GEMINI SOUTH WIND TEST DATA CODE ID = p09060hh

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: half open

(max wind = 20 m/s)

At +X: Resultant 6.4 m/s
U= 5.3 V= -.5 W= .6
Resultant V_RMS = 2.7

At -X: Resultant 9.3 m/s
U= 8.6 V= -1.2 W= 1.8
Resultant V_RMS = 1.7

At -Y: Resultant 4.2 m/s
U= 3.3 V= -.1 W= -.3
Resultant V_RMS = 1.8

At M2: Resultant 2.1 m/s
U= -.6 V= .2 W= .2
Resultant V_RMS = 1.0

At Dome: Resultant 18.3 m/s
U= 14.5 V= -1.3 W= 10.8
Resultant V_RMS = 1.6
