GEMINI SOUTH WIND TEST DATA CODE ID = c18060co

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

  • Wind attack direction to SLIT = 180 degree Azimuth angle
  • Zenith angle = 60 degree (30 degree Elevation)
  • Upwind gate : closed
  • Downwind gate: open

(max wind = 20 m/s)

At +X: Resultant 3.2 m/s
U= -1.6 V= -2.3 W= -.5
Resultant V_RMS = 1.5

At -X: Resultant 1.5 m/s
U= -.2 V= .9 W= .8
Resultant V_RMS = .6

At -Y: Resultant 1.5 m/s
U= .3 V= .0 W= .6
Resultant V_RMS = .6

At M2: Resultant 3.6 m/s
U= -2.0 V= -1.6 W= -.6
Resultant V_RMS = 1.8

At Dome: Resultant 4.0 m/s
U= -.1 V= -2.2 W= 1.2
Resultant V_RMS = 2.0
