Validation of F/A-22 Propulsion System T&E Instrumentation Using Modeling and Simulation

摘要

With the long-term goal of developing joint ground/flight modeling and simulation capabilities, Arnold Engineering Development Center and the Air Force Flight Test Center have teamed to apply these data analysis tools to two major propulsion flight test programs, the F/A-22 and the F-35. The emphasis of this paper is on the development and application of a nonlinear, aerothermodynamic, component-level model that serves as the basis for the model-based analysis and fault identification process. Model-to-data comparisons and model-based fault detection and analysis results for F/A-22/F119 propulsion ground and flight tests are also presented for a variety of flight conditions.
