Support means for an acoustic liner used in an auxiliary power unit exhaust muffler

摘要

The present invention provides support means for an acoustic liner in an APU exhaust system, where the acoustic liner has a tubular sidewall with an outer surface, a first longitudinal edge, a second longitudinal edge, and an axial gap formed between the first and the second longitudinal edges. The APU exhaust system includes an annular support disposed substantially symmetrically about a longitudinal axis and coupled to a portion of the acoustic liner and a linear support disposed at least partially in the acoustic liner axial gap.
