Over the last year, the commercial and military aviation industry has started to talk a lot about greener aircraft and biofuel to reduce the need for crude oil and produce less pollution. Much of the news focuses on biofuels that reduce the need for traditional petroleum based jet fuel, but there are other technologies at work in the airline industry to make aircraft produce less pollution.

The industry isn't only talking about producing less pollution in the way of hydrocarbons, but in less noise pollution with quieter aircraft. Boeing has announced that American Airlines will be the first company to test a new Boeing 737-800 jet that will use new technology to make it more efficient and produce less noise.

"We are proud to have American Airlines as our launch partner for this new generation of technology that can bolster aviation's role as the most efficient means of global transportation," said Boeing Vice President of Environment and Aviation Policy Billy Glover. "There's no better way to prepare advanced technologies for market entry than flying them and no better choice than the best selling single-aisle airplane of all time -- the Boeing Next-Generation 737."

The American 737-800 will be the first plane to use the new technology including adaptable trailing edge technology that is part of the FAA Continuous Lower Energy Emissions Noise or CLEEN program. The trailing edge tech will reduce noise and emissions in all phases of flight including takeoff, cruise, and landing.

Other CLEEN program tech that will be in the aircraft includes a variable fan nozzle to reduce noise and enable other advanced efficiency tech to be implemented. The aircraft will use a flight trajectory optimization system to pick the most fuel-efficient path to a destination. The aircraft will also has regenerative fuel cells onboard for power that could potentially reduce weight, fuel burn, and CO2 emissions.

"Our ecoDemonstrator flight test program allows us to accelerate promising technologies and move them onto airplane models and into new aircraft design considerations across the industry," said Boeing ecoDemonstrator Program Manager David Akiyama. "It also allows us to verify airplane applicability and identify and eliminate potential integration challenges."

American Airlines will also test a dual isle aircraft that is unnamed at this time. The testing on the other aircraft will start later. The American Airlines 737-800 with the new tech onboard will start operations in 2012.
