Buran

Any information as to the version fitted to Buran? Andy Dingley (talk) 18:48, 20 May 2018 (UTC)[reply]

Izdeliye 30 is not an AL-31 variant

The sources, including the ones in this article, all state that the izdeliye 30 engine for the Su-57 is not an AL-31 derivative, but a clean sheet design. The only similarity is that it has the same dimensions and fit as the existing izdeliye 117 engines in order to be interchangeable. While it can be mentioned here, I don't think it should be a section of this article, and should have a dedicated article once more information about it is known.Steve7c8 (talk) 04:53, 13 May 2019 (UTC)[reply]

The article title should be Lyulka AL-31

The AL-31 was developed before Lyulka was consolidated into NPO Saturn at Rybinsk. Per WP naming conventions it should be Lyulka AL-31. Steve7c8 (talk) 02:47, 19 November 2021 (UTC)[reply]

Which naming convention is that? BilCat (talk) 08:22, 19 November 2021 (UTC)[reply]

Perhaps not a convention, but the common practice. For instance, it’s McDonnell Douglas F-15, not Boeing F-15, and so on. Steve7c8 (talk) 16:25, 20 November 2021 (UTC)[reply]

Ok, thanks. It's not a hard and fast rule, and tends to be quite complicated. For example, the Lycoming T55 was just moved to Honeywell T55, the current manufacturer. And the Soviet/Russian engines tend to have multiple manufacturers depending on who merged with what in a given decade. So my basic question is, how long was the AL-31 produced by Lyulka after development before being taken over, and how long has NPO Saturn produced it? There's no timeline information in the article, as it jumps straight into the variants, so I don't know the answer. BilCat (talk) 22:09, 20 November 2021 (UTC)[reply]

NPO Saturn was formed in 2001 after the merging of Lyulka, which was renamed Lyulka-Saturn some time in the 1990s, and Rybinsk Motors. The development of the AL-31 occurred in the early 1980s for the Su-27. As with the Soviet practice of having separate design and manufacturing facilities, Lyulka designed the AL-31 while UMPO and Salyut produced it. Since the breakup of the Soviet Union, Salyut became essentially an independent entity, while UMPO became aligned with Lyulka-Saturn, and there is actually serious disputes between Salyut and Lyulka-Saturn, now NPO Saturn, over royalties and intellectual property. Salyut has developed its own improved AL-31 variants which Saturn considers almost illegal. That’s the gist of it. Steve7c8 (talk) 23:51, 21 November 2021 (UTC)[reply]

About as clear as mud, as are most things Soviet-related! What if we just went with Lyulka-Saturn? That'll cover both. BilCat (talk) 01:30, 22 November 2021 (UTC)[reply]

I think that's a good compromise. According to this article, during the AL-31 development Lyulka was known as the AM Lyulka Scientific Technical Centre of NPO Saturn, so Lyulka-Saturn should be able to succinctly capture that. Steve7c8 (talk) 02:45, 22 November 2021 (UTC)[reply]

Engine wakeprofile

Hi, I was wondering if you could add the thrust profile for idol, dry, wet, with afterburner, and wep. I’ve been looking every where for it and I can’t find it. S.Avionics (talk) 15:50, 22 May 2023 (UTC)[reply]
