The propeller — a relic from the dawn of powered flight more than a century ago — is making a comeback as an emblem of aviation’s greener future. Rotors are proliferating on futuristic air taxis and ...

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 ...

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 ...

Hartzell’s 5-blade composite propeller reduces aircraft weight by around 20 pounds total by using carbon fiber construction ...

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 ...
