You are welcome. Chengdu J-20 is more than interesting. It is a game changer. That is a big topic and let's save it for later.
How J-20 compares to F-22 is a question that is on many people's mind. Unfortunately, at this point, other than a few pictures, there has been no technical data released, including geometry (wing span, length, height, wing area, etc.), performance (range, speed, turning rate, etc.), weight/load (empty weight, loaded take off weight, max take off weight, internal weapons load, underwing carrying capability, internal fuel capacity, etc.) and electronics (AESA, IRST, sensor fusion, EW, etc.). All guesses will be just that, guesses. Popularly it is believed that its performance is comparable to F-22 overall but I have no way of confirming or disputing that. However, I am reasonably confident that it should outperform F-35, which is actually inferior to the teen series in terms of speed, agility, etc. because of its dismal thrust to weight ratio and wing load. Believe it or not, it is not that hard to outfly an F-35.
J-20 uses outward canted and all moving twin tails. The purpose of that large amount of deflection is not to enhance maneuverability. However, with that high degree of deflection, it doubles as air brake, together with coordinated moves of flaps and canards, to make sure it slows down level and straight.
Besides that, all moving tails can be more compact, using active control instead of passive stabilization like wind cock. If you look at F-22't tails, you can easily tell the fixed part from the moving rudder at the back edge. The fixed part is that wind cock, resulting from the classic laterally stable design. J-20's smaller V tail is laterally "reduced stability" design, saving on weight and RCS, but more demanding on flight control.
You mentioned that J-20 is similar to F-22. I imagine you refer to the side profile. However, aerodynamics is more determined by "birds eye view" than side profile. J-20 and F-22 are decidedly different from that angle. Aerodynamically, these two are as different as Corvette and Porsche 911, or F-16 and Eurofighter Typhoon.
Hope I answered your questions and nice talking to you.
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.

我也已经修正，谢谢
如果十分之一的年轻人有此信心，中国何愁？zxb就不能在网络上搜集一些这样的帖子广而告之么？
参数变化，作者，声望:1；铢钱:16。你，乐善:1；铢钱:-1。本帖花:1
最同意这句。
几千年，与天地斗，与人斗，造就了中华文明中庸的本质。这城府不是发家三四百年的人能明白的。
我也是一个读者，这篇文章没有完全读完。后面写的的确有此乱，但最后这段仍给了我强烈的共鸣
。泪水涌了出来，花一个。
按数字规律，242团应该在81师吧？
242团的确隶属27军81师，当时加强给80师参加新兴里战斗，任务是阻援。
特别是这句：
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
暴露了隐蔽战线的战士，危害极大，必须尽快删除。

刚才看到了成都网友打印的通缉平可夫的传单，和绝大多数人嘻嘻哈哈的态度不同，我感到很心酸。
老张毕业的大学很一般，但那只是因为他出身的中学环境限制所致，他本人颇具语言天赋，而且很刻苦，当年他能在那批人里面被选派到这个职位，就是因为超强的外语能力和学习能力。我入职时，他已经在外近10年了，但是偶尔几次国内遇到，还是说过几句话的。我们这行通常话都不多，尤其外勤和有公开日常掩护身份的。但老张是名人，即便在我们这个牛人无数的行当里。
05年，我俩意外的在阿布扎比相遇，当时我以参展商的身份四处晃悠，突然遇到老张穿着阿拉伯服饰，带着俩小日本摄影师，正在采访我的掩护公司，我没动声色走了过去，他看见我，目光中一震，我俩谁也没说话，他侧了下身继续用阿拉伯语装模作样的跟人聊着。他走后，我问跟他对话的哥们儿，那人是谁？看着是个中国人怎么说阿拉伯语？那哥们儿轻蔑的说，你不认识他？平可夫，大嘴巴，净埋汰咱们装备，还不说中文，我都想抽他……不过，他阿拉伯语说的倒是真好！这个小哥们儿是北外阿语专业硕士。我点点头，走到一旁，看着老张的背影，感慨万千。第二天，他又来了，我没遇到，听人说，他换了套西装，改说俄语了。
还有什么会比被自己深爱的祖国人民误解更令人委屈的事呢？即便他是个潜伏者。
黑丝出来前，我们内部安排通气会开完，大家就聊到老张，说这次他肯定又该“风光”了。我知道，对他来说，就是压力突然加大了。如何在这中间搞好平衡，既做好本职工作，保持可信度，又不能千篇一律没有创新，但还不能被敏感的敌人抓到破绽，何况，老张对我们的四代期待已久，我怕他会忍不住出问题，即使他是个老战士。
这两天，看到他的发言，我不由得替他捏了把汗，也许是有新任务我不清楚，但如果按照以往的标准来看，他有点危险，态度倾向性有些明显，与以往的他区别较大。但是我理解，作为一个老军工，不激动是不可能的。
那天，双流机场人很多，但我不经过那些地方，一辆普通民用车牌的小车直接等候在廊桥外楼梯下，我按照命令接到了老张。看上去，他几天没有刮胡子，邋里邋遢，还换了副黑框眼镜。我们什么都没有说，就是紧紧的握手。到了地方，我指着二层那个开窗的房间对他说，上去吧，老板在等着你。
他们说了什么我不知道，反正那天晚上，我们都有点喝多了，送老张回招待所的路上，我扶着他，他踉踉跄跄的边走，边哼着那熟悉的旋律，“……要创造人类的幸福，全靠我们自己……”，我紧紧架住他的肩膀不让他倒下，任泪水滑过脸颊，四周无人，只有天上的星星在静静地聆听。
第二天我就回北京了，后来，有同事说收费那天晚上，成都是个阴冷的冬夜，看到老张穿着臃肿的棉服，独自坐在一家小饭店里，面前摆着一碗早已经凉掉的担担面，低着头不停的翻看着无敌兔相机里面的照片，久久无言，也许他想起那天上级首长拍着他肩膀勉励他的话语……看了好久，他收好相机，刚要拿起筷子，却突然双手掩面，大滴的泪水顺着指缝缓缓流下……
祖国万岁！我知道这一定是他当时想说的话。

新加坡太上皇李资政，
以前为了掩人耳目，派老吴出来做摆设，
现在儿子李显龙做了二世，
老婆做了新加坡主权基金淡马溪基金的老板，
钱权都抓完了， 还没有人说他。
他对新加坡有清晰的定位。
东西方交流的桥梁
确切地说是西方剥削东方的桥梁。
