The acoustic treatment requirement for jet engine nacelle inner flowpath leads to using perforated skin.
Formerly in light alloy these skins are now composite and new techniques have been developped to achieve the perforation.
After reviewing different possible techniques (mandrel tool, abrasion, stamping, mechanical drilling,…) one process is chosen and described in terms of skin mechanical properties, cost, and production facilities.
