Chinese Engine Development

@ rhino123

To admit I don't know the situation around Chinese tank engines, but the current JL-10 / L-15 simply uses only engines supplied by the Ukraine:

The advanced jet trainer (AJT) version = JL-10 is powered by two Ukraine AI-222-25 turbofan engines and the lead-in fighter trainer (LIFT) version si powered by two AI-222-25F with afterburner.

So far there is no Chinese option to replace them.

Indeed. However, since China had license to co-produce the AI-222-25, meaning they already had the blueprint and technical know how to do it, so there is no reason for what BigWang had proposed in doing.

how about the big engine for its biggest transport plane? It can be useful.

First of all... why would China want the tank engines? China can build their own tank engines. Secondly, why would China want Ukraine trainer engines? Is the trainer engines from Ukraine better than the ones that China already had and is using?

It may not be true. I remember China trying supply tank to Peru but Ukraine not willing to supply the engine and the deal fell thru.

The problem here might simply be that both manufactors - Ivchenko-Progress and Motor Sich - are both based at Zaporizhia in the Eastern part of the Ukraine) and as such in the mostly pro-Russia orientated part. Therefore the interest to leave is maybe not that great ... but please let us leave the politics out.

There's a rumor that China already acquired the blueprints and the design.

China already had a program in designing and developing the engines for the transport plane. And that program is in advance stage, so there really is no need to kill indigenous projects in favour for foreign ones.

Alot of China tank engines derived from German engine designs (derived not direct copies)... and this include the Type 99 MBT. If China had the capability to do that, why would they still direct import engines from overseas unless those engines are very cheap.

All in all, we cannot just view thing in a singular way. There are many parties involved.

Yes, Ukraine is in a dire state now, but was Ukraine going to collapse? Hardly. And don't forget there is another stakeholder involved - Ukraine herself. By doing what you have proposed, it might not bore too well with the Ukraine... Unless Ukraine actually collapsed and the scientists are all flooding out of Ukraine... then yes, it is a free market and China and grab some of these scientists.

Finally, China already had various advance programs in engines development across the board. Unless needed urgently, there really is no need for the Chinese to jump up and grab whatever come in the line. This is something that is of total opposite of their current philosophy.

Keep in mind that China having the ability to build foreign engines domestically does not mean China can export those engines to another country.

In case relevant companies in Ukraine collapse China might attract people with special knowledge and experience not to employ them in existing projects or even to abandon those projects to set up new ones for these people ( that would be going very far! ) but to learn from them. USSR did that with the German scientists they got after WWII ( see ) unlike the US who employed them directly ( think Werner von Braun ).
Of course this is not about the whole design of gas turbines, only about absorbing any knowledge about the production of turbine blades and the discs that carry them.
