Aircraft Engine Component Retaining Ring Thermal Expansion Management

The patent applies thermal expansion principles by selecting materials with different coefficients of thermal expansion (CTE) for specific functional purposes. The first mating section uses a material with a first CTE while the second mating section uses a material with a second CTE, allowing each component to expand at different rates during thermal cycles. This controlled differential expansion is managed through the design of the retaining structure that maintains engagement between sections despite the expansion differences, thereby preserving connection stability while allowing material selection flexibility for operational requirements.

The patent merges the retaining function into the existing mating section structure itself. The retaining structure is integrated as part of one of the mating sections rather than being a separate component, thereby preventing connection loosening while minimizing the increase in device complexity. This integration approach maintains connection stability without adding significant structural complexity to the overall assembly.

The patent employs a dynamic retaining structure that can accommodate thermal expansion movements rather than completely restraining them. The retaining structure is designed to maintain engagement between mating sections while allowing controlled movement during thermal cycles, thereby preserving connection stability without generating excessive thermal stress. This dynamic approach lets the structure adapt to thermal conditions while preventing loosening.
