GEMINI SOUTH WIND TEST DATA CODE ID = c13560cc

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: closed

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

At -X: Resultant .6 m/s
U= -.4 V= .1 W= -.4
Resultant V_RMS = .2

At -Y: Resultant .4 m/s
U= -.2 V= -.1 W= -.2
Resultant V_RMS = .2

At M2: Resultant .8 m/s
U= .4 V= .0 W= -.3
Resultant V_RMS = .5

At Dome: Resultant 3.7 m/s
U= 2.7 V= .2 W= 2.1
Resultant V_RMS = 1.0
