Abstract
Aircraft engines include an engine shaft, an air bearing assembly arranged to selectively support the engine shaft, and a shaft support assembly arranged to selectively support the engine shaft. The shaft support assembly includes a shaft support for selectively engaging and disengaging the engine shaft, a centering shaft that supports the shaft support at one end, an actuator operably coupled to an opposite end of the centering shaft, and a biasing member arranged to apply force to engage the shaft support with the engine shaft. The actuator is configured to apply a force to the centering shaft to overcome the biasing force and disengage the shaft support from the engine shaft in response to an operational parameter exceeding a minimum operational value, and when the shaft support is disengaged from supporting the engine shaft, the engine shaft is supported by the air bearing assembly.
