Hangrui Power (航瑞动力) display booth at Zhuhai. The company's engines power the CH-4 (upgrade version) and CH-5 drones.

CASIC's CTF-3, CTF-9, and CTF-12 turbofans cover 650, 400, and 1000-kg thrust levels. Critical components of the CTJ-20 and CTJ-40 turbojets are all manufactured using 3D printing. These engines have broad applications in general aviation as well as UAV markets.

CASIC also showed off its piston engines in the 10, 75, and 100kW class.

There are four different engines in this photo, each of which appears to use a different TVC mechanism.
WS-10.jpeg
  1. Regular WS-10 on J-11, 16 and J10.
  2. WS-10 on J-20 with black outer petals except that this one has the fixed part using the same composite material as the petals.
  3. WS-10 2D TVC in F119 style
  4. WS-10 3D TVC, in the demo the nozzle swivels as a whole without changing exterior shape. We have also seen this in a CGI video some years ago. This is different from J-10 TVC's AVEN type which changes shape. I pointed this out in #7,056. However, @Blitzo pointed out that this may be result of a lazy job of the model in #7,058
So only the 2D TVC is certainly new, the 3D TVC may or may not be new.

Come to think of it, I'm more in agreement with Blitzo now since the baseline plume can vary its shape.

This AEP500 turboprop is pretty impressive with 5000 kW power. If they get it working then MA700 will finally get its engines.

If they change it to be used as a helicopter engine, i.e. a turboshaft, then it would have roughly the same power as the engine used in the CH-53K which is no mean feat.
