Real-Time Modeling Methods for Gas Turbine Engine Performance
AIR4548B
This SAE Aerospace Information Report (AIR) provides a review of real-time modeling methodologies for gas turbine engine performance. The application of real-time models and modeling methodologies are discussed. The modeling methodologies addressed in this AIR concentrate on the aerothermal portion of the gas turbine propulsion system. Characteristics of the models, the various algorithms used in them, and system integration issues are also reviewed. In addition, example cases of digital models in source code are provided for several methodologies.
Rationale:
This document has been updated to include an advancement in aerothermodynamic real time model transient simulation methodology. In recent years, there has been an emphasis on using a single model for both non-real-time and real-time simulation, without any loss in accuracy and without the extra software maintenance efforts associated with having a separate real-time model. Discussion of a method to optimize the equation structure of the non-real-time aerothermal model for real-time execution is included.
