GEMINI SOUTH WIND TEST DATA CODE ID = c13560co

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

At +X: Resultant 5.9 m/s
U= -3.2 V= -4.5 W= -.8
Resultant V_RMS = 2.3

At -X: Resultant 2.2 m/s
U= 1.9 V= -.3 W= -.5
Resultant V_RMS = .6

At -Y: Resultant 1.4 m/s
U= -.2 V= -.4 W= -1.1
Resultant V_RMS = .5

At M2: Resultant 7.8 m/s
U= -5.0 V= -5.5 W= 1.4
Resultant V_RMS = 1.3

At Dome: Resultant 2.9 m/s
U= .9 V= .2 W= 1.6
