NEWTOWN, Conn. - GE's new GE9X turbofans will have new design composite fan blades. The company has designed a thinner and stronger blade using carbon fiber and epoxy resin for weight savings, with a steel alloy leading edge. The GE9X's fan diameter has grown over that of the GE90 to 133 inches comprised of 16 blades. GE plans the first full core test in 2015 and the first complete engine going to test the following year. Flight testing is expected to begin in 2017 with certification and service entry following in 2018.
