Wind Tunnel Experiments on a 1/48 Scale Model to Investigate Funnel Effectiveness of the RAN Amphibious Heavy Lift Ship,

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 1/48 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 landing/servicing deck for the selected test conditions.
