GEMINI SOUTH WIND TEST DATA CODE ID = p04530oc

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 = 30 degree (60 degree Elevation)
  • Upwind gate : open
  • Downwind gate: closed

At +X: Resultant 3.3 m/s
U= 1.3 V= -1.1 W= 1.5
Resultant V_RMS = 1.5

At -X: Resultant 8.7 m/s
U= 4.9 V= 6.6 W= 1.6
Resultant V_RMS = 2.1

At -Y: Resultant 2.2 m/s
U= 1.1 V= -.1 W= .9
Resultant V_RMS = 1.2

At M2: Resultant 3.4 m/s
U= -1.3 V= -.1 W= 1.4
Resultant V_RMS = 1.4

At Dome: Resultant 14.4 m/s
U= 7.5 V= 8.8 W= 8.2
Resultant V_RMS = 1.7
