SYSTEM AND METHOD FOR SYNTHESIZING ENGINE OUTPUT POWER

A method and a system for synthesizing output power provided by an engine (10) are provided. The engine (10) comprising a compressor section (14), a combustor (16), and a turbine section (18) in serial fluid flow communication. The engine is operated and, during the operating of the engine, a pressure of fluid at an exit of the compressor section (14), a temperature upstream of the exit of the compressor section (14), and a fuel flow rate to the engine are determined. A synthesized value of output power provided by the engine (10) is determined based on a product of at least a first factor, a second factor, and a third factor, the first factor being a function of the pressure, the second factor being a function of the temperature, and the third factor being a function of the fuel flow rate. The synthesized value of output power provided by the engine (10) is output.
