GEMINI SOUTH WIND TEST DATA CODE ID = d09060ch

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: half open

(max wind = 20 m/s)

At +X: Resultant 6.1 m/s
U= -5.6 V= .6 W= 1.6
Resultant V_RMS = 2.0

At -X: Resultant 5.2 m/s
U= -4.8 V= .3 W= -.2
Resultant V_RMS = 1.9

At -Y: Resultant 2.4 m/s
U= .2 V= -.3 W= .5
Resultant V_RMS = 1.1

At M2: Resultant 2.3 m/s
U= -.2 V= -.1 W= -.9
Resultant V_RMS = 1.0

At Dome: Resultant 2.7 m/s
U= 1.7 V= -1.0 W= .8
Resultant V_RMS = .9
