Abstract
Comprehensive aeromechanics simulation for rotorcraft is a complex field involving models from different disciplines with very different structure and complexity. VAST (Versatile Aeromechanics Simulation Tool) addresses this field with a new approach involving a generic coupling of state-space models. The paper describes the approach and focuses on aerodynamic and structural methods used in the framework. The implemented models for aerodynamics include unsteady aerodynamics based on a semi-empirical analytical model for the blade sectional airloads and a vortex-lattice model for the computation of the rotor wake. The structural modeling is based on a generic multi-body approach.
