Chengdu J-20 5th Generation Aircraft News & Discussions

i think this design surely give advantage from ground radars. i m not expert but one a bay is open the plane lose all its stealthy to ground radars. so it does gives some if not huge advantage to J20. but it all depends if F22 actually need to remain open his bays in WVR Fights.

sorry dubble post...

You must be talking about your friends.

One guy said it is about RCS...Another said it is not...Should work on coordinating their propaganda...

In terms of propaganda, recent democracy propaganda is 100 nastier than communist ones.

In a democracy propaganda, a sh!tty design like leaving the whole weapon bay wide open would appear to be more stealthy than a shut closed one, not to mention more expensive the open-bay design have to be… Oh, well, that’s 99% taxpayers’ money. Duh!

This is from the same crowd that once believed the F-22 is vulnerable in rain, without understanding one whit of how and why...

OMG...!!! Look at all the 'stealthy' stuff being washed away...!!!

Our mr gambit has reaches highest level of nirvana, water splash can be called rain? Those water pump out has zero level of acidic level, while you cant be sure of rain fallen from sky?

I've been to Tyndall AFB, and while it was raining at about 40 degrees Fahrenheit, the F-22 was getting its engine maintenance, in the cold weather and in the rain, hell there was a bunch of Raptors in "Raptor Country" in the rain taxiing and in open hangers.

Lockheed Martin F-22 Raptor - Wikipedia, the free encyclopedia

Lieutenant Colonel Wade Tolliver, the squadron commander of the 27th Fighter Squadron commented: "the stealth coatings are not as fragile as they were in earlier stealth aircraft. It isn't damaged by a rain storm and it can stand the wear and tear of combat without degradation." However, rain has caused "shorts and failures in sophisticated electrical components" when the Raptors were briefly posted to Guam.

Boeings newest F/A-XX sixth generation designs.

And whats that on its front... oh its a canard placed exactly like the J 20s LOL

In fact the wing geometry looks almost identical.

funny. what's going on with american physics?

Boeing unviels updated F/A-XX 6th gen fighter

PrintBy: Dave Majumdar Washington DC 1 hours ago Source:
Boeing is unveiling an updated version of its F/A-XX sixth-generation fighter concept at the Navy League's Sea-Air-Space Exposition in Washington DC this week.

The tail-less twin-engine stealth fighter design comes in "manned and unmanned options as possibilities per the US Navy," Boeing says. The design features diverterless supersonic inlets reminiscent of those found on the Lockheed Martin F-35 Joint Strike Fighter.

The Boeing concept also features canards, which is somewhat of a surprise because the motion of those forward mounted control surfaces is generally assumed to compromise a stealth aircraft's frontal radar cross-section. But the lack of vertical tail surfaces suggests the aircraft would be optimized for all-aspect broadband stealth, which would be needed for operations in the most challenging anti-access/area denial environments.

Also of note in the manned version of the company's F/A-XX concept is the placement of the cockpit-rearward visibility appears to be restricted without the aid of a sensor apparatus similar to the F-35's distributed aperture system of six infrared cameras.

The Boeing F/A-XX concept is a response to a USN request for information (RFI) from April 2012 soliciting data for a replacement for the service's Boeing F/A-18E/F Super Hornet and EA-18G Growler fleets in the 2030s. The Super Hornet fleet is expected to start reaching the end of the jet's 9000h useful lifespan during that time period.

"The intent of this research is to solicit industry inputs on candidate solutions for CVN [nuclear-powered aircraft carrier] based aircraft to provide air supremacy with a multi-role strike capability in an anti-access/area denied (A2AD) operational environment," the navy RFI stated. "Primary missions include, but are not limited to, air warfare (AW), strike warfare (STW), surface warfare (SUW), and close air support (CAS)."

Navy leaders had said at the time that they expect any new F/A-XX design to have greatly increased range and offer far superior kinematic performance compared to existing tactical aircraft

it looks like a tailless j-20. the canted carnads are in same level of the main wings, similar shape, dsi..bla

The american copy the Chinese J-20. Shame on the American fanboy who always called Chinese copycat.

We can only say two things -

* This is just a concet-plan

* Same need, same configuration

Once again, we can see that how hard is to compromise the contradictionnal aerodynamic need in both Supersonic and transonic fields. We can also say that maybe Chengdu's guys have made a good choice since 2001 (Just a reminder of the R&D paper "一种小展弦比高升力飞机的气动布局研究").

Research on the Aerodynamic Characteristics of a Small Aspect Ratio，High Lift Fighter Configuration

[Abstract] Focused on the features of stealth，super—maneuverability and supersonic cruise of the future fighter，the authors identified the main difficulties and gave some practical solutions to lift—drag characteristics at sub一／tran—sonic speed，high A．O．A．aerodynamic performances at low speed and supersonic drag characteristics．

The authors believed that design goals could only be achieved by studying flow principles deeply，digging up the potentials of present aerodynamic improving measures，developing new aerodynamic concepts，adopting interrelated integration and flight control measures and compromising on the multiple design points．

[Key words] aerodynamic configuration；supersonic cruise；stealth；post—stall maneuvers

However, this is not the reason to laught on the others, whatever they have said before. I knew Chinese friends with a better quality than this.

Sometimes, you know that you're right and that's enough...

that boeing latest f/x 6th gen concept just made all the so-called experts look like fools. even if you don't want to laugh you just can't help it

China's J-20 stealth fighter: 'design is 25 years old'

Oh no, but the canards will flip and flap around and give this aircraft the RCS of a B-52.

The trailing edges of the canards will also diffract onto the main wings and fuselage. Isn't that right gambit?

check this out. the koreans are planing to make j-20 clone too. everyone is copying dumb chinese 25 year old design
