Abstract
A convergent-divergent nozzle with an exit area control mechanism includes convergent and divergent petals extending from a nozzle structure on which a synchronising ring is allowed to rotate and to move in a radial direction. Angled lever arms pivot on the nozzle structure and extend from the synchronising ring to compression struts that connect with the divergent petals so that, when the synchronising ring rotates around the nozzle structure, the rotation is converted by the angled lever arms into a predominantly axial displacement of the compression struts, resulting in opening or closure of the divergent petals.
