Where is deino? We need his expert explanantion on AL-31 engine in J-20.
I have long indicated of domestic engines used on J-20 in 2014 not becos I am nationalist or biased but based in simple facts like
-no Russian media indicating any cooperation in installing Russian engines for J-20 project unlike the J-10 project.
-PLAAF deputy chief indicate super cruise is a must for J-20 to be inducted for combat operation. PLA has display great professionalism in their announcement for any news and operation requirement( they never brag or make willful dateline and claim)
-high ranking CPC members like Yingzhuo mention about domestic engines used on J-20
But yet some foreigners has just too much ego to accept the fact Chinese 5th gen fighter used a domestic engine while make unsubstantial claim that appearance of just a few engine petal is the best proof of j-20 using Russian engines. Then they even claim they are aviation expert?
