GEMINI SOUTH WIND TEST DATA CODE ID = c13530oc

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 : open
  • Downwind gate: closed

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

At -X: Resultant 1.3 m/s
U= .5 V= .9 W= -.2
Resultant V_RMS = .6

At -Y: Resultant .9 m/s
U= .4 V= -.2 W= .0
Resultant V_RMS = .4

At M2: Resultant .9 m/s
U= .2 V= -.1 W= -.4
Resultant V_RMS = .4

At Dome: Resultant 3.5 m/s
U= 2.7 V= .7 W= 1.6
Resultant V_RMS = 1.1
