Keywords: rotorcraft aerodynamics, rotorcraft aeroacoustics, and vortex particle methods

The initial development of a combined active aeroelastic aeroacoustic rotorcraft code is presented. A discussion of the theory behind the aerodynamic component - the GENeral Unsteady Vortex Particle code (GENUVP) - is presented. The implementation of a new aeroacoustic component is summarized. Results from the current work, including aerodynamic modelling of the NASA/ARMY/MIT Active Twist Rotor (ATR) and aeroacoustic modelling of a scale UH1H rotor, are presented.
