vladaa012 ::Nije mi jasno u kom pravcu ce da vektorise potisak!? Bukvalno je zarobljena u svim pravcima osim na dole. Da nije ovo test stelt mlaznice za J 31?
Ne okreće se cijeli stražnji dio mlaznice nego se pomiče tek završni dio mlaznice. Određene vanjske latice se šire, počevši od prstena pa prema straga, te time daju prostor unutarnjim laticama da se orijentiraju u potrebnom smjeru.
We were lucky enough to speak to pilots who have flown jets equipped with thrust vectoring nozzles (TVC) to get their opinion of the J-10B flight demonstration at Zhuhai airshow.
It was clear that the nozzle did vector downwards but only for a small degree. The minute deflection was enough to generate the lift necessary to keep the nose up during the pass. The angle of attack was between 20-30°. Even during the cobra maneuver, not much deflection of the nozzle is necessary to execute the classic move.

Citat:Analysis of J-10B TVC demo at the opening of Zhuhai airshow
The J-10B TVC demonstrator finally made full use of its thrusting vectoring nozzle during the opening display at Zhuhai airshow 2018
The aircraft climbed after takeoff to perform a TVC loop. Returning back to show center, it did a spin roll.
It then return to show center to climb and execute a loop tumble yaw maneuver. Some mistaken this as falling leaf maneuver.
The pilot then executed the first cobra followed by a J-turn at high altitude.
The last maneuver was another cobra done at a lower altitude. Compared to the Russians, the Chinese version of the cobra was less than a second shorter as the pilot quickly pushed the nose down for recovery.
Foreign pilots who have performed the cobra at airshows praised the flying display sequence of the J-10B TVC after watching online videos of its display.
The aircraft also demonstrated its full use of the TVC in all three axis.

Eto ta slika je upravo prikaz o kojem sam pričao. Hvala što si se potrudio pokazati je. Dakle mlaznica se ne okreće cijela nego se jedan (veći dio) mlaznice samo širi ili skuplja, i to nejednako. Npr jedan dio latica mlaznice ostaje raširen dok se dio latica nasuprot njemu skupi. A završni dio mlaznice ima pomične latice koje se onda još dodano pomiču i lijevo i desno, po potrebi. Sve to omogućava unutarnjim laticama (koje su otprilike dužine kao i vanjske latice) da se odista orijentiraju u svim potrebnim smjerovima. Uglavnom, možda je moguće da vektor potiska nije baš jednako izražen kao u nekim drugim motorima/avionima, ali se ovo svakako čini kao jedno elegantno i moguće ne pretjerano teško (po masi) rješenje.
