Do Canards Effect Stealth? New Chinese Fighter

[Dominato3r]

I was looking at China's new stealth fighter and was wondering how the Canards would effect its stealth performance. My thinking is now that stealth is more based around different angles than absorbent materials - Canards are a weird variable to control.

J-20:

Stealth in name only.

 

[PhoKingGuy]

So who did they rip this off of?

 

[PottedMeat]

hahah so that's what a bootleg F22 looks like. can i pick one up at a flea market for maybe a million dollars?

at least they're not knocking off just us:

(The existence of the J-11B, essentially a “bootleg” version of the Su-27, has been a strain on relationships between the Russian and Chinese industries.)

 

[Dominato3r]

Well, it does bear a lot of resemblance to the F-22 and F-35 but that's kind of the new age look for these fighters anyhow.

 

[shiner]

It will never get off the ground with all that lead in it.

What?! AT hasn't heard of this thing yet? :hmm:

China is notorious for copying and ripping off the work of other nations, and you can bet that they did it here as well.

take off the red star and the only thing it looks like is a F22 from all sides.

you said it was it was a stealth jet...

Nothing more than the aesthetics of course.

"Made in China"

LMAO

 

[OCGuy]

HAHA. That looks like some crappy version of the Raptor.

 

[FM2n]

Does it have on-board WIFI?

There are different levels of stealth that can be applied to an aircraft. This craft is a semi-stealth aircraft; the whole point is much lower cost of construction and maintenance than a full-stealth aircraft, while having reduced observability.

Oh, they'll try to copy the avionics too. I'm sure plans were lifted from all the hacking they were doing. However, some parts will be unavailable, so they'll have to improvise. If you pop open the main cockpit panel, you'll see an Acer netbook duct taped to the wall for the "flight computer."

Pffft they can copy airframes all they want, we are light years ahead in radar and avionics, and pilots; that's what makes the Raptor and Eagle.

Available at Walmart for $107.63, ROLLBACK!

Canards won't affect stealth much, they aren't employed except for high maneuverability, eg dogfighting, they won't move much during cruise. Funny thing is they still think its about dog fighting and maneuverability, and the Raptors will just stay out of their reach and out range them and launch missiles at their ass from 1000 miles away.

Fancy acrobatics don't mean shit in modern aircraft, its all about who can see who first from the farthest away and who has the better missiles. IMO we need stealth A2A missiles that leave no chance for countermeasures.

The engines are most likely members of the Russian Saturn AL-31F family, also used on the J-10. The production version will require yet-to-mature indigenous engines.

Translation: The Chinese still haven't quite yet figured out how to reverse engineer the Russian engines to create their own "indigenous" engines.

This. There's no such thing as perfect stealth, it's a spectrum.

As for the OP, one principle of stealth is to have as few edges as possible. This is one reason why the B-2 has no tail, why the proposed FB-22 would have no tails or even any moving surfaces (!). So a canard would be a 'non-stealthy' feature, but it doesn't mean it won't stealthy to some degree.

They did try to make their own engines for the J-10, but they didn't work correctly.

But yeah, they can't make their own engines and now we are supposed to believe they made a stealth fighter that can compete with the F-22 (Or even F-35 and PAK FA)? Yeah. Okay.

Pray tell which air to air missile in the U.S inventory has a 1000 mile range?
