Gemini South Wind Test Data and Analysis

GEMINI SOUTH WIND TEST DATA CODE ID = q04515cc

Average and RMS wind pressures and average wind velocities were calculated from the wind test in the following conditions:

Wind attack direction to SLIT = 045 degree Azimuth angle
Zenith angle = 15 degree (75 degree Elevation)
Upwind gate : closed
Downwind gate: closed

At +X: Resultant .5 m/s
U= .2 V= -.1 W= .1
Resultant V_RMS = .2

At -X: Resultant .8 m/s
U= .2 V= .0 W= -.1
Resultant V_RMS = .4

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

At M2: Resultant 1.6 m/s
U= 1.1 V= -.5 W= .9
Resultant V_RMS = .6

At Dome: Resultant 34.1 m/s
U=-19.7 V= 19.7 W=-19.7
Resultant V_RMS = .6
