Gemini South Wind Test Data and Analysis

GEMINI SOUTH WIND TEST DATA CODE ID = d09060co

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 : closed
Downwind gate: open

At +X: Resultant 4.8 m/s
U= -4.2 V= .7 W= 1.5
Resultant V_RMS = 1.5

At -X: Resultant 3.3 m/s
U= -2.7 V= -.9 W= -.1
Resultant V_RMS = 1.4

At -Y: Resultant 2.5 m/s
U= .0 V= -.1 W= 2.0
Resultant V_RMS = 1.0

At M2: Resultant 4.9 m/s
U= -3.0 V= -1.6 W= 2.5
Resultant V_RMS = 1.5

At Dome: Resultant 3.5 m/s
U= 1.2 V= -1.4 W= 1.4
Resultant V_RMS = 1.4
