>Depending on how you count, there are just two to four builders of large commercial aircraft (Airbus, Boeing, Embraer, and now COMAC).

Where is Russian Sukhoi?

Re:Why it's so hard to build a jet engine by D_Alex on Saturday March 01, 2025 @05:11AM (#43217831)
It is part of UAC, along with Ilyushin and Yakovlev.

Still not in the list)
Re:Why it's so hard to build a jet engine by D_Alex on Saturday March 01, 2025 @05:22AM (#43217898)
Yes, and they are ahead of COMAC in the number of aircraft produced.

It will be interesting to see if UAC emerges as a serious competitor to Boeing and Airbus (and COMAC) in the near future.

Seems unlikely. They had their window of opportunity when they had an active Western marketing arm, Russia wasn't a sanctioned nation, COMAC was barely getting started and the early reports of the Superjet were quite positive. Suffice to say the airlines that passed on the opportunity aren't regretting it and the couple that bought them did regret it.

Probably the sanctions will be greatly reduced or eliminated this year or next, and the sanctions are great marketing to other countries that fear being sanctioned—which, following Vance's speech in Munich, probably should include Romania, Germany, Sweden, Denmark, and maybe even the UK.
Re:Why it's so hard to build a jet engine by notahacker on Saturday March 01, 2025 @08:21AM (#43218981)
I don't think Swedes and Brits are particularly worried about being unable to obtain parts and maintenance for Boeing aircraft, never mind Airbus...

Even Iran is flying old Western aircraft

Last year Ukraine wasn't particularly worried the US would cut off military aid, Romania wasn't particularly worried the US would paint it as a poster child of failed democracies, and Denmark wasn't particularly worried the US would annex Greenland. The world is unpredictable.

Nah, Ukraine knew Trump had an excellent chance of winning and was likely to cut off military aid, and the rest of the world was well aware that a Trump return would mean more moronic threats and trash talking.

Trust me, we're not rushing out to buy shitty Russian aircraft as a hedge.

Re:Why it's so hard to build a jet engine by D_Alex on Saturday March 01, 2025 @07:18AM (#43218528)
I disagree with you about the effect of sanctions. Their result was that airliners became a strategic priority rather than something Russia was happy to buy overseas forever.

Furthermore, the sanctions demonstrated that there is sovereign risk associated with purchasing Western airliners.

Finally, IIRC the airline's regrets were largely related to the poor early reliability of the French-built parts, specifically combustors, for the Superjet engines. It remains to be seen how the new Russian engines will perform.

Re:Why it's so hard to build a jet engine by notahacker on Saturday March 01, 2025 @08:06AM (#43218874)
Demand for Russian built airlines in Russia /= them being competitive with Boeing and Airbus. The USSR built airliners as a strategic priority for the domestic market for decades: their track record of being terrible was one of the reasons behind scepticism of the Superjet

And airlines in most countries have far more to worry about buying aircraft whose maintenance depends on a faraway pariah state and that are not certified in Europe than they do about US sanctions targeting them. And even if they do, still not necessarily more difficult to circumvent the sanctions (as Mahan Air did with wet leased 747s) and access a worldwide parts supply and MRO market than rely on being able to maintain and sell on your Russian aircraft at reasonable price and timeliness...

It would also be surprising if the new Russian engines were competitive on performance with new Western engines, and likewise with other components they've had to switch to domestic manufacture for.

Re:Why it's so hard to build a jet engine by drysine on Saturday March 01, 2025 @09:39AM (#43219618)
>faraway pariah state

By that you mean a state sanctioned by the US and the EU, which together comprise about 10% of the world's population.

