Winging it

We’ve just kicked off a new round of ecoDemonstrator program testing with three significant environmental technologies on board our ecoDemonstrator 757. The airplane made two initial test flights earlier this week from Boeing Field in Seattle, looking at ways to improve efficiency and to reduce noise and carbon emissions.

For this round of testing, we’re collaborating with TUI Group and NASA. And you could say we’re “winging it” this time.

On the left wing, we’ll be evaluating technologies to reduce environmental effects on natural laminar flow - smooth airflow over the wing - as a way to improve aerodynamic efficiency. As an example, the ecoDemonstrator 757 will test a Krueger shield that can protect the leading edge from insects.

And on the right wing, Boeing and NASA will test bug-phobic coatings to reduce the residue left by bug strikes on the leading edges of aircraft wings, also to reduce drag.

On the vertical tail, Boeing and NASA are testing active flow control to improve airflow over the rudder and maximize its aerodynamic efficiency. Based on wind-tunnel testing, active flow control could improve the rudder’s efficiency by up to 20 percent and may allow for a smaller vertical tail design in the future.

Except for Boeing’s proprietary technology, NASA knowledge gained in ecoDemonstrator collaboration will be publicly available to benefit the industry.

And just to prove how serious we are about our environmental commitment, we’ll recycle this 757 at the end of its flight tests using environmental best practices. That’s what I call going green—from start to finish!

Will this 757 be in service for a while with TUI or is it's passenger hauling time over? It's a sad story to think such a good looking aircraft is about to be destroyed.

Andrew Boydston (Boise, ID USA):

Thank you Randy, I love it! A Winging It recognition is priceless from you and Boeing. You Go Boeing and build it best! ;)

Dr Dorothy (MA USA):

Congratulations to Boeing 787 ecoDemonstrator and TUI Group which together with the efforts of our NASA and Pentagon/USAF maintaining the good environment as well as the good ecology contributing to the grand harvest of farmers and fishermen in our USA where just corn production is at 14.4 billion bushels and area for just corn harvest in the United States is at a record 84.1 million acres!

Best regards,
Dr Dorothy

Norman Garza (Long Beach, CA):

Before reading the title of the article, I though for a millisecond or two that Boeing was thinking of finding a range and capacity replacement for the 757. Obviously the debate on a 757 replacement has heated up to a feverish pitch by the armchair generals and CEOs of the airline and aviation world.

The 757s are getting old but at least this one burns clean like the newer aircraft in competes with.It is good that companies care about the environment and fuel consumption and exceeding the environmental rules of government agencies.

Cristiano Arruda:

Please don't destroy it after the tests, give it to me. Be sure that Boeing will be clustering a new client.
