Engine operations support systems and methods for reducing fuel flow
First Claim
1. An operations system for an engine receiving fuel, comprising:
- a diagnostic engine model unit configured to receive engine data from the engine and to generate diagnostics data based on the engine data, the diagnostics data including scalars;
an engine-specific model unit coupled to the diagnostic engine model unit and configured to receive the scalars and the engine data,the engine-specific model unit including a fuel flow calculation module configured to determine a current fuel flow for the engine and a set point module configured to generate set point information for the engine using a thermodynamic model configured to reduce the current fuel flow to the engine, the thermodynamic model being based on component maps associated with the engine, wherein the fuel flow calculation module calculates the current fuel flow from the engine data using the thermodynamic model; and
a data storage unit coupled to the engine-specific model unit and configured to store the set point information.

Abstract
An operations support system is provided for an engine receiving fuel. The system includes a diagnostic engine model unit configured to receive engine data from the engine and to generate diagnostics data based on the engine data, the diagnostics data including scalars. The system further includes an engine-specific model unit coupled to the diagnostic engine model unit and configured to receive the scalars and the engine data. The engine-specific model unit includes a fuel flow calculation module configured to determine a current fuel flow for the engine and a set point module configured to generate set point information for the engine using a thermodynamic model that reduces the current fuel flow to the engine, the thermodynamic model being based on component maps associated with the engine. The system further includes a data storage unit coupled to the engine-specific model unit and configured to store the set point information.
