Method of defining gas turbine engine control ratings

Abstract:

A disclosed control system and method of controlling a gas turbine engine utilizes a thrust rating schedule generated from airframe selected requirements. The system utilizes a generic logic structure for ratings combined with simple selection logic to customize rating schedules for multiple airframe customers. The use of a common generic logic structure to generate rating schedules for different airframe manufacturers reduces software design effort, memory consumption, and processor throughput requirements.
