The panel is capable of benefiting from forced ventilation by means of a ventilatory flow through its perforated honeycomb cells, making use of the differences in pressure on either side of the panel or along the panel. The two external walls (61E, 61I) have, for many honeycomb cells (65, 67), holes in the first wall (61E), holes (66) in the second wall (61I) and several holes (68) in the internal partitions (62) so as to allow air to circulate in different ways through the honeycomb cells to be ventilated. Use for all panels that may need to be cooled and, in particular, to the rotating wall between the hot and cold flows of a turbojet engine. |
