US Patent:

6619027, Sep 16, 2003

Filed:

Oct 13, 2000

Appl. No.:

09/687325

Inventors:

Thomas George Busch - Cincinnati OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02C 928

US Classification:

60 39281

Abstract:

A rotor overspeed protection system for a gas turbine engine controls engine fuel flow to prevent an engine rotor from over-speeding. The engine fuel metering system includes a fuel metering valve in flow communication with a fuel shutoff valve and a fuel bypass valve. The rotor protection system includes an overboost servovalve and a soleniod valve coupled to the fuel metering system and to an independent speed sensing system. In operation, servovalve can control the metered fuel flow to engine independently of the fuel metering valve to facilitate reducing rotor overspeeds and overboosts.
