6. Aerodynamic Frame Design
Aeroacoustics is driving innovation of modern drone frames. Wind tunnel tests and computer-aided design have produced frames with lowest air resistance and turbulence. During flight, well designed air channels and smooth shapes help to lower wind noise. Sound waves are helped to be trapped and dissipated by the way resonators and acoustic diffusers are integrated into the framework. Complex geometries made possible by advanced manufacturing techniques maximise aerodynamic performance and noise reduction simultaneously. These designs have demonstrated amazing performance in lowering general noise characteristics by up to 25% while raising flying efficiency.
