In September, Boeing Aircraft Company flew the “ecoDemonstrator,” a modified American Airlines 737 aircraft (pictured above), to Washington Reagan National Airport to demonstrate the new technologies that are being developed under FAA’s Continuous Lower Energy, Emissions and Noise Program. CLEEN is a NextGen partnership with industry to develop and demonstrate new energy saving, environmental aircraft technologies, procedures and sustainable alternative jet fuels. The participants in the cost sharing agreement include Boeing, General Electric, Honeywell, Pratt & Whitney, and Rolls Royce North America. The project is assessing possible CLEEN benefits including:

  • sustainable alternative jet fuels;
  • lighter more efficient gas turbine engine components;
  • noise-reducing engine nozzles;
  • advanced wing trailing edges;
  • optimized flight trajectories using onboard flight management systems; and,
  • open rotor and geared turbofan engines.

One of the most promising potentials for advances is Adaptive Trailing-Edges, which may improve fuel-saving aerodynamic efficiency and concomitantly reduce aircraft while landing.

The preliminary data suggests that this “test aircraft” may be economically, operationally and environmentally viable and could reduce aircraft fuel burn up to 2 percent.

This FAA/private industry partnership may produce benefits that could be incorporated in aircraft by 2015 to 2018.
