Abstract: A center body attachment system may comprise an engine flange, a center body mounting assembly, and a center body. The center body mounting assembly may retain the center body and the engine flange in slidable engagement, whereby the engine flange and the center body may expand and contract at different rates. The center body may comprise a housing. The housing may comprise a floating counter bore, a spring supporting the floating counter bore, and a slider radially inward of the floating counter bore and retained within the housing by a nut.

Abstract: A center body attachment system is disclosed. A center body attachment system may permit a center body to be attached to an engine, while permitting various components to expand and contract independently when heated and cooled. In this manner, a center body may be made of a material having a different coefficient of thermal expansion than various components of the engine, such as an engine flange to which the center body is mounted. Thus, a center body may be made of materials having advantageous different material properties, for example, lighter and/or more heat-tolerant materials.
