Talk:Progress D-436

Ukrainian company

The engine first ran in 1985 and was subsequently certified in 1987 If it was developed and certified in that time this was Soviet company and Soviet development not Ukrainian. — Preceding unsigned comment added by 77.165.173.131 (talk) 18:55, 6 July 2020 (UTC)

Need Picture

It would be great if someone could upload a photo for the engine! SidewinderX (talk) 20:00, 12 August 2009 (UTC)

Nice Job!

Great job on the article, I'm into aircraft myself so if you have any questions or want help with a furture article, give me a shout on my talk page, keep up the good work! --Bismarck43 (talk) 20:17, 12 August 2009 (UTC)

Nice work!

The engine is produced in three locations, by:

(Motor Sich - Zaporizhia, Ukraine) http://www.motorsich.com/eng/products/aircraft/tde

("Salut" MMPP - Moscow, Russia) http://www.salut.ru/ViewTopic.php?Id=666

(UMPO -Ufa, Russia) http://www.umpo.ru/en/Good435_139_112.aspx

The designer has two links, but, at this moment, they are not working:

Aircraft it's flown on

Admittedly, I'm not an expert on Russian commercial aircraft, but according to Wikipedia, as of July 2009, there are 3 An-148s built and 8 Be-200s built. So at the the very least the An-148 isn't the prime application yet. There's also a bunch of Tu-334s on order (I don't know how many are built). That said, my uncertainty about the fates of any of these aircraft is probably the weakest part of this article. If you have recent sources that can clear some of this up, that would be great.SidewinderX (talk) 22:51, 12 August 2009 (UTC)

"TX" and "AI-436T12"

I have seen references to both these engines in different locations which leaves me confident enough to leave them as separate entries, but their similarity in thrust class makes me wonder if they're not the same.... if anyone has any additional information, feel free to contribute it! -SidewinderX (talk) 02:06, 13 August 2009 (UTC)

To add to the confusion the latest issue of Aviation Week (Aug-10-09) refers to a "Progress SPM-21" engine for the MS-21. I haven't found any other reference to an engine named that ANYWHERE, so I'm guessing that that is the same as the AI-436T1T2. I guess. -SidewinderX (talk) 10:37, 13 August 2009 (UTC)

Number of Spools

The article was edited to indicate that it is a 3 spool engine. I *think* that is correct, but the only evidence I have to support that is that the D-36 is 3 spools and the D-436 was built from that. Plus no where I've found states that it's a two spool design. That said, Rgvis, if you have a source for that I would appreciate you posting it in the bibliography, or here in the talk page. - SidewinderX (talk) 21:59, 13 August 2009 (UTC)
