Ceramic Matrix Composite Nozzle Mounted With a Strut and Concepts Thereof

摘要

A nozzle assembly is provided which is, in part, formed of a low coefficient of thermal expansion material. The assembly includes a nozzle fairing formed of the low coefficient of thermal expansion material and includes a metallic strut extending radially through the nozzle fairing. Load is transferred from the nozzle fairing to a static structure in either of two ways: first, the strut may receive the load directly and/or second, load may be transferred from the nozzle fairing to at least one of the inner and outer support rings. Further, the nozzle fairing and strut may allow for internal airflow for cooling.

1. A nozzle segment assembly, comprising:
an outer support ring and an inner support ring; a nozzle fairing formed of a low coefficient of thermal expansion material having an outer band and an inner band; said nozzle fairing further having a vane extending between said outer band and said inner band; a metallic strut extending between said outer support ring and said inner support ring, said strut allowing for load transfer between at least one pair of said nozzle fairing and said strut or said nozzle fairing and at least one of an inner and outer support ring; said metallic strut extending through said nozzle fairing and allowing growth of said strut through said vane.
