Web user’s 6 connected photos of J-20’s boosted climbing

The above set of 6 connected photos describe the moment when J-20 has started its booster to climb up. The deflection of the canard and the large amount of vortex flow prove J-20’s wonderful pneumatic design.

The six photos are shown separately below on the deflection of canard and vortex flow in the moment:

    Whoever made the photo must enjoy taunting the American stealth designers. The still pictures of the J-20 climbings show how smooth the plane climbs without causing significant atmospheric ripples, thus reducing the effect of sonic boom. Stealth is not just about evading radar. The ability to control sonic boom is another important feature. That’s why thrust-vectoring is featured so importantly for the failed F-35. But the J-20 in the picture doesn’t appear to have thrust-vectoring. Still it achieve what the F-35 failed to do. Must be one heck of an engine thrust, considering the J-20 is huge. Sure the American would go to classic tactics of accusing China of ‘hacking’ F-35 designs. But who would steal a scooter design to build a racing motorcycle? In the meantime, the American will continue the propaganda that J-20 cannot beat F-35/F-22 that only the American will stupidly believe and the Chinese will continue to show the American the progress of J-20 that only American stealth designers understand. These pictures of J-20 progress should be top secret, which he American will go through dirty espionage at any cost to obtain them. Instead, the Chinese gave them away for free. It shows how confident the Chinese is that the American will never catch up. It may also reduce the potential of damaging and troublesome American espionage attacks.

    I think its both hydraulic systems and pneumatic design for noise control and motion.

      One thing for sure and that is the J-20 is a very BIG airplane and may not perform very well against a more agile peer in WVR combat. I was looking for more maneuvering in the vertical during the recent airshow and didn’t see any. What say you?

        AS regards an agile peer against the J-20 in WVR combat, unfortunately, my knowledge is limited. The latest news is that the J-20 won 10 nil against the J-11s in friendly combat and will be interesting against the Russian SU-35 recently, delivered to PLAAF. The J-20 is designed for air supremacy and counter offensive against enemy aircraft and warships. The Russians believe that the J-20 will force the US aircraft carriers into an impasse. The J-20 main task is to seize air superiority to intercept the US long range strategic bombers, early warning and reconnaissance aircraft. According to reports, a regiment of J-20 will effectively eliminate US main space based reconnaissance within a radius of 1600 – 1900 km radius and reducing the efficiency of US carrier battle groups outside Guam borders.

        The J-20 has no problems in BVR combat radius with PL15 missiles that can be launched further than the US. As for near peer WVR combat, there is the possibility of US F22 and Russian SU35. The French Rafale jet.? Your guess.
