Well not quite. In the geared turbofan the fan is still part of the engine itself where in this one we're looking at you've got seperate propeller/fan things attached to a turboshaft then enclosed in a shroud. I'd call it an ultra-high bypass ratio engine but it's not really that either. ??? CRISP here is generally what is considered a UHB. Ducted propeller? Ducted turboprop?
Conceptually it is probably closest to CRISP. Unlike P&W's geared fan the NK-93 has two counter-rotating 'fan' stages, the first with 10 blades and the second with 8. It's interesting that the blades have such a narrow chord though, thanks flateric!
Most of the online literature describe it as a ducted propfan. I believe it's similar to SNECMA ducted contra-rotating propfan (http://www.flightglobal.com/news/articles/picture-snecma-future-engine-concept-revealed-213520/). I'm quite interested in the technical literature/papers and conference papers on this engine but a google search (in google translated Russian/Ukrainian) revealed nothing. Hoping forum members can help out. Thanks in advance!
