    The J-20's missile is not assisted by gravity. Rather gravity is the J-20's advantage because F-35 has to climb.

    An aircraft doesn't have to be at co-altitude to fight. The F-35's missile can climb faster. It all depends on the superiority of the missile itself during end game rather than during mid course.

    Most BVR missiles, with the exception of ramjet ones, depend on the inertia after initial motor pulse to remain aloft. Missile that has to climb will loose energy at faster rate than a missile that descends (descending missile might even regain some energy lost during the initial climb), and initial energy depends a lot on aircraft's speed; slower the aircraft flies, more energy from the missile itself is required to bring it up to flight speed. So if you have two aircraft with equal, or at least roughly comparable, missiles, aircraft that flies higher and/or faster will achieve longer missile range / better missile performance at given range than slower/lower flying aircraft. Against J-20, F-35 is both lower flying and slower flying. And since J-20 has a ramjet BVRAAM, possible integration of Meteor will not give F-35 much, if any, advantage.

    There is big change in mid body section and tail section. even the canards have been beefed up. have a closer look and you will notice the difference.

    if it looks ugly, it will fly badly. This is a reverse engineered F 22 + F 35 with the canard-wing config.

    Nah! It's a Chinese design for the first time. Yes, some techs from F-22 has been borrowed. But due credit should be given.

    The only innovation i see is a spiked-dsi. Of course there will be innovation when manufacturing is considered. But the layout and planform is pretty obvious.

    The LERX is different as well.

    Sensor have been added in the tail and around the cockpit

    Stealth by structure is not enough to win, it should have so many other features to compete with the best. In my opinion it is just a 4++ gen aircraft with stealth features. Engine and so many other things are substandard. But certainly they can call it whatever they want. If RAM coating and internal weapn bay can make a plane stealth fighter of fifth gen then We can make anything and call it stealth.

    J-20:A Game changer for PLAAF


    [​IMG]
    PLA is undergoing swift modernization and structural changes as part of its ambitious plan to become a formidable military power in the region. The push for indigenisation helped PLAAF to become one of the most advanced airpower the world. After closely studying strategies of Falkland wars and Yom-Kippur wars, china made the significant change to combat strategies. They realized the need for building new aircraft that would possess long ranges and larger weapon carrying capacity. The J-20 was developed as part of J-XX program which started at late 1990's.
    On 22 December 2010, the first J-20 prototype underwent high-speed taxiing tests outside the Chengdu Aircraft Design Institute.It was first flown on 11 Jan 2011, just 2 days after the US secretary of Defense Robert Gates started visiting China. Although they claimed test was preplanned, most observers believe that China was intended to send a clear message to the west about it's growing military capabilities. In 5 years Chengdu Aerospace Corporation made a total of 9 prototypes with the latest prototype rolled out on Dec 2015. The latest prototype, which marked as 2101 suggests that it would be the first among Low Rate Initial Production airframes (LRIP), which is intended for military use. It signals J-20 may enter service before planned induction date.

    [​IMG]
    J-20 Design is largely based on F-22 and canceled Russian fighter MiG 1.42. The Chinned nose cone and canopy have close resemblance with that of F-22. The fuselage and tail structure is almost similar to that of Mig 1.42 and YF-23 respectively. It was the first stealth aircraft to feature a large dihedral canard and a delta wing configuration. There were lots of debates regarding the use of canards and stealth capabilities of aircraft. Though CAC claims to be using a low RCS canard structure, experts believe that this may result in reduced stealth capabilities. As the material breakdown of J-20 is not available, some studies indicate that it may have titanium body rather than composite materials. The material used plays key in modern fighters as they have to withstand the large heat generated by sustained high-speed operations. At the same time, composite materials and surface coatings help in reducing radar signature.The trapezoidal edge aligned engine inlets are closest to F-22, though appear to be larger and would employ F-35 style Diverterless Supersonic Inlet (DSI), which will improve inlet edge signature. Larger DSI also implies the use of bigger engines.

