FWIW, this is an image of the official handover/unveiling ceremony of an improved Taihang variant. As to which WS-10 variant this is, I have no idea.

- R&D began in December of 2015.
- Design passed appraisal in February of 2018.
- Two sets of casting blanks completed in February of 2019.
- Blades already installed on an actual engine and are currently undergoing testing.

XX-15 low-pressure single-crystal turbine blades:
- R&D began in May of 2018.
- Casting blanks for prototype blades handed over in April of 2019.
- The first appraisal meeting and handover of remaining casting blanks are planned for June of 2019.

I was thinking about the significance of this one...that they’re making casting blanks now seems to suggest some work is starting to set up production now.

Another excerpt on WS-10. I'm not sure when this document was published, so I can't place it precisely on a timeline. In any event, this is old information.

XX-10 high-pressure single-crystal turbine blades:
- Has passed the initial appraisal and been tested for 500 hours.
- Has achieved small-batch production.

Ukrainian President Zelensky has approved sanctions against Chinese buyers of Motor Sich .

Please, Log in or Register to view URLs content!

The Chinese paid more than $ 2.5 billion for the Ukrainian engine plant. But they will not be able to use the plant now. Apparently, it will not be possible to return the money either.

Who was sanctioned for three years:

Skyrizon Aircraft Holdings Limited, a company registered in the British Virgin Islands;

Hong Kong Skyrizon Holdings Limited, registered in Hong Kong, China;

Beijing Skyrizon Aviation Industry Investment Company, registered in Beijing, China;

Beijing Xinwei Technology Group Co., Ltd, registered in Beijing, China;

a citizen of China, Wang Jingwei (Wang Jing).

What they suggest:

Asset blocking;
restriction of trading operations;
ban on transit through the territory of Ukraine;
preventing the withdrawal of capital from Ukraine;
ban on transactions with securities;
the ban on changing the size of the authorized capital in Ukrainian companies in which the participants of the sanctions list own a share of ownership or influence the management and activities of such companies.
