Blade safety mechanism for open rotor engine system

摘要

A method and apparatus for safely handling an undesired blade event in an open rotor engine system. In one illustrative embodiment, an occurrence of an undesired blade event in an open rotor engine system is detected. Electrical energy is allowed to flow into a conductor embedded in the blade in response to the undesired blade event. The conductor is vaporized when the electrical energy flowing through the conductor heats the conductor to a temperature above a selected threshold.

主权项

1. An apparatus comprising:
a blade connected to a hub in an open rotor engine system; a conductor embedded within the blade and extending a length of an airfoil section of the blade; and an activation system configured to allow electrical energy to flow into the conductor in response to an undesired blade event such that the conductor vaporizes.