    China faced major setbacks in developing an engine for the J-20 program. As its design demands more thrust to weight ratio, which is around 10:1, the Russian-supplied AL-31 will affect its capabilities. As AL-31 is supposed to power Su-27, the supercruise capabilities of J-20 would be limited. The performance of J-20 will largely depend on future engine developments. They have to develop an engine, which will have similar performance that of Pratt&Wittney F-119/W-15. The Initial production series would be powered with W-10/AL-31F engines and later production series might be powered by W-15 before induction.
    The J-20 also carries a powerful active electronically scanned array (AESA) radar, nose-mounted infrared search and tracking sensors, and fuselage-mounted cameras to give its pilot a VR 360 degree imaging (similar to the F-35's avionics). For weapons, the J-20 would have long-range missiles like the PL-12, PL-15, and PL-21, and short-ranged infrared-guided PL-8 and PL-10. Networked with other platforms such as the Divine Eagle anti-stealth drone, the J-20's array of sensors will give it the ability to go toe-to-toe with other stealth fighters. China claims that J-20 would be ahead of its Russian counterpart T-50 in terms of Avionics.The aircraft features a glass cockpit, with two main large color liquid crystal displays (LCD), situated side-by-side, three smaller auxiliary displays, and a wide-angle holographic head-up display (HUD).A revised nose section, much similar to that of the much-criticized F-35, with an IRST/EOTS (Infra Red Search and Track / Electro-Optical Tracking System) – used to hunt low observable aircraft and a metal finish that loosely reminds the radar absorbing Haze Paint first used on F-16s

    Based on Design and Avionics J-20 could be used as a long-range interceptor and as a strike fighter. As J-20 possesses a larger internal volume, it would have the capability to carry more fuel and an array of weapons.This will enable it to shoot down AWACS and Tankers of enemy forces as well as act as a long range interceptor. The design along with suitable armaments would enable J-20 to function a Theatre Strike Fighter, Electronic attack platform or even as an Anti-Satellite Weapon Launch Platform.

    China to unveil its J-20 stealth fighter at air show

    BEIJING: China will unveil its new generation J-20 stealth fighter jet at an air show next week, the air force said on Friday, the first public showing of a warplane China hopes will narrow the military gap with the United States.

    The ability to project air power is key for China as it takes on a more assertive stance on territorial disputes with neighbours in the East China and South China seas.

    The Pentagon has said the fifth generation stealth aircraft China is developing, the J-20 and the J-31, are necessary for China's air force to evolve from a mostly territorial force to one that can carry out both offensive and defensive operations.

    The J-20 will give a flight demonstration at next week's China International Aviation and Aerospace Exhibition in the southern city of Zhuhai, the People's Liberation Army Air Force said in a statement on its official microblog.

    Air force spokesman Shen Jinke said the J-20's production was proceeding according to plan and would assist in the air force's mission to "safeguard sovereignty and national security".

    "This is the first public appearance of China's indigenously manufactured new generation stealth fighter jet," the air force said.

    In June, it said the jet would enter service "in the near future".

    The new Y-20 military transport aircraft will also give a flight demonstration at the seven-day air show, which is held every two years and opens on Tuesday.

    China showed off the J-31 at the last Zhuhai air show in 2014, a show of muscle that coincided with a visit by U.S. President Barack Obama for an Asia-Pacific summit.

    China hopes the J-31, still in development, will compete with the U.S.-made F-35 stealth aircraft in the international market, according to China military watchers and state media reports.

    Some analysts have said photographs of the J-20 suggest China may be making faster-than-expected progress in developing a rival to Lockheed Martin's radar-evading F-22 Raptor.

    But others say China's defence manufacturers are still struggling to develop advanced engines that would allow its warplanes to match Western fighters in combat.

    Beijing has been ramping up research into advanced new military equipment, including submarines, aircraft carriers and anti-satellite missiles, which has rattled nerves regionally and in the United States.

    China says there is nothing unusual about its development of military technology, and that it is a reasonable course of action for every country that wants to defend its security.

    In this infographic, I have covered the stealth features present on the top-side of the Chinese Chengdu J-20 stealth fighter. Also, I have covered some of the stealth features present on the side of the Chengdu J-20. Later, I will create an infographic to cover the stealth features present on the underside of the Chengdu J-20.
