GEMINI SOUTH WIND TEST DATA CODE ID = d09060hc

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

At +X: Resultant .8 m/s
U= -.4 V= -.2 W= -.5
Resultant V_RMS = .4

At -X: Resultant .7 m/s
U= -.2 V= .1 W= -.3
Resultant V_RMS = .3

At -Y: Resultant .8 m/s
U= -.6 V= .1 W= -.1
Resultant V_RMS = .3

At M2: Resultant 1.0 m/s
U= .7 V= -.4 W= -.3
Resultant V_RMS = .3

At Dome: Resultant 4.0 m/s
U= 3.2 V= -1.1 W= 1.5
Resultant V_RMS = 1.2
