A new study reveals how noise is generated and propagated from these engines, technically known as boundary layer ingesting (BLI) ducted fans. The mystery of how futuristic aircraft embedded engines, ...

Whisper Aero doesn't plan to actually make the Whisper Jet, but this vision shows how 11 small ducted fans could be mounted on each wing. The jet engines on commercial airplanes can be absolutely huge ...

Ducted fans have emerged as a promising propulsion solution for modern Unmanned Aerial Vehicles (UAVs), particularly in applications that demand high safety, efficiency and low noise levels. Enclosing ...

Thinking about it, thrust is generated by pressure...Like a filled balloon has pressure (kind of a potential energy) and when you release the stem the pressure is released, thrust is generated, and it ...

Distributed ducted propellers show immense potential for low-altitude aircraft, but the vast number of possible designs complicates standardized analysis. This research introduces a novel equivalent ...

The mystery of how futuristic aircraft embedded engines, featuring an energy-conserving arrangement, make noise has been solved by researchers at the University of Bristol. The study, published today ...
