ABSTRACT:
A quick change connection is provided for attaching a bracket and liner subassembly to convergent flaps and seals in an adjustable nozzle for a gas turbine engine. A threaded attachment member has a t-shaped head that is secured to prevent rotation by a washer. The washer is held in place in the convergent flaps and seals by spring fingers in a slot. By utilizing the washer, a simple threaded connection can be utilized even though the threaded attachment member must extend to a radially outer surface of the convergent flaps and seals, while a nut is threaded onto the threaded attachment member radially inwardly of the convergent flaps and seals. The washer prevents rotation of a head of the threaded attachment member, and thus allows the nut to be easily tightened to secure the components. This also facilitates maintenance as the threaded nut can be easily removed from the threaded attachment for replacement.
