Rotor aeromechanics is a multidisciplinary branch in the
field of rotorcraft that involves performance, loads,
vibrations, stability, and noise. Aeromechanic analysis
in this field is a complex task typically requiring
specialized software tools to simultaneously resolve the
coupled structural, mechanical, and aerodynamic
solutions that contain motion (both rigid and elastic) and
forces. One drawback of these tools is that they are often
overspecialized and do not lend themselves well to the
analysis of the latest rotorcraft advances and concepts,
including those utilizing distributed electric propulsion.
In this paper, a Modelica library is presented that
provides an extensible platform for performing analysis
and design studies of current and future rotorcraft.
Several examples are presented that illustrate how the
library can be used to perform aerodynamic and whirl
flutter stability analysis as well as control system design
for multi-rotor aircraft.
