Modifying Combat Aircraft with Fin-lined Nozzles to Reduce Noise Pollution from Overflights

1 Assoc Prof Jamus Jerome Lim asked the Minister for Defence whether the RSAF has conducted research on modifying combat aircraft with fin-lined nozzles to reduce noise pollution from overflights and, if not, whether it will do so.

Dr Ng Eng Hen: There are currently no aircraft or aircraft engine manufacturers that have certified or successfully incorporated the use of fin-lined nozzles into their engine design. The Republic of Singapore Air Force (RSAF) will continue to monitor the development of this and other technologies and evidence of their ability to also meet operational requirements in a cost-effective way.
