Simulation Tool for Analyzing Complex Shape-Changing Mechanisms in Aircraft

This paper describes the development of a simulation tool to study the time domain, in-flight behavior of aircraft morphing mechanisms. Limitations of existing tools are discussed leading to requirements for the new capability. The framework of the tool is discussed as well as the component analyses including control systems, aerodynamics, modal structural representations, and multibody kinematics. The basic capability of the tool is demonstrated through example simulations of a folding morphing wing.
