FIELD: transport.
SUBSTANCE: nacelle comprises panel 56 that form channel 32, peripheral wall 54 that makes inlet 36 connecting channel 32 with wall 34. Nacelle comprises also hoarfrost processing system, processing zone extending from wall 34 to channel 32, front frame 38 to confine channel 51 where in hot deicing air circulates. Channel 32 comprises coating 44 for acoustic processing. Front frame 38 comprises area of connection with inlet 36 and/or channel 32 shifted towards nacelle front. Hot air channels 50 are arranged level with inner side of inlet 38 and channel 32. Channels 50 extend beyond said connection area. Channels 50 are confined by baffle composed of insert 52 of two parts. First part 58, 70, 88 is inserted between superimposed panels and includes ledge and/or recesses to make channels 50 between panels for communication between nacelle inner and outer parts. Second part 60, 72, 90 is located opposite the panel located level with said connection area to protect its against heat and isolate hot air from acoustic processing coating 44.
EFFECT: optimised deicing system.
