Hollow nozzle actuating ring

摘要

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 apart coaxial forward and aft walls, struts axially extending between and structurally joining together the forward and aft walls, and a ring stiffening for decreasing the effective ring bending and torsional length of at least one of the forward and aft walls between the struts. Stiffening structure is provided for spreading out loads transferred from the struts to one of the forward and aft walls using structural braces extending diagonally between the struts and one of the forward and aft walls.
