Nonlinear Dynamic Simulation of Single- and Multispool Core Engines, Part 11: Simulation, Code Validation Academic Article uri icon

abstract

  • In order to ensure the capability, accuracy, robustness, and reliability of the computational method discussed in Part I of this article, comprehensive critical performance assessment and validation tests were performedand are presented in Part II. The dynamic behavior of a subject engine is calculated by solving a number ofsystems of partial differential equations, which describe the unsteady behavior of the individual components.As representatives, three different transient cases with zero-, single-, and multispool thrust and power-generationengines were simulated. The transient cases range from operating with a prescribed fuel schedule, to extremeload changes, to generator and turbine shutdown. © 1994 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
