Divergent petal arrangement for convergent-divergent nozzles with thrust vectoring capability through changes in the divergent section geometry, in which the position of each slave divergent petals,is determined by a centering mechanism,, made up by two centering bars,and,that slide across the sled elements,and,of the master divergent petals,fix a centered axial position between divergent master petals,and by a hanger element,that collides with the stop elements,of the master divergent petals limits the displacement to another axial position, avoiding at the same time and in conjunction with the centering mechanism,the displacement of the slave divergent petal,away from the master petals,when the pressure forces act from the air towards the gas side.

Cross bar centering mechanism for slave petals in covergent divergent nozzles with variable geometry

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.
