DEVICE FOR DE-ICING THE INLET OF A NACELLE OF AN AIRCRAFT ENGINE, METHOD FOR PRODUCING SUCH A DE-ICING DEVICE, AND AIRCRAFT ENGINE NACELLE PROVIDED WITH SUCH A DE-ICING DEVICE

摘要

The invention relates to a de-icing device comprising a piccolo tube (43) built into the front wall (37) defining the inner volume of the perforated front lip (36). The piccolo tube (43) is in contact with an alveolar noise-reduction structure (44) that has perforations and channels for the circulation of hot air supplied by the piccolo tube (43), the hot de-icing air spreading through the perforations and channels of the alveolar structure (44), to the perforations facing the front lip (36).
