ADL Version 1.9

Aircraft Dynamics Library 1.9 is part of Modelon���s 2023.2 release.

New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers.


  • Added example model of a Cessna 172 Skyhawk with 3DOF aerodynamic coefficients and a propeller-driven propulsion.
  • Added frame transformation blocks with one partial (interface) class that can be replaced with different classes for transforming e.g., body frame to wind.
    • The SpecifyRotation block now inherits from the partial class, all other functionality remaining.

Breaking changes

  • AircraftDynamics.Utilities.Sliders.Interactive is removed due to Modelica tool incompatibilities.
