Abstract

When an aircraft is on the ground or parked at the airport, the auxiliary power unit (APU) is switched on to supply conditioned air to the cabin or to provide electric power for aircraft systems. But an APU tends to produce a loud unwanted noise every time it is used, and this can prove to be quite troublesome for the ground crew. So, to reduce this noise, a muffler is usually fitted in the APU’s exhaust. This study presents a literature review on different types and aspects of the muffler as well as the performance parameters that are required for an efficient noise attenuation for the APU. Also, in addition to the muffler materials, various tools and software necessary for muffler design and numerical calculations have also been described. This study also encapsulates the recent vital works done on the APU’s muffler.
