GEMINI SOUTH WIND TEST DATA CODE ID = q13545ch

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

  • Wind attack direction to SLIT = 135 degree Azimuth angle
  • Zenith angle = 45 degree (45 degree Elevation)
  • Upwind gate : closed
  • Downwind gate: half open

(max wind = 20 m/s)

At +X: Resultant 1.1 m/s
U= -.7 V= .6 W= .2
Resultant V_RMS = .6

At -X: Resultant .9 m/s
U= -.7 V= -.1 W= -.3
Resultant V_RMS = .4

At -Y: Resultant .6 m/s
U= -.3 V= -.1 W= -.1
Resultant V_RMS = .4

At M2: Resultant .8 m/s
U= -.1 V= -.1 W= .4
Resultant V_RMS = .4

At Dome: Resultant 11.1 m/s
U= 6.0 V= -7.4 W= 5.1
Resultant V_RMS = 3.2
