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 ...

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 ...

The lift system constitutes a pivotal technology in the makeup of vertical takeoff and landing aircraft systems. The application of ducted rotors in urban air mobility(UAM) has advantages and is one ...
