It's highly related to J-20, because this will enable stealthy, non-radio-frequency-communications networks between J-20 and support planes. Not only, stealthy-radio-silent, and high bandwidth, the straight line/direct path of Laser Communications makes interception by the enemies highly...

"how do you solve stable point to point laser connection between two fast moving objects?" The same way USAF shoot down a missile moving at Mach 5-10 with an airborne laser. That's a lot harder than two planes pointing the communication lasers at each other at 144km, apart. IMO. If you are...

I don't know where you got this F-35 is a "4.88 generation fighter" from. It's grossly overweighted. It can't Super cruise. It's maneuverability is poorer than the F-15, F-16, and F-18, its supposed to replace. This thing is made for Cancellation, but instead its going to make 3000 copies, for...

And Quantum Radar and other Anti-Stealth Radars shows what a Trillion dollars big mistake/scam F-35 really is. Stealth, it (F-35) will not be in the future, no one will be, in fact. So air combat will go back to the time before "Stealth". Anyone who Can't run, Can't fight, Can't turn, or Can't...

China solved the problem of allowing J-20, and other planes, to form a inflight Stealthy Network using Laser Communication only. This Laser Communication Network allow a direct path communication distance of 144km and 2.5Gbps capacity. The distance could be extended using drones as relay...

Good eyes! The tough, heat resistant, ceramic based RAM coating is probably already done before the yellow primer is put on. The ceramic based RAM coating is not a sprayed on polymer paint, but must be baked in a high temperature oven. The yellow primer, in addition to other purposes, is to...

Let's have a minimum of 1000 J-20 by 2030. That's adding ~100 planes per year. If ShenYang don't have enough J-11, J-15, J-16 orders, they can have one or two J-20 production lines. Spread the production capacity around the country. So we can have another 1000-2000 J-20 easily, if we want to, or...

In addition to the dent, the Bump looks flatter. I wonder what speed is the plane flying at. Looking closer, its clearly a large dent, not just a optical illusion. This picture shows a smaller and less deep dent. Air flow into the intake changes according to various speed, Altitude, Angle...

We have been wondering how many J-20 will China able to produce each year. Producing J-20 is not just opening more production lines. The problem of producing enough critical components like airframe bulkheads and engine parts like high quality fan blades must be solved first. China have...

The Cone shape DSI Bump on the grey picture seems noticeably fuller than the yellow bird. Notice the yellow bird's landing gear bay door is open. It is at the lowest speed preparing for landing. We can't tell what speed the grey bird is at.

"However exactly that perfect or optimum shape is surely not that dent." I won't say "surely" regarding that "dent", unless I am an aeronautical engineer and did the computer simulation and modeling on DSI. DSI is a new technology only demonstrated on US and Chinese planes, not even the...

It is not a proof. But to make a flexible surface that is adjustable is not beyond anybody's ability. The value of adjustable DSI is to allow optimum airflow to the engine at various speed from low subsonic speed, to transonic speed and supersonic speed. The engineer must first find out the...

It shows the DSI Bump is flexible. The lighter color of the DSI probably signify its made of different material than the surrounding area.

Amazing! J-20 can turn without first banking. Click on the link. Normal turning with sharp banking first.

Here is my version of the modified poster for the 6th Anniversary of J-20.

"for SAC it is probably the final card to play to stay in fighter business after the Flanker series will end some day" True, that is a serious issue facing any fighter plane company. Many US companies were merged because of lack of orders. Shenyang could still make J-15 for PLAN for the...

Sounds like you are one of those Shenyang boys on the internet. Yang Wei is one of those rare and outstanding aviation engineering talent in the world. Get rid of him, so he can't work in his field, because he is good, could only happen in a hopeless country, that is going down the drain. I am...

I admit J-11d, J-15 and J-16 are pretty good. That's because Su-27 were very good in the beginning. May be calling FC-31 a crap is over the top. I have to admit. I have no liking of it, when it was first shown carrying on a truck covered up with a tarp. It may still be developed into...

You don't understand Chinese politics, Deino. CAC is the parent corporation of Shenyang Aviation and ChengDu Aviation. CAC's leadership is dominated by Shenyang people. Shenyang is mother of ChengDu and other smaller aviation company. In the 1960's, China decided to spread its heavy industries...

Most likely, FC-31 will not see the light of the day. There is persistent campaign on the internet forum organized by you-know-who, to push the PLAAF to buy this junky, little piece of crap. They started all kinds of suggestions that PLAAF should produce only 200 J-20 and produce 1000+ FC-31 for...
