GEMINI SOUTH WIND TEST DATA CODE ID = q09045oh

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: half open
FIGURE SUMMARY

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

At +X: Resultant 3.2 m/s
U= 2.5 V= -.2 W= .6
Resultant V_RMS = 1.4

At -X: Resultant 7.7 m/s
U= 7.3 V= -.9 W= 1.7
Resultant V_RMS = 1.7

At -Y: Resultant 4.1 m/s
U= 3.7 V= -.1 W= .4
Resultant V_RMS = 1.8

At M2: Resultant 2.1 m/s
U= .7 V= -.6 W= .6
Resultant V_RMS = 1.1

At Dome: Resultant 12.6 m/s
U= 10.5 V= -1.3 W= 6.7
Resultant V_RMS = 1.4
