GEnx-2B engine begins icing certification testing

The GEnx-2B engine for the Boeing 747-8 aircraft has started its final certification test, the icing test, at GE’s Mirabel, Quebec icing facility. In January, the GEnx-2B engine completed its second round of flight tests aboard GE’s 747 flying testbed and has racked up a total of 53 flights and 275 flight hours. The results of the GEnx-2B engine’s emission testing that was completed late last year confirmed GE’s expectation of its innovative twin annular pre-mixing swirler, TAPS, combustor with NOx emissions as much as 60% t below today’s regulatory limits and other regulated gases as much as 90%.
