What's new

FGFA vs J-XX

Live updates on Chinese boards said that there was a high speed taxi trial today, it lifted its head a little bit but immediately released the parachute after that so it didn't fly. Hopefully we'll see the first flight very soon.
 
I disagree.The J20 is a heavy fighter focusing on air superior.Its just too heavy for a Chinese aircraft carrier which will be mostlikely around 6,5000 tons.The navy will require a multirole stealth fighter,lighter and enhanced on air to ground.Plus the SAC already worked on the J15.I think the SAC will get the navy stealth fighter contract.Rumors said the SAC is working on a double engine stealth mulitirole fighter,that could be the future one for the navy,but its still a big question marker.Anyway,we had the J15 now,maybe the navy stealth fighter is not that urgent.

i am referring to the land-based J-20......

stealth...

I,M GOBSMAKED... I think the chinease have a 5th gen fighter...

And it looks damn cool more American than Russian. IN CONCEPT.
 
Pardon me but........ the position of the red star on picture # 2 is different from all other pics......... so are there two prototypes or is this a photo shop...........

have you ever considered that the pictures could be taken from different angles etc

Over the last few days imagery of what is claimed to be China's new stealth fighter has appeared on a range of Chinese Internet sites. There have been no official disclosures as yet, so many of the claims appearing in the media may only be speculation presented as fact.

The aircraft may be a technology demonstrator or a prototype for a mass production fighter aircraft. The latter is however much more likely, given that the PLA Chief of Air Staff claimed an IOC later in the decade.

What the imagery shows is a large fighter, approaching the size of an F-111, with a canard delta configuration and pair of outward canted all moving vertical tails. This configuration will provide good sustained supersonic cruise performance with a suitable engine type, and good manoeuvre performance in transonic and supersonic regimes.

Of most interest is the stealth shaping, which is considerably better than that seen in the Russian T-50 PAK-FA prototypes and in the F-35 Joint Strike Fighter. The Chinese design appears to be largely built around the stealth shaping design rules employed in the F-22A Raptor. The chined nose section and canopy are close in appearance to the F-22. The trapezoidal inlets are closest to the F-22, but employ an F-35 style boundary layer control design. The wing fuselage join angle, critical for side aspect stealth, is very similar to the F-22 and superior to the Russian T-50 PAK-FA prototypes and the F-35 Joint Strike Fighter. The flat lower fuselage is optimal for all aspect wideband stealth. Planform alignment is impossible to assess until in flight imagery becomes available.

The aft fuselage, tailboom, strakes and nozzles are not compatible with high stealth performance, but may only be stop gap measures to expedite flight testing of a prototype. The airframe configuration and aft fuselage would be compatible with an F-22 style 2D TVC nozzle design, or a non-TVC rectangular nozzle designed for controlled infrared emission and radio-frequency stealth.

The PLA have not disclosed the engine type. There are claims that the Russians supplied supercruise capable 117S series engines - these would not be sufficient to extract the full performance potential of this advanced airframe.

The airframe configuration is compatible with ventral and side opening internal weapon bays, and large enough to match or exceed the internal weapons payload of the F-22A Raptor. Internal fuel fraction may also be high, given the fuselage configuration and large internal volume of the big delta wing.

Other unknowns are the intended sensor suite. China has yet to demonstrate an AESA radar, or an advanced indigenous emitter locating system. However, these could become available by the time this airframe enters production.

The size of the airframe, and its evident focus on supersonic persistence, suggests at a minimum an intention to provide a long range interceptor for air control in the Second Island Chain geography. This capability by default would provide the ability to penetrate an opposing IADS to destroy assets like AWACS, other ISR systems, and tankers. Suffice to say, with suitable internal weapons, the design could be employed as a penetrating strike aircraft, in the combat radius class of the F-111 or Su-34 Fullback.

The notion that an F-35 Joint Strike Fighter or F/A-18E/F Super Hornet will be capable of competing against this Chengdu design in air combat, let along penetrate airspace defended by this fighter, is simply absurd.

APA will produce a detailed analysis at a future date, once more technical material becomes available.
