Abstract: Abstract The purpose of the project HELISIM, now under the auspices of Gauss Centre for Supercomputing (GCS), is the extension of high-fidelity aerodynamic, aeroelastic and aeroacoustic simulations of rotors and helicopters, both in model and full-scale configurations. Since the flow solver and the overall tool chain have reached a high level of maturity, algorithmic developments are no more the key focus of our projects, but occur as project and application requirements emerge. The helicopter & aeroacoustics group at IAG likewise concentrates on gaining physical insight, reducing risks in unconventional flight states and optimizing the aircraft itself in form of high-fidelity CFD simulations of most complex configurations. Simultaneously, accuracy, robustness and performance enhancements of the flow solver and the tool chain are always part of the work. All in all, the endeavor is to push the physical comprehension and the design and development of rotorcraft further.
