Fuel consumption and greenhouse gas emissions are huge priorities in the aviation industry – passenger airliners chew through amazing quantities of fuel. Take the Boeing 747, which guzzles somewhere ...

A flight test investigation has been conducted to determine the performance of wingtip vortex turbines and their effect on aircraft performance. The turbines were designed to recover part of the large ...

Winglets reduce wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplane's wing and that on the lower surface. High pressure on the lower ...

Like the way birds curl their wingtip feathers upward, airplanes can fly more efficiently with these winglets. This saves fuel and reduces CO2. Forty-four years ago this July, NASA began testing a ...
