GE, Navy team to reduce Super Hornet specific fuel consumption

  • 09-Apr-2010 05:54 EDT

The U.S. Navy has an active fleet of more than 400 Super Hornets, plus 21 EA-18G Growler electronic-attack aircraft. The F414 engine for the F/A-18E/F and EA-18G is rated at 22,000 lb thrust and is in the 9:1 thrust-to-weight ratio class.

GE Aviation is teaming with the U.S. Navy to develop and adopt technologies aimed at reducing the specific fuel consumption (SFC) for the Navy's twin-engine F/A-18E/F Super Hornet fleet. The F414-GE-400 engine powers the F/A-18E/F and E/A-18G aircraft. Under this program, GE Aviation is manufacturing a single engine to demonstrate the fuel-saving technologies and will conduct engine testing to quantify the amount of fuel savings for the technologies in combination as well as individually. Advanced engine components that will be demonstrated include an advanced six-stage compressor, a high-pressure turbine featuring advanced air cooling, new-design low-pressure turbine blades, a performance-seeking control, and afterburner exhaust nozzle area optimization. Incorporation of SFC improvement technologies in the Navy's F414 engine could result in annual fuel savings of nearly 2 million gal.
