Coupling Mid-Fidelity Aerodynamics and Multibody Dynamics for the Aeroelastic Analysis of Rotary-Wing Vehicles

A mid-fidelity aerodynamic solver based on the vortex particle method for wake modeling, DUST, is coupled through partitioned multi-physics coupling library preCICE to a multibody dynamics code, MBDyn, improve accuracy of aeroelastic numerical analysis performed rotary-wing vehicles. In this paper, tool firstly validated by solving simple fixed-wing and problems from open literature. The transient roll maneuver complete tiltrotor aircraft then simulated, show capability analyze aeroelasticity complex rotorcraft configurations. Simulation results importance accurate representation rotary wing aerodynamics provided loads evaluation, stability assessment, maneuvers configurations characterized interactional aerodynamics. limited computational effort required approach represents an effective trade-off in obtaining fast solutions that can be used preliminary design novel vehicle
