Special Operators Note
4th Feb 2006
The 3D balance system is still not functioning correctly. Despite several repair attempts, the model breakup in Dec 2005 seems to have permanently damaged some of these components. Repair attempts will continue but at present only 2D flow testing can be performed.
16th March 2006 2D Flow Balance calibrations checked. Calibration factors 1.0 +- 0.01 (accuracy better than 1%)
July 2006Scanivalue pressure recording system installed. Maximum of 181 static ports. Calibration and Verificaiton of system performed. Accuracy better than 1%.
July - August 2007Installation of new support system. Magnetic levitation devices to maintain wing position without interference or additional drag. New system allows wings which are less than the width of the tunnel to be tested accurately. Minimum span limit 1.5m to fit to mount system. 3D flow testing is now again fully operational.
Sept 2008Complete re-calibration carried out. Investigations of model span effects and corrections done in tunnel. Spans < 80% of width of tunnel follow simple correction theory for wt effects on results.
Dec 2010Catastrophic failure of turbine model. Tunnel closed for cleaning. OHS inspection complete, additional safety features added.
