FRONT PART FOR NACELLE OF PROPULSION UNIT OF AN AIRCRAFT COMPRISING A MAIN CHANNEL FOR PROPAGATION OF FORCES BETWEEN AN AIR INTAKE LIP AND A REAR SKIN OF AN ACOUSTIC PANEL

摘要

The invention relates to a front part of an aircraft propulsion unit nacelle, comprising an air intake lip (1), an acoustic panel (3), and a rigid connection between the acoustic panel (3) and the air intake lip (1). The acoustic panel has a resistive surface (31) and a rear skin (34), and the rigid connection is formed between the air intake lip (1) and the rear skin (34) of the acoustic panel (3). so as to form a force propagation path between said air intake lip and said rear skin (34). This configuration frees design constraints which makes it possible to increase the acoustic treatment zone (C) towards the The invention also relates to an aircraft propulsion unit comprising a nacelle having such an anterior part.
