Chinese Engine Development

Well, I didn't even mention the year of introduction. I was just answering the objection that the Russification of the Su SSJ 100 and MS 21 or TU 204 took 5 years and that it was too much. Who can do it? We'll see with Chinese projects. New engines for these aircraft are in certification tests. In addition, they can use the existing ones. It is certainly worth noting that the Al 51 engines for the SU 57, etc. are already in serial production with good parameters. Of course, with thrust vectoring. Otherwise, a new line of new and heavily modernized engines for civil aircraft and helicopters is being created. There are already quite a few in production. We can name them. And for the most part, these are original Russian developments. Russia's problem is, of course, capacities. It is a very wide scope and the country has only a tenth of the population of China, but very long experience on which to build. Well, we probably don't need to discuss the deadlines... that is everyone's problem. Unfortunately, the deadlines are usually not set by designers, right? As if we didn't know :) And the war is also worth a little, isn't it.
Well, the discussion about this probably belongs in another thread, isn't it. However, I follow it a little and it's good to get involved sometimes. I have time now, I'm an old man. I've been dealing with the Russians for quite a few years and I know them a little. I have no illusions about them, the occupation in 1968 and my experience with their dealings from a position of strength got me out of that.
China has its foot in this area and the results will surely come soon. I trust it, as a long-time supporter of China. About 70 years. They make me happy, boys and girls. They'll soon be at the top here too.

where you can find a fairly objective view. The boys are critical of each other, aren't they?

Is this a joke?! When was the last time the certification of a new high-end engine took place in Russia

Is the PD-14 high end enough for you?

The project started in 2009 and it got certified in 2018. It took longer than expected because they only caught some issues late in the flight test stage and funding was throttled because of delays in the MC-21 aircraft itself.

and when did this last take place in the announced time?

The Russians are currently finishing certification of the PD-8. If it goes as expected it will be designed in 5 years.

1 year to design the engine, 1 year to build a prototype, 1 year to ground test it, 1 year to flight test it, and 1 year for certification.

This is typical. 5 years if everything goes well and double the time if development is troubled.

Don't get me wrong, but if serious, then look at every modern designed civilian engine and even more, what about the AL-51 announced for years? Nothing...

The PD-14 is in limited serial production, and the PD-8 is in risk production.

As for the AL-51 from I understand the engine core is finished, if you see any additional delays it will be because Sukhoi insisted on the stealth square nozzle at the last minute. When they already had a working stealth circular nozzle.

So to Claim, China is still behind and in „Russia it typically takes a year or less“ is purely a joke.

China is not significantly behind, but they still are a bit. The PD-14 has the certification of the engine while CJ-1000 does not.
And yes it does take only a year if there aren't any other issues. Most problems in engine design are usually.caught in the ground and flight test stage not the final certification. If they are pushing CJ-1000 with final certification it is because it already has passed the tests.
