GE Honda Aero Engines (Booth No. 1336) is refining the design of its HF118-2 engine. More than 100 engineers are working on the 1,700-pound-thrust turbofan, which still has to find its first application. “We are making it lighter and more efficient,” Gary Leonard, president of the General Electric-Honda joint venture, told EBACE Convention News here at EBACE 2006. The engine is continuing to accumulate test hours on the ground test cell and in flight.