Re:Why it's so hard to build a jet engine by notahacker on Saturday March 01, 2025 @10:01AM (#43219867)
And most of the companies that'll get parts shipped to you and do your maintenance, especially when you consider getting UAC MRO certifications isn't exactly an exciting opportunity for companies from China, the Middle East or Latin America either. And doing business with Russian aerospace companies was a PITA when you had access to easy international payments and didn't have a risk of becoming a sanctioned company yourself
Re:Why it's so hard to build a jet engine by nradov on Saturday March 01, 2025 @01:34PM (#43222128)
The sanctions have almost entirely shut down Russian airliner production. They have only managed to deliver a handful of complete aircraft since 2022, and those largely used parts already on hand. Much of their supply chain is just gone and will take years to rebuild. When they eventually do get the complete production system up and running again their engines will still be less fuel efficient: airlines live and die by fuel efficiency.
Re:Why it's so hard to build a jet engine by throwaind29k on Saturday March 01, 2025 @09:56AM (#43219796)
They have the MC-21 under development as well, though not much information seems available.
Re:Why it's so hard to build a jet engine by drysine on Saturday March 01, 2025 @10:37AM (#43220274)
They are producing MC-21 without engines waiting for the PD-14 to be ready. We will see in a couple of months if the engine's problems have been solved.
Re:Why it's so hard to build a jet engine by drysine on Saturday March 01, 2025 @05:26AM (#43217928)
Yeah, waiting to see if the current iteration of PD-14 engine[0] is finally up to the task. Two years ago UAC tested them and found to be in the need of improvement.

Re:Why it's so hard to build a jet engine by D_Alex on Saturday March 01, 2025 @07:01AM (#43218433)
Yep... it is hard to build a competitive jet engine.

If the Russians manage to do this, it would be another example of the stupidity of the sanctions.

I bet COMAC is cheering them on too.

Bombardier until recently was another, although it was taken over (?) by Airbus.
Re:Why it's so hard to build a jet engine by dredmorbius on Saturday March 01, 2025 @09:18AM (#43219441)
Huh, I'd not heard that.

The Wikipedia page on Bombardier is ... not especially clear about present ownership, though apparently debt incurred developing the CSeries (Airbus 220) aircraft lead to spin-outs of much of the core business, including large shares (50% and then another acquisition) of CSeries ops by Airbus.

<https://en.wikipedia.org/wiki/Bombardier_Inc.>

The top of the article seems to portray Bombardier as an independent company, other bits not so much.

Re:Why it's so hard to build a jet engine by Cyph0n on Saturday March 01, 2025 @10:10AM (#43219981)
My recollection is that Boeing essentially had insane tariffs applied on US imports of Bombardier commercial aircraft after Delta made a large order & was preparing for delivery.

Shortly thereafter, Airbus came in and acquired a controlling stake of Bombardier Aviation, took over the CS planes, and agreed to manufacture them in the US (Airbus manufacturing is in the EU).

The way it played out seemed to me as if Boeing and Airbus conspired to kill off a viable competitor after they saw how well received the CS100 and CS300 were.

This is all on top of the overall financial troubles the company was facing.

I could be entirely off the mark, so I will let those more knowledgeable chime in from here.

Re:Why it's so hard to build a jet engine by dredmorbius on Saturday March 01, 2025 @11:28AM (#43220896)
I like your take, FWIW.
Re:Why it's so hard to build a jet engine by samat on Saturday March 01, 2025 @06:12PM (#43224990)
CS300 are the best aircraft I have ever flown in. A lot of room, very good air inside, very nice design aesthetic.
Re:Why it's so hard to build a jet engine by ianburrell on Saturday March 01, 2025 @01:36PM (#43222155)
Bombardier makes only private jets now. The C-series was sold to Airbus and is now the 220.. Q-Series turboprops were sold to De Havilland. The CRJ-series regional jets were sold to Mitsubishi.

De Havilland was owned by Bombardier, but Viking Air bought De Havilland's designs and Dash 8, and renamed the holding company De Havilland.

Re:Why it's so hard to build a jet engine by drysine on Saturday March 01, 2025 @09:36AM (#43219595)
Looks like they only kept the business jet division, selling the rest to different buyers including Airbus. [0]
