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, ...

Any student new to the principles of fluid dynamics will be familiar with Bernoulli’s principle and the Venturi effect, where the speed of a liquid or gas increases when the size of the conduit it ...

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 ...

The pan-European Neva Aerospace consortium, which is developing heavy-duty drones, industrial and commercial unmanned aerial systems (UAS) and vehicles (UAV) based on its patented distributed thrust ...

A Denver-based start-up has raised $10 million in equity “crowdfunding” to help develop a ducted-fan powered, fixed-wing business aircraft called the TriFan 600. XTI began a crowdfunding campaign on ...

A Norwegian start-up is hoping its small electric-powered ducted-fan engine for unmanned air vehicles (UAVs) can spearhead a move up the weight class into commercial aviation applications.

The computer servers that fill huge data centers are producing more heat with every new generation of processors. It’s a problem that’s sending engineers on a search for cooling fans that are both ...

As a proposed alternative to heavy vehicle road transport, UK-based 4x4 Aviation has conceived a hybrid VTOL cargo plane fitted with electric, tiltable, ducted fans that it claims will be able to ...

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 ...
