When you picture a propeller-driven aircraft, you probably imagine a single engine plane with the propeller spinning at the front. There's a good reason for that, as the front-facing design has proven ...

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 ...

If you have ever observed a propeller plane closely, you might have noticed the propeller is slightly angled to the right. The angled engine and propeller can seem jarring, considering symmetry is ...

The high-efficiency aerodynamic and aeroacoustic optimization framework comprises the following key modules: 1) Shape parameterization, which transforms the baseline geometry into a set of design ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental ...

Europe has recently voiced very high ambitions for reducing Aircraft community noise, with the Advisory Council for Aviation Research and Innovation in Europe (ACARE) pushing for a 65% noise reduction ...

Could the secret to transforming propeller design lie in the dimples of a golf ball? It might sound far-fetched, but the same aerodynamic principles that allow a golf ball to soar farther and faster ...

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 ...
