GEMINI SOUTH WIND TEST DATA CODE ID = p04530co

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

  • Wind attack direction to SLIT = 045 degree Azimuth angle
  • Zenith angle = 30 degree (60 degree Elevation)
  • Upwind gate : closed
  • Downwind gate: open

At +X: Resultant 1.7 m/s
U= -.3 V= -.9 W= .2
Resultant V_RMS = 1.0

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

At -Y: Resultant .8 m/s
U= .2 V= .2 W= .3
Resultant V_RMS = .4

At M2: Resultant 1.6 m/s
U= .1 V= -.2 W= 1.2
Resultant V_RMS = .7

At Dome: Resultant 14.5 m/s
U= 9.2 V= 5.8 W= 9.5
Resultant V_RMS = 1.6
