GEMINI SOUTH WIND TEST DATA CODE ID = p00060co

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

  • Wind attack direction to SLIT = 000 degree Azimuth angle
  • Zenith angle = 60 degree (30 degree Elevation)
  • Upwind gate : closed
  • Downwind gate: open

At +X: Resultant 2.7 m/s
U= -.7 V= 1.5 W= .3
Resultant V_RMS = 1.8

At -X: Resultant 1.3 m/s
U= -.4 V= -.5 W= -.1
Resultant V_RMS = .7

At -Y: Resultant 1.3 m/s
U= -.5 V= .0 W= -.7
Resultant V_RMS = .7

At M2: Resultant 3.0 m/s
U= 1.5 V= .2 W= 1.3
Resultant V_RMS = 2.1

At Dome: Resultant 14.4 m/s
U= -1.9 V= 12.2 W= 6.8
Resultant V_RMS = 1.8
