REAL-TIME MULTIBODY ANALYSIS OF WIND-TUNNEL ROTORCRAFT MODELS FOR VIRTUAL EXPERIMENT PURPOSES

This work is focused on the implementation of a general multibody analysis framework for the real-time simulation of complex systems. It is applied to the modeling of the Semi-Articulated Soft-InPlane (SASIP) rotor recently installed and tested on the Wing and Rotor Aeroelastic Testing System (WRATS) at NASA Langley. The aim is to obtain a detailed, yet efficient virtual experiment, based on state of the art multibody analysis capabilities and low cost, off the shelf hardware, to predict the behavior of an aeroelastic rotor model and its interaction with a real wind-tunnel experimental setup.
