Chineese 5XX fighter test flight?

[conworldus]

People. By the time official news of test flight comes out, J-XX would have already been inducted. This is the Chinese way. The news come out years after. Same thing with J-10, T-99 tank, etc.

-XX[2] J-X,[2][3] and XXJ[2] are names applied by Western intelligence sources to describe program(s) by the People's Republic of China to develop one or more fourth[3] (by Chinese nomenclature) or fifth-generation fighter aircraft (by west).[2] 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.[4]

History

In 2002, Jane's Defence Weekly reported that Shenyang Aircraft Corporation had been selected to head research and development of the new fighter,[3] a claim repeated in New Scientist the same week.[5] However, a 2006 article in Military Technology referred to three designs; two by Shenyang Aircraft Corporation and one by Chengdu Aircraft Corporation.[2]

According to the report from Jane's, development of the subsystems, including the engine and weapon suite for the next generation fighter, has been under way for some time. A photograph of a wind tunnel model published with the article showed a twin-engine aircraft with twin vertical tail fins. The article text mentioned that the aircraft would carry its weapons internally like the F-22 Raptor. New Scientist called attention to the angular, faceted features of the design, comparing them to the F-117 Nighthawk. Jane's also linked the programme with China's development of an engine with thrust vectoring capability.

The later report in Military Technology featured a picture of a completely different design, speculatively dubbed J-14 and said to be a Shenyang project, with the designations J-12 and J-13 being applied to (possibly competing) designs by Shenyang and Chengdu respectively.

In November 2009 He Weirong (何为&#33635, deputy commander of the Chinese air force, confirmed that "intense" research and development work on the fifth generation stealth fighter was ongoing. Being developed by Chengdu Aircraft Corporation and Shenyang Aircraft Corporation, the aircraft has not yet been given a designation but is expected to be unveiled within the next 5 years and would enter service by 2015, according to Weirong.[4] Another source quotes Weirong as saying the aircraft would enter service within 8 years, giving possible in-service dates of 2017 to 2019.[6][7][8]

A U.S. Defense Intelligence Agency official commenting on Weirong's claims stated the DIA believes a first flight of the J-XX "will occur in the next few years", but it is also believed that operational deployment of the fighter "in meaningful numbers" will not take place "for about 10 years."[9] U.S. Air Force and U.S. intelligence officials have stated their belief that China likely has all the resources, data and technology required to build a fifth generation fighter. However, doubts remain on whether China has enough knowledge in areas such as systems engineering, integration and production processes to build a fighter comparable to U.S. stealth designs which can also be produced in large numbers. It is speculated that the fighter may not be an "all-aspect" stealth design by some sources, for this reason.[10] The U.S. Department of Defense expects China to have a handful of fifth generation fighters in service between 2020 and 2025, according to statements made by U.S. Secretary of Defense Robert M. Gates in July 2009.[11] However, a year later, in May 2010, this statement was rebuffed by the US' prime intelligence producer -- Ulman stating that Chinese 5th generation fighter jets will be expected around 2018.[12]

Design

The general design concept of the J-XX is that of a fifth generation fighter which incorporates stealth, supercruise, super-maneuverability and short take-off capabilities, abbreviated "4S".[13] One or more of the proposed designs are believed to incorporate several design features for increasing stealth and maneuverability while decreasing weight and drag.

A V-shaped pelikan tail could be implemented, replacing conventional vertical tail fins and horizontal stabiliser structures. This would be beneficial for reduction of radar signature, weight and aerodynamic drag, since control surface area and corresponding control mechanisms are reduced. Problems faced by this type of design are flight control system complexity and control surface loading. If the pelikan tail is adopted, use of engines with thrust vector control may alleviate these problems.[14]

The new fighter may have a significantly longer fuselage than other fifth generation fighter designs, such as the F-22, for reduction of transonic and supersonic drag.[15] A trapezoidal wing may be implemented for reduction of drag and radar signature.[16] Use of an 's'-shaped air inlet and boundary layer separation system would greatly reduce radar signature.[17]

So i think we have to wait for another 15 or more years cause till now China struggling in J10B from years

Engine still in progress even your own chief admit in 2009 quality of engines not as pr stndard

Aesa??
Stealth feature ??

Making a 5th gen fighter in not a joke

Wrong information you have...

 

[ChineseTiger1986]

China did not build those mega petaflops computers just to show off.

Wrong information which one ????

Engine ? you need source ??

china's 5th gen is no where near it has to develop a powerful AESA radar,a jet engine capable of supercruse and 3dtvc...and stealth materials and china is in medium state in everything...it has not yet perfected in the WS-10a engine and that is not in complete production.......

That's what the CCP wants us to think.

Buddy China still importing Russian engine.

And here we are talking about engine for 5th gen fighter. just think again

when was the last time china order AL-31

early batch will equip with modify WS-10 or 99M2 which could offer around 14 tons of thrust.if WS-15 program goes smoothly, jXX will equip with it around 2020

these two type of engine are both qualified as transitional choise,just read my post again.

 

[Man of Thoughts]

As far J-XX is concerned it will surely come out in near future thats what i believe...

Well that surely come out in future no buddy can deny that but some fan boy think that Jxx will come out at the same time with PakFa or with in 2-3 years after PakFa.

 

[news]

In these months, some "no obligation" site will have J-XX prototype photos appeared.
The key is you can not find this site.

1. Radar, China is ahead of the so-called medium state. An AESA is likely being tested on J-10B.

2. 3D TVC, China had been testing a TVC WS-10 variant during Jiang Zeming's reign. Supercruise is not a critical parameter and is only included in the criteria of a 5th generation fighter as a marketing scheme. Having a fraction of a mach more isn't going to make much of a difference. Are you going to neglect the significance of stealthy aircraft flying at 1.4 mach? WS-10A is in mass production. The quality issue frequently quoted by Indian posters are issues that arise from mass production which require a high tolerance, meaning that by that time, the engine was already entering it's final stage of production. The quality issue has been solved as of now.

3. With respect to stealth materials, that's your conjecture.
