The GEnx-1B, GE's next generation turbofan engine on the Dreamliner, undergoes a hail test at Site 4D on the Peebles test site in Ohio as part of the initial certification effort. Ice accretion testing was conducted at Mirabel Icing Facility in Montreal, Canada, where tests simulated the sort of sever icing conditions in which slabs of ice would form in the inlet cowl and engine face after a two-minute delay in activating anti-icing systems.
