中空ノズル作動リング
Document Type and Number:
Japanese Patent JP3998269
Kind Code:
B2
Abstract:
A hollow actuating ring (86) and apparatus for actuating and/or vectoring the flaps (50) of an aircraft gas turbine engine nozzle (14) by transferring actuation loads from a small number of actuators (90) to a greater number of pivotal divergent flap members of the nozzle (14). The actuating ring (86) has a generally hollow annular structure including axially spaced apart coaxial forward and aft walls (110 & 114), joining struts (118) axially extending between and structurally joining together the forward and aft walls (110 & 114), and a ring stiffening structure (124) for decreasing the effective ring bending and torsional length (L) of at least one of the forward and aft walls (110 & 114) between the joining struts (118). Stiffening structure (124) is provided for spreading out loads transferred from the joining struts (118) to one of the forward and aft walls (110 & 114) using structural braces (132) extending diagonally between the joining struts (118) and one of the forward and aft walls (110 & 114).
