For those new to this thread, the WS10A ( AKA Taihang) engine, is a turbofan engine developed by the Shenyang Liming Aircraft Engine Company to power the Chengdu J-10 and Shenyang J-11B jets. Some specs:

  1. Type: It's is an afterburning turbofan engine.
  2. Thrust: 132 kN (29,670 lbf) of thrust with afterburner.
  3. Bypass Ratio: The engine has a low bypass ratio, which is typical for fighter jet engines.
  4. Compressor: A multi-stage axial compressor, common in modern turbofan engines.
  5. Turbine: includes a high-pressure turbine (HPT) and a low-pressure turbine (LPT) to extract energy from the hot gases and drive the compressor and fan.
  6. Afterburner: It is equipped with an afterburner
  7. Control System: incorporates a full authority digital engine control (FADEC) system.
  8. Development: the WS-10A and its upgrades (WS-10B, WS-10C, and WS-10IPE) are in full production and form the backbone of China's fighter engine fleet.

Pardon, but it seems, the only one new to this thread is you and all the data you posted is either dated or plain wrong!

So what's the point posting it as if it would be something new?

Seems you just copy&pasted some nonsense from a random site!

from Northwestern Polytechnical University on a novel 2D thrust-vectoring nozzle capable of deflection angles up to 90 degrees, far exceeding the typical 20-ish degrees of other 2D TVC nozzles.

Two successive patents (

) on the same 2D TVC nozzle design from Sichuan Gas Turbine Institute, a subsidiary of AECC. The two patents were filed six months apart, and you can see the mechanical refinements and modifications made to the nozzle in the second patent.

IIRC SGTI is heavily involved in the WS-19 project. Fingers crossed.

In other news, some slideshow captures from a previously seen presentation of a firm extensively apply additive manufacturing to make 2D TVC parts:

Interesting to note that they've already had two generations/iterations of the 2D TVC system, with the second iteration having petals that can split from the centerline, reminiscent of a previously seen patent.
