GEMINI SOUTH WIND TEST DATA CODE ID = q09060co

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

  • Wind attack direction to SLIT = 090 degree Azimuth angle
  • Zenith angle = 60 degree (30 degree Elevation)
  • Upwind gate : closed
  • Downwind gate: open

At +X: Resultant 1.0 m/s
U= -.4 V= -.4 W= .0
Resultant V_RMS = .6

At -X: Resultant .7 m/s
U= .2 V= .1 W= -.3
Resultant V_RMS = .3

At -Y: Resultant .9 m/s
U= .7 V= .0 W= .1
Resultant V_RMS = .4

At M2: Resultant 1.0 m/s
U= -.3 V= -.7 W= .3
Resultant V_RMS = .5

At Dome: Resultant 14.2 m/s
U= 10.6 V= -3.9 W= 8.4
Resultant V_RMS = 1.4
