Abstract
Divergent petal arrangement for convergent-divergent nozzles for application in aircraft engines, where the divergent section comprises master divergent petals (3) and slave divergent petals (4), having the latter a bent cross section with the concave side facing the gas, and with the possibility of having a number of hangers (7) mounted on the slave divergent petals (4) and presenting hooks (12) at the ends of said hangers (7), said hooks interacting with hanger stops (5) provided on the master divergent petals (3), hence limiting the side movement of the slave divergent petals (4).
