GEMINI SOUTH WIND TEST DATA CODE ID = c13530co

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

  • Wind attack direction to SLIT = 135 degree Azimuth angle
  • Zenith angle = 30 degree (60 degree Elevation)
  • Upwind gate : closed
  • Downwind gate: open

At +X: Resultant 8.8 m/s
U= -5.6 V= -6.4 W= 1.5
Resultant V_RMS = 1.8

At -X: Resultant 2.0 m/s
U= 1.4 V= .1 W= .4
Resultant V_RMS = .9

At -Y: Resultant 1.7 m/s
U= -.3 V= 1.0 W= -.2
Resultant V_RMS = .6

At M2: Resultant 10.9 m/s
U= -7.2 V= -6.4 W= 4.9
Resultant V_RMS = 1.2

At Dome: Resultant 2.8 m/s
U= 1.2 V= .4 W= 1.5
Resultant V_RMS = 1.1
