Gemini South Wind Test Data and Analysis

GEMINI SOUTH WIND TEST DATA CODE ID = c18030oo

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

At +X: Resultant 6.7 m/s
U= -3.4 V= -5.5 W= .7
Resultant V_RMS = 1.6

At -X: Resultant 3.9 m/s
U= .7 V= -3.4 W= .0
Resultant V_RMS = 1.9

At -Y: Resultant 1.8 m/s
U= -.7 V= -.3 W= -.4
Resultant V_RMS = .9

At M2: Resultant 3.9 m/s
U= -1.2 V= -2.9 W= 1.2
Resultant V_RMS = 1.5

At Dome: Resultant 3.0 m/s
U= .2 V= -.6 W= 1.2
Resultant V_RMS = 1.6
