Aviation Week First Analysis of JXX

[Storm Force]

Bill Sweetman from Aviation Weeks made some intresting points

He thinks The JXX is almost as Big as F111 strike aircraft from the 1970s. JXX could be a long range strike plane rather than fighter

The size is estimated at 75ft long far larger than both F22 & T50

He also states This maynot be a genuine prototype and just a tech demonstrator like the (YF23) so could be some massive changes yet.

The engine is stil russian powered and there is news that the chinease are haviing to rely on russian engines for all current fighters including J10 & J11B as well as JXX testing.

Anyways here the 2 page analysis

No, he said the following:

The major open question at this point is whether the J-20 is a true prototype, like the T-50, or a technology demonstrator, with a status similar to the YF-22 flown in 1990. That question will be answered by whether, and how many, further J-20s enter flight testing in the next 12-24 months.

The PAK-FA is being considered prototype because it is, essentially, a Su-27 with sharp angles and, maybe, some RAM. We won't know for sure whether the T-50 was a prototype until we see the LRP version. The J-20, on the other hand, looks and feels like an entirely new aircraft, hence, it can be considered a "technology demonstrator", i.e., a platform that demonstrated new technology. In engineering circles, there can be little difference between a successful tech demo and a prototype. The YF-23 was called a "prototype" before it was canceled, at which point it became a "tech demo".

Let's see whether the J-20 undergoes any major changes before its first test-flight.

PAK FA does looklike a natural evolution from FLANKERS which themselves are stunning designes.

Likewise F15 evovled to F22

You must be smoking the strongest smoke available dude , F-15 is a totally different design to F22 and btw both don't look identical where T50's Intakes are a direct copy paste of flanker family.

I don't think that the air-superiority capabilities of the plane will be down played even if it turns out to be a strike fighter.

In a 2009 television interview, He Weirong (何为&#33635, deputy commander of the People's Liberation Army Air Force, stated that China had multiple such programs underway and that an as-yet-undesignated fifth-generation fighter developed jointly by Chengdu Aircraft Corporation and Shenyang Aircraft Corporation would be in service by 2017-2019. The test flight was conducted on December 11, 2010

PAK-FA/T-50 - Sukhoi OKB.
Su-27 series - Sukhoi OKB.

F-15 Eagle - McDonnell Douglas, later Boeing
F-22 (airframe only) - Lockheed Martin

Unless Boeing shared highly proprietary and sensitive information with their greatest rival (the same company they were competing with for the JSF contract), your theory of F-22 being a natural progression of the F-15 design doesn't hold water.

I don't think that the air-superiority capabilities of the plane will be down played even if it turns out to be a strike fighter.

By many accounts, China has two separate Stealth programs underway, one in Shenyang the other in Chengdu. Stealth technology's greatest advantage is against ground radars anyway, so it's only natural that the first aircraft out would be a dedicated strike aircraft (like the F-117 or B-2).

However, if this is primarily a strike aircraft, why in the world would it have Canards? Isn't the primary purpose of a Canard-Delta design high-speed maneuverability? That feature, alone, would be enough to defeat the "ground strike" hypothesis.

My point exactly. It does not make sense for China to obtain a pure strike aircraft before an air superiority one. The pressure of neighboring countries obtaining F-35s means that the plane shouldn't sacrifice air to air capabilities.

From what I've been able to gather SAC is working on something akin to a "Silent Flanker". Not nearly enough to counter other Stealth Air superiority fighters like the F-22 and T-50.

Canards improve a delta wings low speed high alpha maneuverability.

the estimated wieght of this planes seems to be huge
75000-80000 lbs without payload.....
what will be estimated thrust required to give it a decent thrust to weight ratio....and good manuverabilty
and supercruise.....

Now this is what unbiased journalism is supposed to be, unlike Kopp's not too subtle jabs at US and fawning exaggerations towards China.

Kudos to Mr. Sweetman.

Interestingly.. Bill sweetman is one of the critics of the F-35 program..and was.if I recall correctly ..suspended for some of his comments on it.
His second blog on the J-20 is also quite interesting .

T50 Inlet does not have the invisible capability, but the plane shape is beautiful. Jxx the body too long, the feeling of imbalance.
