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

Abstract
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.
