultant V_RMS = 1.5

At -X: Resultant 4.7 m/s
U= 1.9 V= 3.6 W= .5
Resultant V_RMS = 2.0

At -Y: Resultant 2.1 m/s
U= .6 V= -.8 W= -.4
Resultant V_RMS = 1.0

At M2: Resultant 5.7 m/s
U= .4 V= 5.0 W= 1.3
Resultant V_RMS = 1.6

At Dome: Resultant 11.3 m/s
U= -.5 V= 9.1 W= 6.3
Resultant V_RMS = 1.5
