Modelon’s Aircraft Dynamics Library is a Modelica-based library for the design and simulation of fixed-wing aircraft and their sub-systems. It provides an open and extensible environment for a wide variety of applications including design and assessment of hybrid electric propulsion concepts, the analysis, and simulation of six degrees of freedom flight dynamics, detailed landing gear design and analysis, and other complex aircraft systems.
The library built on Modelica-based standards provides reusable and flexible model architectures with reconfigurable pre-defined templates. The models are multi-purpose to support different use cases within the same modeling framework. This means that a model can be configured to use empirical sizing methods for masses and aerodynamics or detailed aerodynamic coefficient tables from CFD. It can be set up to contain the full six degrees of freedom equations of flight dynamics, simplify them to three degrees of freedom, or focus on flight performance only. Additionally, each sub-system can be represented with a simplified placeholder or a detailed physics-based model. Sub-systems models are assembled into airframe, power and consumer sub-system sets which can be configured and exchanged to structure the model architecture.
Modelon’s Aircraft Dynamics Library has been developed collaboratively with multiple partners and applied internally at Modelon over several years. Starting with the 1.0 release, the library is publicly available as an off-the-shelf solution optimized for a wide variety of applications.
