I know the comparison is made but I always saw the J35 bigger. Wonder how close in size it will be to F22.

The J-35A boasts dual engines for potential enhanced range & power. Compromising on weapon payload to be more stealthy for the J-35A? Less complex and easier to build up in large number to overwhelm the opponents.

J-35A will be a much superior machine than the F-35A/C when it comes to both aerodynamic performance and also stealth.

Only in radar and electronics will the 2 match each other with similar capability.

It is silly to compare a non-supercruising F-35 with deliberately compromised stealth, against a true 5th generation fighter like J-35A with no compromise in any area.

I wouldn't be too sure on this! even more with such bolt claims it will be superior!

For the moment it’s weakpoint - or at least uncertainty - is its engine. If it indeed still uses the WS-13-based (aka an improved RD-93) WS-21 with allegedly 93+ kN of thrust, it seems to be rather underpowered for a fighter of that size (in fact it has almost the size of a F-22).

J35 is more closer than F35 than F-22 in term of size

F35 =50 feet

J35 =56 feet

F-22 =62 feet

Here's a complete breakdown of the engines.

WS-9: Based on the Rolls Royce Spey. Used by JH-7/7A.

WS-10 series: Low bypass, high-thrust class, equipped on J-10C, J-11B and later models, J-16, interim engine for J-20 (WS-10C), and soon to be equipped on J-15B. Basically equivalent to the F110. Developed from the CFM-56 core, with AL-31 characteristics. Dramatic improvement in TBO time, thrust, reliability, etc. as development went on. There's also a 3D TVC testbed equipped on a J-10. WS-10B *allegedly* have a wet thrust of ~130-145 kN.

WS-13: Low bypass, medium-thrust class, developed from RD-93. Equipped allegedly on the JF-17, and FC-31/J-35 prototypes. Developed into the WS-13E/21.

WS-15: Low bypass, high-thrust class, potentially the most advanced high-thrust engine to be fitted in a twin-engine fighter yet. Indigenous design, basically the equivalent to the F119. To be fitted in J-20A and potentially the J-20S. *Allegedly* have a wet thrust of ~181 kN.

WS-17: Low bypass, low-thrust class, and (I believe) non-afterburning. Equipped in trainer jets like the JL-10.

WS-18: Medium bypass, developed from the Soviet D-30. Equipped as an interim option on Y/YY-20.

WS-19: Low bypass, medium-thrust class. Indigenous design, equivalent to the EJ-2x0/F414-EPE. Currently undergoing tests and to be equipped on the J-35/31. ‘Confirmed’ thrust of around 10 tonnes-force (~98 kN), but I've heard figures of a maximum wet thrust of ~112.8 kN (UNCONFIRMED).

WS-20: High bypass, based on the WS-10 core. To be equipped on Y/YY-20.

WS-21: Also known as WS-13E, developed from the base WS-13. Improved life cycle , MBTO and thrust. Interim engine option for the J-35/31. 93kn of thurst.

WS-6/8/12 are cancelled projects.

Nope figures of 100-110kN have been put out and even at 100kN each, it would supercruise.

It is insulting to compare such a true air supremacy fighter to a "jack of all trades" F-35 in air combat. Better to put it up against F-22.

Absolutely no way that WS-19 would have anything less than 10:1 T/W ratio and it may even hit 11:1.

This is going to be a fighter used by both PLAN and PLAAF and so expect nothing less than the best of Chinese aerospace technology being rammed into it.

PS - Why do you think the Chinese are not going to successfully develop the 5th generation WS-19 engine? They managed it with the even harder higher thrust WS-15 and so WS-19 is only a matter of testing and refinement.

The idea behind China's design of the J35A is very clear, while the US F35 considers global applicability. This fighter jet has multiple functions for use by the US and its allies. The era of designing F35 coincided with the golden age of the United States, which was the world's hegemon. China's J35A emphasizes aerial confrontation, with the core goal of countering advanced American aircraft alongside the J20. Only by gaining air superiority can fighter jets continue to launch deep attacks. In addition, ground attacks can also be carried out by a large number of hypersonic missiles, as demonstrated by Iran's counterattack against Israel.

Since you are putting onus on the members , here it goes .....circle around the globe without refueling ....minimum speed Mach 5 .... should be able to carry 20 tons of payload....must be classified as fighter not bomber .

India will make it! Because in all seriousness that was my question - what is a good range for this class of aircraft?

 

[Oscar]

Brother, lets ignore "good range" for a minute, you are better than that, and lets talk about what influences range, given similar wind conditions and similar payload.

There are still paper brochure values which help gauge the aircraft - combat range (some will provide mission profile to elaborate)

Hope the J31s will have at least one reverse facing missile on the wing or fuselage so that if there is an enemy plane on its tail the rear plane can easily be shot down by the reverse facing air missile.

Hi,

An alternate is an "EXPLODING AIR MINE" which can be used in close air combat against an aircraft behind---.

Ever heard HIGH OFF-BORE sight short range air to air missile like PL10/ASRAAM/IR-ST/AIM-9X and A-DARTER etc etc, these SRAAMs are specifically designed to shoot down enemy jets behind your jet

When do you figure these unconfirmed performance will be shown to be accurate or not? And after what metric could it be approved for application on the export model?

TWR ratio would have to be similar to the F-35, at least, to match the export potential.
