NASA Hosts Green Aviation Summit

The Green Aviation Summit is highlighting NASA's work to develop aviation technologies that are designed to make air transportation cleaner and quieter for the environment.

Examples of green technology NASA has developed in the past include winglets and chevrons. Winglets are the vertical attachments that can be seen on the wing tips of many commercial airliners in service today, and are designed to reduce fuel consumption. Chevrons are the scalloped edges on the engine nozzles of some models of commercial and cargo aircraft just now entering the market, and are designed to reduce noise.

NASA has a suite of incremental goals for demonstrating the feasibility of aircraft technology and air traffic management techniques that can minimize the environmental effects of air transportation by:

-- Enabling aircraft to burn 33 percent less fuel than today's most efficient models by 2015, 50 percent less by 2020, and better than 50 percent less by 2025.

-- Cutting engine emissions of nitric oxide and nitrogen oxide, which contribute to ozone creation, 20 percent by 2015, 50 percent by 2020, and better than 50 percent by 2025 -- when compared with today's best engines. Reducing the amount of fuel burned reduces emissions of carbon dioxide, which contribute to global warming.

-- Reducing the nuisance noise footprint around airports to one-third its current size by 2015 and one-sixth by 2020, and containing it within the airport property boundary by 2025.

NASA aims to facilitate the transition of new capabilities to manufacturers, then to airlines and ultimately to the Federal Aviation Administration, for the ultimate benefit of the flying public.

The NASA administrator said it is crucial for the agency and its stakeholders to collaborate closely to that its aeronautics research continues to be both relevant to the aviation community and beneficial to the flying public.

"Just as I like to tell the scientists and engineers who send our human and robotic missions out into the cosmos, you are contributing to national goals and helping people in the work you do every day," Bolden said. "We are going to make measured progress leading to ever expanding accomplishments to meet the myriad increasing challenges. This is our challenge - to shape the future in aeronautics."

Portions of the Green Aviation Summit are being broadcast live on NASA Television's Education Channel.
