BirdSim and FlapSim
flapping wing flight tools:

BirdSim beta version

FlapSim V1.2

These tools can be used to simulate flapping wing flight dynamics of birds, insects, and other animals that fly.

The models are based on previous research that I did here. 

Feel free to download, have a play, and let me know if there are any new features you would like added in the future.

  • Note that they each App requires a version of the Matlab Compiler Runtime, which can be downloaded free from the links given in the ReadMe files.

  • While my Apps are light, The Matlab Compiler Runtimes are unfortunately pretty big downloads, sorry about that!

flight dynamics model:


AircraftDynamics V1.02

AircraftDynamics is a modular flight dynamics simulator design as an introductory tool for this interested in learning about the dynamics of fixed-wing flying vehicles. It is highlgy flexible, in being able to model aircraft of all shapes and sizes. It uses a very low order aerodynamics method, which can also be adjusted to suit the users needs.


AircraftDynamics requires Matlab, Simulink and Simscape multibody toolbox to run. This verison is built in Matlab 2023b, but older versions can be made available by request.
