Hollow nozzle-actuating ring

A hollow actuating ring and apparatus for actuating and/or vectoring the flaps of an aircraft gas turbine engine nozzle by transferring actuation loads from a small number of actuators to a greater number of pivotal divergent flap members of the nozzle. The actuating ring has a generally hollow annular structure including axially spaced aprt coaxial forward and aft walls, joining struts axially extending between and structurally joining together the forward and aft walls, and a ring stiffening structure for decreasing the effective ring bending and torsional length (L) of at least one of the forward and aft walls between the joining struts. Stiffening structure is provided for spreading out loads transferred from the joining struts to one of the forward and aft walls using structural braces extending diagonally between the joining struts and one of the forward and aft walls.
