GEMINI SOUTH WIND TEST DATA CODE ID = d09060ho

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 : half open
  • Downwind gate: open

(max wind = 20 m/s)

At +X: Resultant 9.3 m/s
U= -9.0 V= .2 W= 1.7
Resultant V_RMS = 1.1

At -X: Resultant 7.9 m/s
U= -7.7 V= .4 W= .4
Resultant V_RMS = 1.4

At -Y: Resultant 3.6 m/s
U= -3.4 V= -.4 W= .2
Resultant V_RMS = 1.1

At M2: Resultant 2.3 m/s
U= 1.3 V= -.3 W= -.9
Resultant V_RMS = 1.0

At Dome: Resultant 3.1 m/s
U= .3 V= -.7 W= 1.3
Resultant V_RMS = 1.3
