GEMINI SOUTH WIND TEST DATA CODE ID = d00060hh

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

  • Wind attack direction to SLIT = 000 degree Azimuth angle
  • Zenith angle = 60 degree (30 degree Elevation)
  • Upwind gate : half open
  • Downwind gate: half open

(max wind = 20 m/s)

At +X: Resultant 1.9 m/s
U= .6 V= -.5 W= -.1
Resultant V_RMS = .8

At -X: Resultant 4.3 m/s
U= 2.6 V= 2.7 W= .1
Resultant V_RMS = 1.9

At -Y: Resultant 2.4 m/s
U= 1.8 V= -.6 W= -.7
Resultant V_RMS = 1.2

At M2: Resultant 7.0 m/s
U= 3.9 V= 5.3 W= -.4
Resultant V_RMS = 3.4

At Dome: Resultant 11.9 m/s
U= 3.7 V= 9.2 W= 6.7
Resultant V_RMS = .4
