GEMINI SOUTH WIND TEST DATA CODE ID = d00060oh

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 : open
  • Downwind gate: half open
FIGURE SUMMARY

(max wind = 20 m/s)

At +X: Resultant 2.8 m/s
U= 2.1 V= -1.0 W= .3
Resultant V_RMS = 1.0

At -X: Resultant 5.6 m/s
U= 3.7 V= 4.0 W= .4
Resultant V_RMS = 1.3

At -Y: Resultant 2.4 m/s
U= 2.0 V= -.8 W= .1
Resultant V_RMS = 1.0

At M2: Resultant 4.4 m/s
U= 2.3 V= 3.1 W= -.4
Resultant V_RMS = 3.0

At Dome: Resultant 11.1 m/s
U= 3.0 V= 9.2 W= 5.4
Resultant V_RMS = .3
