GEMINI SOUTH WIND TEST DATA CODE ID = q13560hc

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

(max wind = 20 m/s)

At +X: Resultant 1.3 m/s
U= -.5 V= -1.0 W= .1
Resultant V_RMS = .6

At -X: Resultant 4.1 m/s
U= 1.1 V= -3.5 W= .7
Resultant V_RMS = 1.5

At -Y: Resultant .8 m/s
U= -.2 V= .0 W= -.3
Resultant V_RMS = .3

At M2: Resultant 7.7 m/s
U= 3.3 V= -6.4 W= 2.3
Resultant V_RMS = 1.2

At Dome: Resultant 10.1 m/s
U= 4.1 V= -7.5 W= 3.7
Resultant V_RMS = 3.3
