The Jet Propulsion Library: Modeling and simulation of aircraft engines

Abstract

The Jet Propulsion Library is a new Modelica library that provides a foundation for modeling and simulation of jet engines, and the model-based design of integrated aircraft systems. It provides a fully rigorous foundation for sizing and performance computations, and provides a number of advantages over existing domain-specific solutions due to the use of the Modelica language. This paper provides an introduction and overview of the library and describes an application in the design of a turbo fan engine.

“…Modelica models and FMUs usually use variables expressed in SI units. Variable values may therefore differ by several orders in magnitude [SIE12]. This can yield to ill-conditioned systems which are difficult to converge.…”

“…[SIE17],Sielemann et al introduced this library dedicated to modeling and simulation of jet engines. This paper shows how the model architecting enables selecting different levels of realism of the subsystems (R1), based on the use of generic models (R2) and interfaces (R3)see Figure2.…”
