Acoustic barrel for aircraft engine nacelle including crack and delamination stoppers

摘要

An acoustic inner barrel (10) for an aircraft engine nacelle (1) inlet is constructed from a composite material and is formed as a single, 360-degree annular segment. The barrel includes an inner skin (12), an outer skin (14), a cellular core (16) disposed between the inner skin and the outer skin, and at least one crack and delamination stopper (50) extending radially from the inner skin to the outer skin.
