GEMINI SOUTH WIND TEST DATA CODE ID = p18045ch

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

  • Wind attack direction to SLIT = 180 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 2.2 m/s
U= -.9 V= -1.2 W= .1
Resultant V_RMS = 1.3

At -X: Resultant .8 m/s
U= -.3 V= .1 W= -.1
Resultant V_RMS = .4

At -Y: Resultant .9 m/s
U= -.4 V= .1 W= .4
Resultant V_RMS = .5

At M2: Resultant 2.0 m/s
U= -1.0 V= -.4 W= .5
Resultant V_RMS = 1.1

At Dome: Resultant 8.3 m/s
U= 1.1 V= -6.2 W= 2.6
Resultant V_RMS = 3.7
