Abstract: A centerbody assembly includes a center tube, a forward bulkhead, an aft bulkhead, at least one baffle, and an outer skin. The center tube extends circumferentially about an axial centerline. The center tube extends between and to a first axial tube end and a second axial tube end. The forward bulkhead is mounted to the center tube at the first axial tube end. The aft bulkhead is mounted to the center tube at the second axial tube end. The at least one baffle extends axially from the forward bulkhead to the aft bulkhead. At least the forward bulkhead, the aft bulkhead, or the at least one baffle include one or more thermal beads. The outer skin circumscribes the center tube, the forward bulkhead, the aft bulkhead, and the at least one baffle to form an acoustic cavity radially inside the outer skin.

Abstract: The system separates the common administrative functions from the supervisory host applications. Each administrative function is performed by a separate administrative process that is dedicated to that function and is accessible by all the supervisory application. Thus when a supervisory process requires performance of an administrative function, it invokes operation of the corresponding administrative process. With this arrangement, only a single copy of each administrative process needs to be maintained. All communications between the administrative processes, the switching platform and/or the supervisory applications are routed through a gateway process. The gateway process then forwards the message to the appropriate process or switch and later returns the any reply results to the requesting process or application.
