GEMINI SOUTH WIND TEST DATA CODE ID = c09060co

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 4.5 m/s
U= -4.0 V= .9 W= 1.3
Resultant V_RMS = 1.3

At -X: Resultant 3.2 m/s
U= -2.7 V= -.4 W= -.1
Resultant V_RMS = 1.3

At -Y: Resultant 1.8 m/s
U= -.3 V= .2 W= 1.1
Resultant V_RMS = .8

At M2: Resultant 3.9 m/s
U= -2.5 V= -.6 W= 1.6
Resultant V_RMS = 1.4

At Dome: Resultant 3.2 m/s
U= 1.1 V= -1.3 W= 1.1
Resultant V_RMS = 1.2
