METHODS AND SYSTEMS TO FACILITATE OVER-SPEED PROTECTION

An over-speed protection system (40) for a gas turbine engine (10) including a rotor (24) is provided. The over-speed protection system includes a fuel throttling/shutoff valve (50) coupled to a fuel supply coupled to the gas turbine engine, a first fuel system interface (56) coupled to the fuel thr...

Beschreibung
Zusammenfassung:	An over-speed protection system (40) for a gas turbine engine (10) including a rotor (24) is provided. The over-speed protection system includes a fuel throttling/shutoff valve (50) coupled to a fuel supply coupled to the gas turbine engine, a first fuel system interface (56) coupled to the fuel throttling/shutoff valve, the first fuel system interface configured to provide the throttling/shutoff valve with a signal indicative of an over-speed condition, a second fuel system interface (58) serially coupled to the first fuel system interface, the second fuel system interface configured to provide the throttling/shutoff valve with a signal indicative of an over-speed condition, and a control system (100) configured to identify an occurrence of an over-speed condition and to provide the first fuel system interface and the second fuel system interface with a signal corresponding to such an occurrence.
