GEMINI SOUTH WIND TEST DATA CODE ID = p18030hc

Average and RMS wind pressures and average wind velocities were calculated from the wind test in the following conditions:

  • Wind attack direction to SLIT = 180 degree Azimuth angle
  • Zenith angle = 30 degree (60 degree Elevation)
  • Upwind gate : half open
  • Downwind gate: closed
FIGURE SUMMARY

(max wind = 20 m/s)

At +X: Resultant 1.1 m/s
U= -.7 V= -.2 W= .4
Resultant V_RMS = .4

At -X: Resultant 3.8 m/s
U= .8 V= -3.2 W= .1
Resultant V_RMS = 1.7

At -Y: Resultant 1.5 m/s
U= .9 V= -.2 W= .9
Resultant V_RMS = .6

At M2: Resultant 1.2 m/s
U= .1 V= .1 W= .4
Resultant V_RMS = .8

At Dome: Resultant 6.4 m/s
U= 1.2 V= -3.6 W= 2.4
Resultant V_RMS = 2.8
