Without the aerodynamic forces of lift and drag, aircraft would be unable to fly, wind turbines would not spin, and countless other machines that we depend on every day would not work. What, exactly, ...

For a better understanding of aerodynamic testing, we asked an expert to provide us with some basic, but valuable information on the subject. The author is directly involved in using his knowledge of ...

Researchers at Stanford University have discovered counterintuitive ways that birds use drag and lift when they fly. The findings may influence future research into how to “repurpose” drag and lift in ...
