GEMINI SOUTH WIND TEST DATA CODE ID = c18030cc

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: closed

At +X: Resultant .5 m/s
U= -.3 V= -.3 W= -.1
Resultant V_RMS = .3

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

At -Y: Resultant .5 m/s
U= -.2 V= -.1 W= -.1
Resultant V_RMS = .3

At M2: Resultant 1.5 m/s
U= .2 V= .4 W= .4
Resultant V_RMS = .8

At Dome: Resultant 4.3 m/s
U= .1 V= -2.2 W= 1.2
Resultant V_RMS = 2.3
