家园 咳咳。。英语回复，不然人看不懂 谢谢啊～～
家园 回答很简单 Hey pal，
back to do some homework first before you ask such basic Qs regarding the mechanical soundness. Simply watch the airshow videos to see how your almighty F22 make high G maneuvers with constant moves of its horizontal tails. It's also a single piece fin similar to J20's vertical tail.If it is not ripped off on F22, why should be J20's? You may concern on other aspects of the aerodynamic design, but to challenge such a mechanic 101's sounds to make the point not from a qualified military professional.

家园 转达一下 First, I may not be a military professional (not yet at least) but I have done my homework. For instance, the horizontal tails that you mentioned are elevators and are on every airplane and they must move in order for the plane to fly. What I was talking about is the vertical stabilizers, of which there are two on both the J-20 and the F-22, not one.
In addition, I didn't praise the F-22 over the J-20 at all. I had such basic questions because they were a point of debate between myself and my friend. I'm sincerely interested in the questions I had and I'm not trying to force any agenda. Perhaps you should read what I wrote instead of reading into it and making me sound aggressive.

家园 more answer Mechanically, all moving vertical tails and all moving horizontal tails are identical. So the "rip off" problem is non-issue. As I mentioned separately, such large deflection is not used for air combat maneuver, it is used as air brake. The fly-by-wire will limit the angle of deflection during maneuvering flight for all sorts of purposes, mostly for aerodynamic reasons, but also mechanical integrity. Twin tail can do many tricks that a single tail can't. If you are interested, we can talk more. On the other hand, there is no need to be modest about F-22. It is the best manned fighter, bar none, except maybe, just maybe, against J-20, which we have no credible data to compare against so is a moot point right now.

家园 张局长后继有人了 杜文龙副局长，孟祥青副局长，都是很有前途的大校，看他们两个谁完成任务更出色，谁就可以挂上将星，将来接替张局长。目前看，他们和张局长的水平都有差距，在媒体上还不能做到收放自如
两位副局长要努力哦
家园 想当初在电视上 把咱因为副司令爆料燃起来的那点小希望说得灰飞烟灭的,好像也有他一个把.现在也开始一本正经的开聊J-20了(你咋不说是J-10DG呢?)脸不红心不跳的,和电视上那些股票专家一样,虽说是
"奉旨"(也不知道是不是真奉旨,公测说是姑且就算是吧),但总这样搞说话也就没有Credit了,谁知道你这次是不是又在"奉旨"吓唬俺ne...
家园 这是什么概念？ 不是金属或不完全是金属……
难道整个机体都是复合材料？

家园 刚发现T50也是全动小尾巴 家园 正是，战斗机中，就看到T-50和歼-20是全动垂尾 F-117不大好算，那是无尾布局的V形尾，兼做平尾用的。连民航客机都全动平尾了，F-117不全动就不好意思见人了。
