NASA hopes to cut back airline fuel emissions with a bug-repellant coating

Bugs splattered across the surface of a commercial jet might seem pretty insignificant, but NASA researchers say they can decrease fuel efficiency by as much as six percent. When those dead bugs collect on aerodynamically-sensitive elements like the leading edge of wings, they disturb the airflow over the surface. That causes turbulent air and drag […]
