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).

Divergent petal arrangement for a convergent-divergent aircraft engine

A load strut for divergent master petals of variable geometry nozzles, of the type which exhibit a control system constituted by three ring-like pieces, the external ring piece being divided into two half-rings, which joins the two half-rings and the corresponding divergent master petal, and which may comprise two bars joined at one end by means of spherical or universal joints to the external ring, and joined to one another, by means of a cylindrical joint, substantially perpendicular to the plane which contains the center lines of both bars and by a divergent master petal-binding transition piece, joined to the two bars by means of cylindrical joints, with sufficient clearance to allow the changes in distance between the ends of the two bars.
