The invention relates to a front part of an aircraft propulsion device compartment, comprising an air inlet lip (1), a sound insulation panel (3), and a rigid connection between the sound insulation panel (3) and the air inlet lip (1). The acoustic panel has a resistance surface (31) and a rear skin (34), and a rigid connection is formed between the air input lip (1) and the rear skin (34) of theacoustic panel (3) such that a force propagation path is formed between the air input lip and the rear skin (34). This configuration eliminates design restrictions such that a sound-deadening treatment area (C) can be increased towards the front of the nacelle. The invention also relates to an aircraft propulsion device comprising a nacelle having such a front.
本发明涉及飞行器推进装置舱的前部,其具有空气输入唇部(1)、隔音板(3)、以及隔音板(3)与空气输入唇部(1)之间的刚性连接件。隔音板具有阻力面(31)和后部蒙皮(34),刚性连接件形成于空气输入唇部(1)与隔音板(3)的后部蒙皮(34)之间,使得在所述空气输入唇部与所述后部蒙皮(34)之间形成作用力传播线路。这种构形免除设计限制条件,从而可向舱的前部增大隔音处理区域(C)。本发明还涉及包括具有这种前部的舱的飞行器推进装置。
