Those numbers weren't a claim; those were straight up part of the video advertisement for Jiutian back at Zhuhai last year (picture three of that post)

Just in time for Jettank.
cute engine for the low altitude economy. Looks to be a piston engine. its rated speed reaches 6500 rpm, and its output power can exceed 53 kW. It is also simultaneously developing naturally aspirated and turbocharged rotary engine products, which will be gradually expanded to power medium-to-high altitude drones, supporting independent or random airworthiness certification; the product displacement covers 0.5L-1.5L, with power ranging from 50kW to 150kW, and can be applied to diverse fields such as urban air mobility, medium-to-long-distance logistics distribution, and aerial tourism.
CAS Aerostar (develops light turbofan/turbojet engine)/CAS Institute of Engineering, 西北工业大学, 西安交通大学 & 西空智造 has developed first fully 3D printed Turbofan engine which just completed ground testing. 3D Printing reduced core parts by 40% & weight by 25%, significantly improving T/W Ratio.
so now they are 3d Printing both turbojet and turbofan engines. Unbelievable stuff here.
西空智造 is an offshoot from 西安交通大学
While this one would be better posted in the S/VTOL thread instead of here - Should his claim be proven to be accurate, then this would indeed be a great news.
@伏尔戈星图 on Weibo alleges/hints that the S/VTOL-capable WS-XX engine under development (which is meant for a rumored S/VTOL-capable warplane which is also WIP) is capable of reaching a turbine inlet temperature (TIT) of around 2100 degrees Celcius (i.e. ~2373 Kelvin). His post alleged that this should enable the engine to produce a (simulated) lift thrust of 17.3 ton-force (i.e. ~169.7 kN).
More specifically, there appears to be mentions from an academic paper with a stated TIT of 1827-2127 degrees Celcius (i.e. ~2100-2400 Kelvin). I don't have access to the paper, unfortunately.
And as always - The usual discretions apply for this guy.

2100 °C is more than world's most advanced Engine F-135 with decent margin. which has 1,980 °C TIT.. mind boggling if true
@Alfa_Particle remember bro, what we were talking about. 2400K-2600k

Hm, that's double what the F135 generates under VTOL mode, which would also mean a liftfan twice as powerful as the one of F35B will be required to balance out. Unless he means 17.3tf is thrust of the whole system but that is quite a bit behind the RR liftfan at 18.9tf which I also find unlikely.
Hefei 中科重明, formed in 2018 under CAS & Hefei investment group JV, focuses on 3D printing of green fuel aero engine. It just concluded B+ Series of funding. 3D printing tech has reduced dev time from 10+ years to 3-5 years. It has patents for SLM printing of copper alloy & SuperAlloys + optimized design for green fuel.
