A feeder duct assembly for a gas turbine engine, which negates the need for a ball or axial joint in the duct for required for flexibility under thermal loading. The feeder duct assembly of the present innovation comprises an end fitting designed to meet flexibility requirements without compromising dynamic performance of the system with added weight from ball or axial joints in the ducts.

Feeder duct assembly with flexible end fittings

A turbine engine duct assembly including a joint assembly having an outer shroud, a bellows, a flared tube, a backing ring, and a kinematic ring. The joint assembly provides for dynamic movement of the duct assembly during operation of the engine. Such dynamic movement can be resultant of vibrational forces or thermal expansion of the engine. The joint assembly permits such dynamic movement without excessive system stiffness.
