I would like to receive some information about the TEI TF-35000 if possible.
So far, we have only seen a few PR clips and short test runs of the TF-6000, which seemed more like PR demonstrations than full-fledged test campaigns. I know TEI told us they already finshed more than 1XX Tests with TF-6000 but there is virtually no public material on the TF-10000, and official communication on the TF-35000 is essentially limited to the published design and spec sheet on the TEI website.
According to TEI, the TF-35000 prototype is currently under construction and is scheduled to undergo its first ground tests in early 2026. At the same time, we know that turbofan programmes are traditionally subject to very strict secrecy. Nevertheless, it is frustrating that there is virtually no reliable interim information – except for the statement that the first airworthy prototype is to be integrated into a test aircraft from 2028/29 onwards.
For me, it's very hard to believe that because we won't even see anything about TF-10000 Engine.
From the outset, it was clearly communicated that the TF-6000 and TF-10000 engines would primarily serve as technological test beds. They will be used to test all critical key technologies for the TF-35000: modern FADEC systems, high-strength metallurgy, single-stage blisk blades made of single-crystal superalloys, pressure-stable high-temperature combustion chambers, etc., as well as advanced thermal protection and barrier coatings that must be able to withstand operating temperatures in excess of 1,700+ °C on a continuous basis. These technologies are essential for reliably advancing into the 35,000 lbf thrust class in the future.
