GEMINI SOUTH WIND TEST DATA CODE ID = q04545ho

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 : half open
  • Downwind gate: open
FIGURE SUMMARY

(max wind = 20 m/s)

At +X: Resultant 4.7 m/s
U= 4.4 V= -.2 W= .8
Resultant V_RMS = 1.6

At -X: Resultant 6.7 m/s
U= 4.9 V= 4.2 W= 1.4
Resultant V_RMS = 1.3

At -Y: Resultant 2.8 m/s
U= 2.2 V= -.2 W= -.8
Resultant V_RMS = 1.4

At M2: Resultant 1.8 m/s
U= -.7 V= .1 W= .3
Resultant V_RMS = .9

At Dome: Resultant 11.7 m/s
U= 6.8 V= 3.4 W= 6.8
Resultant V_RMS = 3.5
