초록

A nozzle failsafe nozzle actuating system for an aircraft gas turbine engine variable exhaust nozzle having a plurality of pivotal flaps circumferentially disposed about a nozzle centerline and bounding an exhaust gas flowpath in the nozzle is provided with a number of primary actuators which are operably connected to nozzle flaps for pivoting and setting an attitude of the flaps relative to the centerline and wherein each of the primary actuators is extendable between a fully extended position and a fully retracted position, and a failsafe nozzle actuat...

청구항

[ What is claimed is:] [1.] A failsafe nozzle actuating system for an aircraft gas turbine engine comprising:a variable thrust vectoring axisymmetric exhaust nozzle having a plurality of multi-degree of freedom pivotal flaps circumferentially disposed about a nozzle centerline and bounding an exhaust gas flowpath in said nozzle,said pivotal flaps being differentially pivotal so as to have different attitudes about said nozzle centerline in a vectored configuration of said nozzle,a primary nozzle actuating means operably connected to said flaps for pivoti...
