Latest Patents

Whittle is named on 1 patent: “Retaining Split Ring Stack for Ceramic Matrix Composite Components and Method.” The patent describes a two-ring arrangement for retaining a ceramic matrix composite gas-path component. An outer split ring fits into a groove in a support structure and has scallops along its inner diameter. An inner split ring has tabs that engage those scallops and a surface positioned to contact the composite component.

The arrangement allows the cooler outer ring to move radially with the support structure. The inner ring can be sized to help limit radial deflection and hoop stress in the ceramic matrix composite component.
