Video: DLR Institute of Aerodynamics and Flow Technology - 'Dancing' helicopter helps reduce noise
Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) in Göttingen have visualised the main cause of noise from a heavyweight helicopter in flight. To do this, they conducted flight tests with a CH-53G of the German Armed Forces by letting the helicopter 'dance' close to the ground.
