Winglets Save Billions of Dollars in Fuel Costs

Originating Technology/NASA Contribution

Anyone who has made a paper airplane knows that folding the wingtips upward makes your plane look better and fly farther, though the reasons for the latter might be a mystery. The next time you snag a window seat on an airline flight, check out the...

Sensor Systems Collect Critical Aerodynamics Data

Originating Technology/NASA Contribution

The next time you blow out a candle, watch how the smoke behaves. You will see that it rises first in an even stream. At a certain point, that stream begins to break up into swirls and eddies as the smoke disperses.

Coatings Extend Life of Engines and Infrastructure

Originating Technology/NASA Contribution

Every time a jet engine is started, it goes through a thermal cycle of extreme temperatures, reaching as high as 2,700 °F within the engine’s combustor. Over time, the expansion and contraction of engine parts caused by this cycle lead to...
