The FAA awarded five contracts worth a total of $125 million over five years to engine manufacturers and Boeing to “develop and demonstrate technologies that will reduce commercial jet fuel consumption, emissions and noise.” The research is intended to accelerate introduction of green technology in the FAA’s Next Generation air traffic modernization program as part of the agency’s continuous lower energy, emissions and noise (Cleen) program. Participants include Boeing, General Electric, Honeywell, Pratt & Whitney and Rolls-Royce North America, all of which will match the FAA’s investment in the cost-sharing program. The companies will study alternative fuels, lighter turbine engine components, noise-reducing engine nozzles, wing trailing edge technology, optimized flight trajectories and open-rotor and geared turbofans.
Goals of the Cleen program include:
