GEMINI SOUTH WIND TEST DATA CODE ID = q09015hh

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 = 15 degree (75 degree Elevation)
  • Upwind gate : half open
  • Downwind gate: half open
FIGURE SUMMARY

TOP LEFT:
AVERAGE Wind pressure
Range= +/- 5.0 Pa

TOP RIGHT:
RMS wind pressure
Range= 0 - 3.0 Pa

BOTTOM:
AVERAGE Wind speeds
(max wind = 20 m/s)

At +X: Resultant 5.0 m/s
U= 4.7 V= .1 W= 1.0
Resultant V_RMS = 1.4

At -X: Resultant 7.2 m/s
U= 6.8 V= .7 W= 1.6
Resultant V_RMS = 1.5

At -Y: Resultant 6.8 m/s
U= 6.6 V= .6 W= .2
Resultant V_RMS = 1.3

At M2: Resultant 1.2 m/s
U= -.6 V= -.3 W= .0
Resultant V_RMS = .7

At Dome: Resultant 11.5 m/s
U= 8.6 V= .8 W= 7.4
Resultant V_RMS = 1.2
