So what IS electrification in aviation? It's all about how you manage to propel the airplane forward so the amount of fuel burned is reduced, but still get the desired power during every phase of flightātaxi, takeoff, cruise, landing and taxi again! #EarthDay #EarthDayAtHome

Another way to get more fuel efficiency out of an engine? Change its configuration! Jet engines have become more efficient by changing the amount of air flowing through the engine core vs. flowing around the core through fan blades (aka bypass ratio). #EarthDay #EarthDayAtHome

The Transonic Truss-Braced Wing aircraft, designed to be more aerodynamic and fuel-efficient than current designs, will be used to tackle the challenge of increasing the aerodynamic efficiency of an airplane moving through the air. #EarthDay #EarthDayAtHome

Structurally stronger
Less weight 
Longer lasting
Easier to repair Composite materials have been used in aerospace settings for decades, and should see increased application to develop more efficient, sustainable vehicles. #EarthDay

Why is NASA doing this? 
These efforts are part of NASA Aeronauticsā Strategic Implementation Plan, which was developed through listening to the needs of government agencies, industry, academia and other stakeholders in the future of aviation. #EarthDay #EarthDayAtHome
