GEMINI SOUTH WIND TEST DATA CODE ID = t04530co

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 : closed
  • Downwind gate: open

At +X: Resultant 5.2 m/s
U= -4.0 V= 2.7 W= 1.5
Resultant V_RMS = .8

At -X: Resultant 2.4 m/s
U= 1.6 V= -1.4 W= 1.1
Resultant V_RMS = .1

At -Y: Resultant 4.3 m/s
U= -4.0 V= 1.1 W= .3
Resultant V_RMS = 1.0

At M2: Resultant 1.6 m/s
U= .6 V= .1 W= .5
Resultant V_RMS = .8

At Dome: Resultant 3.8 m/s
U= -.4 V= .4 W= .7
Resultant V_RMS = 2.1
