Item Open Access Calibration test report for the phone-or 3D optical energy density probe(2004) Halim, Dunant; Petersen, Dick; Cazzolato, Benjamin Seth; School of Mechanical EngineeringThis report contains the calibration tests undertaken on the Phone-Or 3D optical Energy Density probe. A number of tests were performed for testing the calibration for the omni-directional pressure and 3-axis pressure gradient measurements. The calibration results were found to be generally consistent with the calibration specifications provided by the manufacturer.Item Open Access Investigation of passive control devices for potential application to a launch vehicle structure to reduce the interior noise levels during launch: Final report for stage 2(2001) Hansen, Colin Henry; Zander, Anthony Charles; Cazzolato, Benjamin Seth; Morgans, Rick C.; School of Mechanical EngineeringItem Open Access Investigation of passive control devices for potential application to a launch vehicle structure to reduce the interior noise levels during launch: Preliminary report for stage 2(2001) Hansen, Colin Henry; Zander, Anthony Charles; Cazzolato, Benjamin Seth; Morgans, Rick C.; School of Mechanical EngineeringItem Open Access The phone-or 3D optical energy density probe: calibration test report of the modified/re-calibrated probe(2004) Halim, Dunant; Petersen, Dick; Cazzolato, Benjamin Seth; School of Mechanical EngineeringThis report discusses the results from the second calibration test performed on the Phone-Or 3D optical Energy Density probe. The first calibration test found several performance issues associated with high level of noise in the Phone-Or probe. Since then, the Phone-Or manufacturer has addressed those issues by modifying and re-calibrating the probe. To investigate the current performance of modified/re-calibrated probe, a second calibration test was performed in the Anechoic chamber at the University of Adelaide. The test results show that the Phone-Or probe's performance has improved considerably with its self-noise level, particularly due to 50 Hz harmonics, been reduced significantly.
