The Aircraft Dynamics Library by Modelon is a Modelica library for designing and analyzing aircraft and their subsystems, featuring advanced sizing and synthesis methods. It includes graphical model building, robust wing sizing, and compatibility with other aerospace libraries, making it suitable for performance evaluation and design validation. The latest release, 2019.2, enhances simulation capabilities, allowing users to simulate intercontinental flight trajectories and access important variables easily.

- 9. WING SIZING Douglas DC-9 aircraft rigged to a test bench with key scalar variables used to define the geometry. This focus is to only change scalars that define the wing's geometry and observe the effect on the entire aircraft. Changing one of the scalar values, the other scalars are adjusted based on a set of equations in the component. The wing's mass changes with geometry. 9©2019 Modelon Example: Typical wing input parameters and classic geometry relations
- 10. LANDING MANEUVER This example demonstrates the contact between wheels and the runway. Applying the brakes will affect airframe posture and load on the wheels. The aircraft system including landing systems is interesting for several analyses, such as behavior evaluation, controls validation, and system design decisions. 11©2019 Modelon
