Pond scum, grass clippings and old T-shirts may not seem to be terribly appetizing topics, but they are providing food for thought as alternative energy sources that can power today\u2019s United States military aircraft and support broader military strategy aimed at fuel independence. GE F414 engines are at the front line, having powered the Boeing F\/A-18 \u201cGreen Hornet\u201d on its initial biofuel-powered flight yesterday — the first Naval fighter to be powered by a biofuel blend. The Navy noted that the F414 engine performed as expected during the 45-minute flight — and indicated \u201cthe aircraft did not know the difference between the bioblend and its traditional fuel source.\u201d<\/p>\n

The flight, pictured above, drew hundreds of onlookers that included Secretary of the Navy Ray Mabus, who has made research, development, and increased use of alternative fuels a priority for the Department of the Navy.

In addition to environmental stewardship, biofuel blends of petroleum and non-petroleum sources can offer significant advantages. Designed to be \u201cdrop in\u201d replacements, their physical and chemical properties are similar, if not identical, to conventional fuels they replace. As a result, customers do not necessarily need to spend time or money making costly aircraft modifications. Applied to today\u2019s aircraft, the \u2018Green Hornet\u2019 initiative can increase capability by reducing reliance on fossil fuels from foreign sources and reducing volatility associated with long fuel supply transport lines.<\/p>\n

In addition to helping the Navy meet its goal of deriving half its energy needs from alternative sources by 2020, the F404\/F414 program is proceeding with an eye on green on several other fronts. New technologies could help reduce specific fuel consumption (SFC) for the Navy\u2019s F\/A-18E\/F Super Hornet fleet by 3 percent and save two million gallons annually \u2013 the equivalent of driving your car around the world about 1,200 times if it got 20 miles to the gallon.<\/p>\n

GE is also developing a noise reduction kit for the F414 using a chevron exhaust nozzle. These nozzles have serrated edges where each \u201clobe\u201d penetrates into or out of the primary flow and generates a secondary flow, significantly reducing jet noise. Testing has shown a 2-3- decibel reduction, which is equivalent to turning off one of the F\/A-18\u2019s two engines.<\/p>\n

I\u2019m glad to be a part of this exciting transformation \u2026 and I may think twice before discarding all of my old concert T-shirts!<\/p>\n

\nPower plants:<\/span> Prior to flight testing, GE ran more than 500 hours of component tests and close to 20 hours of F414 engine testing to validate that the engine would operate successfully using the biofuel blend, which used a fuel derived from the camelina plant — a U.S.-grown, renewable, non-food source. In 2008, Virgin Atlantic flew its GE CF6-powered Boeing 747<\/font><\/a> from London to Amsterdam, becoming the first airline in the world to fly on biofuel. (U.S. Navy photo)<\/div>\n
