Aeroacoustics and active flow control are closely intertwined fields that focus on reducing noise and improving aerodynamic performance. Aeroacoustics studies the generation, propagation, and control of sound caused by airflow over surfaces, particularly in rotorcraft, aircraft, and other air vehicles. This includes understanding the noise generated by complex aerodynamic phenomena like turbulence, vortex shedding, and flow separation. Active flow control involves using dynamic techniques, such as surface actuators or external forcing, to manipulate airflow and mitigate undesired aerodynamic effects, including noise and drag. By actively controlling flow, engineers can reduce noise emissions, enhance stability, and improve overall efficiency. In the context of rotorcraft and urban air mobility systems, the integration of active flow control techniques has the potential to create quieter, more efficient vehicles. Combining these fields provides a promising approach to address noise challenges while optimizing aerodynamic performance in modern aerospace applications.

The goal of combining aeroacoustics and active flow control is to develop innovative solutions that reduce noise pollution and enhance aerodynamic performance in aerospace vehicles. By understanding the sources and behavior of aerodynamic noise, particularly in rotorcraft and urban air mobility systems, the aim is to design quieter, more efficient vehicles. Active flow control techniques can be employed to manage airflow, reduce drag, and suppress turbulence, leading to improved fuel efficiency, stability, and operational capabilities. Ultimately, the goal is to advance aerospace technology to create environmentally friendly, high-performance vehicles that meet the growing demand for quiet, sustainable air transport in urban environments.

The "Aeroacoustics and Active Flow Control" topic invites contributions that address the intersection of noise reduction and aerodynamic performance optimization in aerospace vehicles.
