Abstract

A gas turbine engine (20) includes a fan (42) delivering air into a bypass duct (13) defined between a nacelle (301) and an inner core housing (15). The inner core housing (15) receives a compressor section (24), a turbine section (28) and a combustor (56). The nacelle (301) has an inner periphery (141) with a forwardmost point, and receives an acoustic structure on the inner periphery (141) adjacent the forwardmost point. The acoustic structure is defined by a three dimensional array (100) of interconnected resonators (102), with the interconnected resonators (102) extending in a radial direction (R), a circumferential direction (C) and an axial direction (A) all defined about a rotational axis (A) of the engine (20), with the interconnected resonators (102) having a larger cross-sectional area central body (104), and six members (106, 108, 110, 112, 143; 198) connecting the central body (104) of the resonators (102) to adjacent resonators (102) at respective central bodies (104). A perforated face sheet (118) is inward of the three dimensional array (100) of interconnected resonators and an anti-icing system.
