GEMINI SOUTH WIND TEST DATA CODE ID = q09045oc

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

  • Wind attack direction to SLIT = 090 degree Azimuth angle
  • Zenith angle = 45 degree (45 degree Elevation)
  • Upwind gate : open
  • Downwind gate: closed
FIGURE SUMMARY

AVERAGE Wind speeds
(max wind = 20 m/s)

At +X: Resultant 1.9 m/s
U= -.2 V= -.6 W= .1
Resultant V_RMS = .8

At -X: Resultant 4.1 m/s
U= 3.7 V= .1 W= 1.0
Resultant V_RMS = 1.5

At -Y: Resultant 2.0 m/s
U= -1.4 V= .2 W= .8
Resultant V_RMS = .8

At M2: Resultant 3.8 m/s
U= 1.6 V= -1.4 W= 2.8
Resultant V_RMS = 1.4

At Dome: Resultant 10.5 m/s
U= 8.6 V= -.9 W= 5.7
Resultant V_RMS = 1.3
