Gemini South Wind Test Data and Analysis

GEMINI SOUTH WIND TEST DATA CODE ID = c18030oc

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: closed

At +X: Resultant .9 m/s
U= -.4 V= .3 W= .3
Resultant V_RMS = .5

At -X: Resultant 4.7 m/s
U= 1.2 V= -4.3 W= .1
Resultant V_RMS = 1.9

At -Y: Resultant 1.4 m/s
U= .2 V= .2 W= .8
Resultant V_RMS = .5

At M2: Resultant 1.8 m/s
U= .8 V= -.9 W= .1
Resultant V_RMS = .8

At Dome: Resultant 3.8 m/s
U= -.1 V= -1.7 W= 1.0
Resultant V_RMS = 1.9
