    Somebody with more insight can probably fill you in on this properly, but the main thing about this plane is that it's all supposed to be pretty much state-of-the-art, with a spanking fresh FBW system, unique composite wings and wingbox (made by AeroComposit using a cutting edge out-of-autoclave technique), modern geared turbofans that match the best in the world and so on and so forth.

    This unlike the Sukhoi SSJ or the Comac C919, that while somewhat competitive (at least the former has found some success here and there) most things about them is "legacy" and not up there with the latest stuff that for example Boeing and Airbus are doing.

    The plane that flew today is powered by Pratt & Whitneys:


    ...which is all good, but if the PD-14 turns out to be what people are hoping for, then it's a major achievement on Russia's part that really adds to the significance of the MS-21, and finally something to boast about that is not military (first time in thirty years or something)...

    The PD-14 has been flying for quite a while on the Il-76LL and the second phase of flight testing was concluded a little while ago with good results from what I hear, so let's keep some fingers crossed.

    MS-21 designer had mentioned in an interview that PD-14 will give MS-21 1 % fuel advantage over PW1400

    I read it has 6500 km range in basic version with higher speed than competitors not.Thegger version will be more. This thing is approaching wide body market.

    I don't think the PD-14 is any better than the PW, at least on the tech side it isn't, with one generation older fan/compressor blades, a simpler design overall and so on. It may at least partially make up for that with its smaller diameter, lesser weight and lesser price, plus its (envisioned) superior serviceability (ease and cost).

    But that's up for debate at a later point, it's impossible to tell at this stage. The main thing is that if it really does live up to its projected specifications, it meets the criteria for being a modern and properly (even internationally) competitive engine for civilian aircraft in this class, despite not being absolutely cutting-edge, and that's a big leap forward from pretty much everything Russia has built in the past and builds at present (the PowerJet doesn't count). On the military side of things, Russia has stayed in the game rather well but its aerospace industry needs diversification of this kind.

    The PD-14 design is obviously a platform to improve upon in the future as well, with for example next-gen composite blades and what not, so there's that angle to consider too. Russian aerospace needs this kind of stuff, it's been stuck in a rut rehashing obsolete tech for far too long.
