Abstract:

The exhaust flow from the funnel of the RAN Amphibious Heavy Lift Ship has been investigated visually in a low-speed wind tunnel, using a 148 scale model. The effectiveness of the funnel as designed was found to be unsatisfactory and a funnel configuration, increased in height by 4.57 metres 15 feet, was then developed which eliminated contamination of a helicopter parked on the aft landingservicing deck for the selected test conditions.
