Gemini South Wind Test Data and Analysis

GEMINI SOUTH WIND TEST DATA CODE ID = d09060hh

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

At +X: Resultant 9.3 m/s
U= -9.1 V= .6 W= 1.3
Resultant V_RMS = 1.0

At -X: Resultant 7.6 m/s
U= -7.5 V= .4 W= .3
Resultant V_RMS = 1.4

At -Y: Resultant 4.1 m/s
U= -3.6 V= .3 W= -.7
Resultant V_RMS = 1.6

At M2: Resultant 2.0 m/s
U= 1.4 V= .2 W= -.6
Resultant V_RMS = .9

At Dome: Resultant 3.1 m/s
U= 2.1 V= -1.6 W= 1.0
Resultant V_RMS = .9
