J-20A and C

[im you]

Personal description
This mod was aborted in 2020. In November 2023, when I finished the J-8II module of the instrument panel, I started to remake the J-20A. The opportunity was the J-20C that appeared in the movie "The Wandering Earth 2" and the J-20C screen avionics content map that appeared on China Sina. With the avionics content map as a reference, I began to reproduce this screen indicator, and then began to customize the weapon system, radar and RWR system for the J-20A.

J-20C《The Wandering Earth 2》

After all the work was basically completed, the state of the J-20A was that it could fly, fight and respond to missiles defensively. It was no longer the aborted J-20A that could only fly. Later, I was not satisfied with the poor ground steering function of SFM, but I had no knowledge of aerodynamics, and I didn't want to spend time learning those in depth. I could only look for open source EFM engineering projects. In the end, I used the EFM project of the F35 as a template, and changed the wingspan, wing area and chord to adjust the aerodynamic performance. In addition, radio and ils must be implemented, which are systems that cannot be implemented in the lua environment.

Differences between Model A and C
Model A can only conduct air-to-air and anti-radiation operations, and has no external weapons or auxiliary fuel tanks. Model C has a FLIR sensor and can attack the ground. The only laser weapon is AGM65E, and GBU12 can also be used, but the vertical downward vision capability of FLIR is too poor and it is easy to lose the target, so it is not recommended. The take-off and landing methods are conventional take-off and landing and VTOL.

tips:

The J-20C is dependent on the A-29B. After opening the DCS, you need to enter the cockpit of the A-29B before entering the J-20C for the first time.

For specific operating instructions, please see the doc folder of the mod

It all looks very good, but there are a few bad things. The pilot's model is poorly implemented. The star on the helmet, shown in 3D, is completely superfluous, as only a logo is used for it. The texture is mirrored exactly where the Chinese have put their numbers (rudder).

Will you be releasing any tutorials for how to use the systems in the aircraft?

No, the documents in the doc folder should be able to solve most problems

@im you when I try to spawn into the cockpit in VR DCS crashes, but it works fine in 2D.  Any idea what it could be?

I have not encountered any VR crashes, either J-20A or J-20A. Please upload the dcs.log if possible.null

Try starting DCS in single thread. Some modules of J-20C do not support MT.

Tried as adversary AI, and J-20A flight performance is very optimistic, same about RCS

Very nice mod !!!  from what I can see, it works well in 2.9.11 - I believe that this is - by far - the best J-20 mod available. 

[jjl9999]

anybody found what kind of VTOL usage can be done with J-20C ?

The flight performance is probably just because it's the J-20A with the thrust-vectoring WS-15 engine, which iirc isn't in full service yet IRL. That said, the RCS is definitely a little overtuned; I tried a BVR fight with it and Grinnelli's F-22A and neither of us could even detect each other on radar until about ~10nm, which strikes me as a bit much.

I reviewed tacview from fights, and 1.9M at 20k ft was no problem for J-20A with full weapon load and fuel, thrust vectoring affect manouvrablity, not acceleration or speed, and this look out of charts, beating 4th gen planes

It's not just TVC though, the WS-15 also has >25% more thrust than the WS-10C that most of the J-20's currently in service are using. It's meant to provide supercruise capability, I don't think that kind of performance is too much of a stretch.

Hi there,

@im you , 

are you still active? would like to get in touch.

模组做的很棒，感谢作者，最近出现一个BUG，歼20A切到霹雳10E，导引头锁定目标后，DCS会立即崩溃，这是诊断信息，希望作者可以修复
