F-20 warplanes New Year photo: Last vents reveal a big mystery vibration foreign media

LONDON, February 12: Recently, published online by the photo of an F -20 fighter demonstrator attracted media attention, in this photo, two F -20 fighter engine vents convergent flap showing different colors which side of the convergent flap with Russian-made AL-31 series engine, some analysts pointed out that the F-20 fighter demonstrator may use Russian-made AL-31 engine as the driving force, after some foreign media speculated that the use of domestic "Taihang" engine.

Some analysts believe that the F -20 fighter AL-31 engine, a more prudent strategy may be equipped with the stealth of a white jacket outside of the engine tail pipe, used to reduce the radiant heat of the engine indicators. From the figure, we can see the small figure following engine tail pipe convergent flap appears blue, different from before.

Taihang engine end vents, the outer layer of the convergent flap turns overlying structure, each piece convergence are both linked to the part of the adjustment piece laminated front a body, tail vents in appearance by the size and shape convergent composed of slices.

AL-31 engine tail vents outer convergent flap every two convergent holder a small convergent flap structure, in appearance, a large convergent flap and small convergent flap interleaved to form a circular tail vents .

"Taihang" engine and AL-31 engine vents convergence significantly different structure and shape of the flap, under which you can easily distinguish between the two, whether the discriminant fighters have been loaded on the "Taihang".

Last vents thumbnail "Taihang" engine, the outer layer convergence adjustment piece is in turn laminated structure, and each film laminated front a body, tail vents in appearance by the size and shape convergence adjustment part of the chip are connected end to end convergent flap composition.
