The body has an external wall (11) e.g. rotation wall, forming a cavity (13), and a set of orifices pierced on an upstream portion of the wall. A resonance cavity (17) forms a Helmholtz resonator. An internal wall (15) inside the external wall delimits the resonance cavity and an internal cavity (18). The internal cavity is arranged to fulfill the guiding function of degassing flow of fluid for a turbojet engine (1). A joint (16) provided between the internal and external walls forms the cavity (13) for recapturing the dilatation differentials. |
