Abstract (en)
The system has a set of non-axisymetric shaped individual pipes (1), where each pipe has a circular shaped neck (12) that receives gas from a combustion chamber (11) and a divergent section (13). The section has a trapezoidal shaped outlet section (14) provided with rectilinear radial lateral sides (14c, 14d). The section (14) has a curved outer side (14b) whose convexity is turned towards the exterior, and a rectilinear inner side (14a) that is situated nearer to a tapered axisymetric central core (2). The side (14a) has dimension smaller than a chord defined from the side (14b).
