title = "Active flow control for the reduction of helicopter aeroacoustics noise; computational studies using LES",
abstract = "The aeroacoustics noise has been one of the main issues associated with the helicopters. One of the main sources of noise in helicopters remains the main rotor disk. The main rotor acoustic noise is more dominant in the slow-speed descent. The helicopter aeroacoustics noise has limited its use in wide range of applications and thus, the mitigation of aeroacoustics noise would enable the helicopter to operate in wider range of applications. The research proposes an active flow control approach for the reduction of the helicopter aeroacoustics noise using the synthetic jets. This research is carried out using computational approach, namely large eddy-simulation (LES). The simulations were performed for a Reynolds number, Re = 0.8x106, based on the NACA0012 airfoil chord and free-stream velocity. The present study shows that the active flow control using synthetic jets is a promising approach in mitigating the helicopter aeroacoustics noise.",
