Re: MC-21 Development Thread

Is there any sign of the PD-14M geared enging coming down the trail yet? The Russian engine makers have been pretty good with gearboxes in the past thanks to their high power turboprops. Unfortunately, no. There is no sign of PD-14M. There was no occurrence in any public available sources about tes...

New aircraft type designed to compete with the 737/A320 rolls out, and not much interest on a.net . An airline announces a new route, or picks up a few more gates - threads blows up.

Re: MC-21 Development Thread

The engine choice of pw or pd is up to the customer? For customers outside Russian or US influence - Yes, sure. For others - I think yes too, but people in Russia would prefer to fly on airlines with PD engines, and leasing companies depends on US, I think, will prefer PW. Btw, to be competitive wi...

Re: MC-21 Development Thread

You forgot to mention that PD-14 has less diameter size 1.9 comparing to 2.1 of PW1400G, so it has less weight and less drag. PD-14 weight: 3780kg P Dear mirosas , according UEC website basic PD-14 has dry engine weight 2870 kg. Please find below reference http://www.avid.ru/en/pd14/ From which sou...

Re: MC-21 Development Thread

I do wonder how efficient the PD-14 will be and if it is going to stack up against the PW1400G-JM. I guess it has 13% less fuel consumption than CFM56, but 3% more than PW1400G or LEAP-X. PD-14 does not use gearbox like PW1000g, and it does not use extremely high temperatures like LEAP-X - the rusu...

Re: MC-21 To Roll Out On June 8

BTW the MS21-200 test airframes will use the PD-14 and not the P&W GTF. Any idea why the MS21-300 uses the PW1400G engine instead of the PD-14? KarelXWB , PD-14 was undergoing on second phase of flight tests mounted on Il-76 LL (Flying Lab). On 25-th of May second phase of testing was completed...
