GEMINI SOUTH WIND TEST DATA CODE ID = q04560oh

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

  • Wind attack direction to SLIT = 045 degree Azimuth angle
  • Zenith angle = 60 degree (30 degree Elevation)
  • Upwind gate : 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 6.2 m/s
U= 5.9 V= -1.1 W= .7
Resultant V_RMS = 1.5

At -X: Resultant 7.8 m/s
U= 5.9 V= 4.4 W= 1.9
Resultant V_RMS = 1.4

At -Y: Resultant 3.5 m/s
U= 3.0 V= .0 W= -1.0
Resultant V_RMS = 1.4

At M2: Resultant 2.3 m/s
U= -1.0 V= -.3 W= -.2
Resultant V_RMS = 1.2

At Dome: Resultant 12.2 m/s
U= 8.6 V= 4.5 W= 7.2
Resultant V_RMS = 1.2
