This engine is available for export as implied by the OP. It has even got foreign buyer intent(s) last year:

"KP16-3D发动机的核心性能已全面超越国外先进同类产品,赢得国际认可,2025年成功获得意向订单。"
My sense is that a lot of the cheaper drones used in western countries probably do source Chinese turbojet. 3D printed one doesn’t Change the dynamics too much except having improved TWR.

Take with a mountain of salt right now but I’ve read some reasonably reliable rumors that VCE progress is ahead of the schedule. Can’t wait till TWZ catches wind of this a couple of years down the road :).

Specifically it boils down to whether J-36 will even use WS-15 as an interim when it LRIPs.
They are starting brainstorming work for what comes after VCEs. No clue what it is but these folks are not keeping still for one second hahaha. It’s like they have ADHD for engine designs now.

My guess for what’s next might be some kind of turbo-RDE.

Sky is literally the limit here. Key difference between China in the 2020s and China in the 200s or even 2010s is that the universities (folks on the entity list) are carrying a lot of the heavy lifting in researching next gen aerospace tech. We all mock Stephen Chen for taking research papers as absolute fact since most are nothing burgers, but some of them do end up getting taken seriously enough that they have actual prototypes in trials.

We mock Stephen Chen for deliberately misrepresenting research papers as if they are ready for imminent implementation (aka click bait).

If research were reported accurately there would be no issue.

Hehe

(I remember there was a VCE thread but I can't seem to find it) or maybe not

This application belongs to the technical field of aircraft engine design, and specifically relates to a three-duct variable-cycle aircraft engine.

A third duct is added between the inner duct and the outer duct, and a diversion fan is added behind the main fan. The diversion fan further includes:

a first-stage diversion fan

a second-stage diversion fan

The first-stage diversion fan is located inside the inlet of the third duct, in front of the inner duct.

The second-stage diversion fan is located inside the inlet of the inner duct.

The first-stage and second-stage diversion fans are connected by a drum/casing.

The second-stage diversion fan is connected to the front end of the low-pressure shaft through a diversion-fan shaft.

A variable-speed gearbox is connected inside the front end of the low-pressure shaft, and the output shaft of the variable-speed gearbox is connected to the fan through a fan shaft.
