GEMINI SOUTH WIND TEST DATA CODE ID = c18030co

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

At +X: Resultant 7.1 m/s
U= -3.7 V= -5.8 W= .7
Resultant V_RMS = 1.6

At -X: Resultant 1.1 m/s
U= -.6 V= .3 W= .2
Resultant V_RMS = .5

At -Y: Resultant 1.5 m/s
U= -.6 V= .4 W= .7
Resultant V_RMS = .7

At M2: Resultant 3.8 m/s
U= -2.0 V= -2.7 W= .5
Resultant V_RMS = 1.6

At Dome: Resultant 3.7 m/s
U= -.3 V= -1.8 W= 1.1
Resultant V_RMS = 1.9
