GEMINI SOUTH WIND TEST DATA CODE ID = d00060ho

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 : half open
  • Downwind gate: open

(max wind = 20 m/s)

At +X: Resultant 2.9 m/s
U= -.9 V= 1.4 W= -.8
Resultant V_RMS = 1.2

At -X: Resultant 3.9 m/s
U= 2.4 V= 2.3 W= .0
Resultant V_RMS = 1.7

At -Y: Resultant 1.8 m/s
U= .5 V= -.6 W= -.8
Resultant V_RMS = .9

At M2: Resultant 7.3 m/s
U= 4.3 V= 5.4 W= -.4
Resultant V_RMS = 3.0

At Dome: Resultant 12.1 m/s
U= 3.6 V= 9.2 W= 6.9
Resultant V_RMS = .3
