GEMINI SOUTH WIND TEST DATA CODE ID = q04560oc

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

(max wind = 20 m/s)

At +X: Resultant 5.9 m/s
U= 5.4 V= -1.4 W= 1.1
Resultant V_RMS = 1.3

At -X: Resultant 7.2 m/s
U= 5.3 V= 4.3 W= 2.0
Resultant V_RMS = 1.7

At -Y: Resultant 3.6 m/s
U= 2.9 V= -1.3 W= -.1
Resultant V_RMS = 1.2

At M2: Resultant 2.3 m/s
U= -1.0 V= -.3 W= 1.0
Resultant V_RMS = 1.1

At Dome: Resultant 34.0 m/s
U=-19.7 V= 19.6 W=-19.7
Resultant V_RMS = .6
