Abstract (en)
[origin: EP1818617A1] The wall has a set of deflectors (16) forming a heat shield and mounted in each of a set of apertures (12). The deflectors has a circular aperture (17) centered on an axis of symmetry of fluid injection systems (14). Each deflector comprises two deformations (20) forming chicanes for through-flow of a cooling air flow. The deformations force the flow of cooling air for the deflectors to flow radially around the fuel injection systems. The deformations extend radially on both sides of the circular aperture to allow passage of the fuel injection systems.
