Chengdu J-20 5th Generation Aircraft News & Discussions

[Martian2]

To commemorate the one-year anniversary of the official disclosure for the J-20 Mighty Dragon, I want to inform the new members (or silent viewers) about one of the most popular (i.e. Top 7) YouTube videos on the J-20.

It is highly informative and covers basic stealth principles, such as continuous curvature and planform alignment. It also happens to be my creation. There are over 85,000 views and I hope you like it.

----------

Also, I have a second YouTube video that shows the J-20 prior to takeoff, firing its engines, and launching. It was a special release to celebrate the August 1st anniversary of the PLA.

It is worth watching from beginning to end. You just have to wait through the first 20 seconds as the aircraft is towed into position. After that, it's all action-packed.

----------

While I'm on the subject of informative and entertaining military videos, if you are interested in China's Shi Lang aircraft carrier or the anticipated complement of navalized J-15 Flying Shark fighters then please watch my video on "China's J-15 Flying Shark Naval Fighter."

The beautiful soundtrack alone makes this video worth your time.

----------

Finally, I would like to mention the latest addition to my collection of entertaining and instructive military videos. My brother, Felix, decided to cover the different flight stages of an intercontinental ballistic missile (ICBM).

Outside of big-budget Hollywood trailers, I believe his video on "America's Thermonuclear Strike" is the most exciting on YouTube. See for yourself and decide whether you agree.

Dude AWACS like ZDK-03 are very useful for detection. but there is still question who detect first.

and it's f22 for sure thanks to it's passive detection abilty

But there are many alternatives.
Just need to Hack the F22 AN/APG-77 signals when F22 penetrate into enemy land., CIP(Common Integrated Processor) instructions of F22 can be alternated.When virus has penetrated into CIP THEN CIP instructions are alternated.Now we have control over F22 than the US airbase. Just see the advantage of this.
Even if CIP of f22 is alternated with malware. It can malfunction the F22.

well u tell this cool story to any hollywood director they would make a hollwood film on it

nice cool pics j20 blackdragon , i really liked that escpecially of F22 it's sexy raptor

every plane has passive detection. if what you said was true, every plane would just maintain radio silence... doesn't happen.

But not all are the same in terms of quality and capability. The F-22's ALR-94 system provides 360 deg passive detection, yes, but the 30+ conformal antennas on the wings and fuselage as an integrated system is good enough that it can actually direct an AMRAAM to an active transmitter from any direction that tries to find the aircraft, leaving the missile to activate its own transmitter at the appropriate moment to completely lock on the target. In other words, if the J-20 goes active in trying to find the F-22 he will die, but if he does not try to find it, then he will die just a little later.

The efficacy (alleged) but I have no reason to doubt it, my experience with both russian and american systems is that they do exactly what the system is meant to do... of the passive system is remarkable and perhaps more lethal than the actual VLO of the raptor itself.
The point is...... can the limited radar on the missile lock on a LO target? Personally I doubt it. A very large percentage of AiM -7s and AiM-120s I have seen fired (the 7s in all three configurations, sea, air and land launched) I have monitored have less than brilliant performance and that is under ideal conditions against target drones.

I very much doubt current versions of active or semi active missiles can lock on a LO target.

there is little reason to believe that the J-20 does not have a similar system.

in addition, i believe that optical sensors have a bright future. visible stealth is not really possible yet and on clear days, optical systems can see for 70 kms which is good enough for final guidance.

You're assuming the small active radar seeker in the AMRAAM can even acquire the J-20 (or any stealth aircraft).

As i said above, the same goes for all active or semi active missiles in the world, be it russian, american, french or chinese .. if your main radar has trouble picking up a LO target, the missile seeker has very little hope.

what do you think of optical sensors for guidance applications? no such thing as optical stealth on aircraft (yet...) and some optical sensors can sense up to 70 km.

Depends on the range. For at least the next 20yrs, low radar observable fighters will be very limited in deployment, this is being generous to the J-20 enough to place it into this category. So for that, the current evolution of radar guided missiles will continue to gain lethality enough to make it effective against LO targets.

the sensors are optical, but usually in IR region. They can pick up a fighter sized target at about 70km head on, but at given altitudes and conditions. your optical sensor will not pick up a low flying target at 70km and an F-35 for example would not fly high all the time.

even so, it is hard to tell the vector of the plane in the IRST, and more over , even if the IRST sensor picks up the plane, a disturbing piece of news i got recently (last year) was that the IR sensor on an IRIS-T missile (state of the art) tracked the rear end of an F22 happily ... but could not get a lock on it ... and the F22 was close enough for the JHMS i.e. visual range .. that is really disturbing ..it means that even say an EF2000 were to drop behind an F22 by surprise and fired a salvo of IRIS-T missiles, some missiles would never acquire a lock on it.. the success rate of a missile that is fired without a lock on is ... a roll of a die at best..

gives an indication of how effective the nozzles on the raptor are. The russians claim the seekers on their short range missiles are more sensitive than the IRIS-T.. perhaps they are, but nobody knows for sure.
