GEMINI SOUTH WIND TEST DATA CODE ID = p09045oc

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 = 45 degree (45 degree Elevation)
  • Upwind gate : open
  • Downwind gate: closed

At +X: Resultant 3.1 m/s
U= .4 V= -1.3 W= .4
Resultant V_RMS = 1.5

At -X: Resultant 5.9 m/s
U= 5.2 V= .1 W= 1.7
Resultant V_RMS = 2.4

At -Y: Resultant 3.5 m/s
U= -2.0 V= .4 W= 2.0
Resultant V_RMS = 1.3

At M2: Resultant 6.4 m/s
U= 3.0 V= -2.3 W= 4.7
Resultant V_RMS = 1.9

At Dome: Resultant 15.0 m/s
U= 12.6 V= -.8 W= 7.8
Resultant V_RMS = 2.2
