At the very crux of engineering is the desire to problem-solve, optimize, and squeeze out every bit of efficiency possible from the system being built. Aircraft design and aeronautical engineering ...

Subscribe to our newsletter for the latest sci-tech news updates. SINTEF has now designed and manufactured new measuring equipment for model testing of contra-rotating propellers. This could be good ...

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 ...

Sharrow's extraordinary looped propellers were already some 30% more efficient than traditional designs – and now the company has put two of them together into a coaxial, contra-rotating prop that ...

It’s a rare occasion when a piece of engineering transcends its pure industrial function and becomes art. And it’s even rarer when that metamorphosis is the byproduct of a quest for better performance ...

The Russian Tu-95 'Bear' isn't just a relic of the Cold War, with the potential for a nuclear payload capable of untold devastation. It's eight contra-rotating propellers also enable to it hold the ...
