GEMINI SOUTH WIND TEST DATA CODE ID = p18060oo

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

At +X: Resultant 2.4 m/s
U= -1.2 V= -.3 W= .5
Resultant V_RMS = 1.3

At -X: Resultant 1.9 m/s
U= -.4 V= -.6 W= .2
Resultant V_RMS = 1.0

At -Y: Resultant 1.4 m/s
U= -.2 V= .1 W= .5
Resultant V_RMS = .6

At M2: Resultant 2.9 m/s
U= .1 V= -1.3 W= .2
Resultant V_RMS = 1.6

At Dome: Resultant 7.9 m/s
U= 1.3 V= -5.7 W= 2.7
Resultant V_RMS = 3.5
