GEMINI SOUTH WIND TEST DATA CODE ID = q04530oo

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

(max wind = 20 m/s)

At +X: Resultant 6.8 m/s
U= 6.3 V= .8 W= 1.5
Resultant V_RMS = 2.3

At -X: Resultant 9.8 m/s
U= 7.3 V= 5.8 W= 2.4
Resultant V_RMS = 1.5

At -Y: Resultant 4.9 m/s
U= 4.2 V= .9 W= .5
Resultant V_RMS = 2.4

At M2: Resultant 2.7 m/s
U= .3 V= -.4 W= 1.0
Resultant V_RMS = 1.3

At Dome: Resultant 34.0 m/s
U=-19.6 V= 19.6 W=-19.6
Resultant V_RMS = .6
