Tldr;
- GE T700 engines used in T70 Skorsky will have over 60% local content ratio including combustion chamber.
- TS1400 started at least one year before it was announced, and it is in detail design phase( aka concept design is chosen) 3d printers are being used in many prototype...
There is an on going investment to start producing these parts Locally. I believe the news is available in this topic. A local conglomerate is working with foreign company as JV.
It doesn't work like that. You can't cast Engines with such precision. At Least, As engineer, I never heard such high precision casting. For instance, Renault cast Engines in Romania then it mills in Turkey.
Edit; my bad, precision in language.
Afaik, first trial is done in a local firm but the
Quality wasn't as expected, That firm suppose to iron out the issues until mass production. We will see.
You really should watch testimonies of high level NASA officials . They never believed that this was possible and They testified for this in Senate committees. This was one of the biggest blow to SpaceX face.
On the contrary, Most of NASA veterans and many astronauts like Neil Armstrong openly said, they don't believe what SpaceX trying to achieve is technically possible. Until, SpaceX succeeded it.
