AL-31fm2 have a new low pressure compressor (KND-924-4), the inlet diameter is 924 mm
117S have another new low pressure compressor, the inlet diameter is 932 mm
they are not the same engine.(Although I fodder that this parallel development is a waste of resources)

Is the AL-31F-M3 the same engine as the 117 on Pak-Fa:confused:
And is the AL-31F-M2 the same as the 117S engine, both having 14.500kgf:confused:
no, products “similar” of different companies but based on the same point of beginning (AL-31F)

Have Solyut and Saturn shared all the basic consept & design in order to have a more standardization on all the engines they produce?
w.t.f. is going on??
I believe that no, but both comañian supposedly cooperated to produce the definitive motor of the PAK-FA
news about ” Al-31FM2″:)
This may be a bit off topic, but why has no one bought a license to build Fulcrums? Is it because MiG was not as willing to make the kind of deal Sukhoi did?
I think that in the book by Yefim Gordon said that North Korea bought the license in the 80
That is one of the 4 serials delivered late last year.
Do you know when it happened?
Apart from these 12, how many Su-27 were upgraded to SM standard from existing airframes so far? Any UBs included?
48 Su-27Sm in 4 Squadron + some units in Lipetsk, etc.
And how many MiG-29 SMT refused by Algeria are in RuAF service?
Thanks.
30 SMT and 6 UBT
maybe wiskypedia is not the most reliable source.
AL31 FP, Single Crystal Blade done by Investment casting at HAL in a vacuum furnace. And I believe AL55 also have a single crystal blade..
and NK86A? I think it was the first soviet engine with monocrystal blades, I am not sure about NK-32.
Sorry to revive a theat so old. But I think it would be interesting to update the info.
Which Russian/Soviet engine in mass production using single crystal blades?
NK-86A?
NK-32?
PS-90A2?
VK-2500?
AL-31F serie 4?
AL-31FP?
Al-31FM-1
RD-33MK?
AL55?
thanks for you answer.
It is difficult my to find the servicelife and MTBO of French motors. for example ATAR-9 and M53. Is similar its MTBO to contemporary American engines?
Thanks
Another point important to compare is TMBO and service life, I believe that the RB199 loses in these parameters. How are compared the French motors with respect to the Americans in MTBO and service life? for example J-79 versus ATAR-9
The Argentine military spending is near the 0,7% of argentinean GDP. The probability of an attack to the islands is 0%.
Otaku:
You known which is the model of HUD in Su-34?
Good question.
Dunno, but that is the older cockpit layout i believe.
Do they have the same Hud now as they did back then?

I think that is the same HUD and is the same as the Su-25SM
New HUD (ILS-2)
Do you have more info for this element?
