AIRCRAFT NACELLE INCLUDING AN OPTIMISED ACOUSTIC PROCESSING SYSTEM

摘要

The invention relates to an aircraft nacelle including a duct (32), a peripheral wall (34), a lip (36) and a front frame (38) connecting the peripheral wall (34) and the duct (32) and defining a gap (50) with the lip (36) in which hot air can flow for treating icing, the duct (32) including a coating (44) for acoustic processing made of a composite material, characterised in that the nacelle further includes at least one element (52) made of a heat-conducting material and provided between the lip (36) and the duct (32) and ensuring the continuity of the aerodynamic surfaces of the lip (36) and the duct (32) and the propagation of heat from said gap (50) towards the back of the nacelle, said at least one element (52) comprising a coating (54) for acoustic processing made of a heat resistant material.
