The problem with the scramjets is that the engine doesn't work from 0 velocity. You need to be at least at like Mach 2-3 or whatever or else the engine won't even work. So you at most will see scramjets used as the second stage engine in a two stage vehicle where the first stage is typically a rocket engine. This adds cost and complexity.

I know it is no replacement for turbofan. I'm just commenting on how it is easier than turbofans.
It’s not a direct comparison, turbofan is a technology that has developed for like 50 years, and for America lead China 10 years, it need China to have technology in 40 year’s standard
similarly, for hypersonic technology, in this case ramjet, a 30 years technology, say for China to lead America for 10 years, it required America to have 20 years of foundation
For us and China, the 10 year gap between each of the technologies are the same, also the difficulties, otherwise it won’t take 10 years to develop, so for these two countries with strong technology fundation, the challenge are roughly the same for both tech
but for other countries with weak tech in these two streams, this would of course create a bigger barrier for turbofan as it requires more fundamental knowledge
24 types of aero-engines and gas turbines exhibited at this year's Zhuhai Air show. include WS-10 entire series for the first time.. Wohoooo
Today, the reporter learned at the press conference that there are 24 types of aero-engines and gas turbines exhibited at this year's Airshow China Aviation Development, and the newly unveiled exhibits Among them, electric hybrid distributed propulsion system, hydrogen fuel engine, low-cost engine, etc. will be exhibited for the first time, "Taihang" engine will be displayed in series for the first time, and AGT "three light and one heavy" gas turbine will also be exhibited collectively for the first time. (Headquarters reporter Liu Rongrong, Zhang Yixiao and Hu Rui ..
so my Guess is, WS-20 can also display.
possible contenders are , FWS-17 , CJ-500 and more information related CJ-1000 certification and CJ-2000 prototype.
WS-13 and WS-18 ?
obviously no WS-19/WS-15 display. we all know that.

Second most expensive metal, more than gold, palladium and platinum.
Rhenium is also used. But it is more abundant. Also iridium is so expensive.
The alloys name is tms-238.
Iridium is also very scarce in the Earth's crust. Until asteroid mining becomes a thing it will largely stay that way.
