Chengdu J-20 5th Generation Aircraft News & Discussions

Hmmm??? Henry K. mentions, there are some changes visible, that hint to a future TVC engine ... can anyone spot them?

J-20A + WS-10C - 20191030 - 3+mod.jpg

Production - Yes
Mass-production - Not yet.
J-20 is still deployed in one Air Brigade (I count combat brigades, not Test Brigades) which i am sure it is not fully equipped yet...
The question in when the J-20 will go mass-production and on what technical conditions.
main problem for J-20 is its not have it main engine WS-15, J-20 currently flying with interim AL-31FN or WS-10 series of engine, WS-15 will be available in 2023 @bahadur999

A Chinese aero expert back in 2017 already claimed that the prototype 2017 was testing with the WS-15.

But the CD forum would just deny it as usual, just like their stupid joke with the Type 075.

Sir no official confirmation of J-20 equipped with WS-15 so far , recent images show us/ give us the hint that current J-20 is still using Al-31FN for older prototypes, and new production models using a version of WS-10 at best @ChineseTiger1986

Bro, CD forum ≠ China's official confirmation.

They are just a private forum running by a bunch of military amateurs.

The J-20 starting to equip with the WS-15 engine with TVC has already been hinted by several military insiders including the chief designer of the J-20.

So far, there are three PLA officials can prove that the J-20 has been equipped with the WS-15.

Professor Song Xinzhi: He is a aerospace equipment specialist from the PLAAF.

Senior Colonel Xu Yongling: He was a veteran test pilot for the J-10.

Chief Designer Yang Wei: He is chief designer of the J-20 and will also carry the project for the 6th gen aircraft. Last year during the Zhuhai air show, he had already hinted that the J-20 using the TVC engine. Since we all know how a TVC version of the WS-10 looks like, and if the J-20 also using the TVC, then it can be nothing other than the legendary WS-15.

Ask any Chinese member to verify the validity of my statement.

Fully agreed ... but I think point is, so far no image has been leaked, what is not surprising given the importance of the WS-15 and in mind of how few images of the WS-10-powered J-20 we have.

According to Yang Wei, the J-20 has already equipped with the TVC. He is the chief designer of the J-20, no one else can know the specs of this aircraft more than him.

The problem is that this TVC looks very different from the WS-10 TVC demonstrator.

So they cannot be the same engine.

Again; fully agreed ... but still I think the point is, so far no image of any WS-15 has been leaked, what is not surprising given the importance of the WS-15 and in mind of how few images of the WS-10-powered J-20 we have.

Not sure, why my reply was misleading.

The new leaked images could be the WS-15 being mistakenly labelled as "WS-10B/C".

Since it does look similar to a WS-10 engine, but still different from a WS-10B with TVC.

You can see how even Russia's newest izdeliye 30 also looks like an AL-31 with sawtoothed nozzles. This indicates that the izdeliye 30 still shares the same bloodline with the AL-31 family despite being a generation more advanced.

By making the same analogy, the WS-15 can also look similar to the WS-10 but with sawtoothed nozzles.

@ChineseTiger1986 What do you think is the likeliest thrust rating for the first variant of the WS-15? The consensus seems to be 180kN.

Professor Song Xinzhi had also stated by 2017 that the WS-15 got its afterburner thrust around 180kN.

yes most probably 43,000 lbs like F35's engine but question remains whether this engine will be low by pass engine like F-119 is or high by pass engine F-135 is

It is low by pass like the F119.

Excellent. I understand that the WS-15 uses a second generation monocrystalline superalloy (DD6)

There are already third and fourth generation alloys, so the WS-15 will have a lot of scope for improvement.
