Aren't we talking about geared turbofans, as described in the article and http://en.wikipedia.org/wiki/Geared_turbofan http://en.wikipedia.org/wiki/Geared_turbofan ? Geared turbofans, unlike the ungeared GEnx, presumably have gears in gearboxes.
- hollerith 13y agoThe person I replied to implied that all turbofan engines have gearboxes, that gearing was necessary to have the fan rotate at a slower speed than the "main engine". In reality, the vast majority of the turbofan engines currently used in commercial aviation do not have gearboxes. The engines referred to in the wikipedia article you cite are still in development or just entering production.
