Aircraft that can fly into hurricanes are technologically equipped, but still rely on classic propellers, or turboprops, to ...

A contra-rotating propeller system uses two propellers spinning in opposite directions. This impressive feat of engineering changed the course of aviation.

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 ...
