US Patent:

48541206, Aug 8, 1989

Filed:

Dec 14, 1987

Appl. No.:

7/132181

Inventors:

Neil M. Nelson - Winterhaven FL
William A. Sponzilli - Sarasota FL
Quitman W. Lott - Lakeland FL

Assignee:

CEF Industries, Inc. - Haines City FL

International Classification:

F02C 700
F01D 2536

US Classification:

60 3902

Abstract:

The present invention relates to a device for extending the performance life of a gas turbine engine by rotating the turbine after shutdown to achieve uniform cooling. The apparatus includes a motor, a high ratio gearset engaged with the motor, an overridable coupling means engaging the gearset with an accessory shaft of the turbine, and a logic circuit. The circuit determines when the engine has been shut down and continues to rotate the turbine for a predetermined period of time. If an external force interferes with the post-shutdown turning, the circuit will sense that force and compensate for it.
