For those of you who say that the big size of the J-20 makes it less
manoeverable than the F-22, i say that 5th gen fighters are not supposed to
be dogfighters, so manoevrability is not an issue because BVRAAMs will
decide the fight in future wars as well as AESA radars. I have provided a
link to a site that will give more insight, perhaps.

Russia’s new T-50 stealth fighter is fast, maneuverable, heavily-armed and

But according to Indian air force officials, in practice the Sukhoi-made
stealth jet is also too expensive, poorly engineered and powered by old and
unreliable engines.
The Indians’ complaints illustrate the yawning gulf between stealth
warplane design and the actual production of radar-evading jets. In other

空中优势战斗机的的前置鸭翼设计就是鸡肋,为了提高机动性而舍弃隐身、超巡等重要指标,前置鸭翼的设计J20是最失败的代表,相比之下T50的前置鸭翼确是最成功的代表,而我们的军工确没有这样的思路,最令人厌烦的是:已经明显是事实情况之下,自以为是的人太多,骄傲狂妄之徒太多,井底之蛙之人太多,这样的情绪蔓延会严重影响我们的决策者。
前置鸭翼,头部阻力增大,怎么超音速飞行?增加多少阻力?浪费多少航油?战机头上的铁帽子如何实现静稳定?歼20脑袋上订了个铁帽子压抑还说是机动?你脑袋上带个铁帽子机动给我看看?

如何才能不去顾忌J-20 原创翻译完工 Bill Sweetman 新博文和相关评论 更有深度
昨天翻译了一篇有关J-20的Bill Sweetman的博客和相关评论《成都的迷雾消散中》,
反应不错。
年底正好不忙,今天再翻译一篇他新的博文和评论,早上看过一遍,觉得更有深度。
首先是Bill Sweetman空间上的本人介绍,当然是业内专家。
他的看法可能比我们的一般专家贵宾要更有价值。

US stealth bomber as messenger: what it says to China, North Korea
The Pentagon sent its distinctive bat-wing-shaped B-2 stealth bombers flying
low over the Korean Peninsula this week – dropping munitions over a remote
South Korean island – in what US military officials initially described as
a routine training exercise.
But the B-2 bomber runs – along with the US military’s unusually frank
announcement of this fact – were designed to send a far more pointed
warning to North Korea, and more prec... 阅读全帖

来自主题: TVGame版 - MW3 出新的游戏模式了
其实说道想要升级快,我在youtube发现一套挺好的:
support : ballistic vest--》》Recon Drone--》》stealth bomber
最后一个是我自己改的,因为我实在是太喜欢stealth bomber了。不要stealth bomber
加一个sam,可能升级更快一些。
一定要升的高一些recon drone,每点名一个好像是25还是20来着,被点名后,再被杀
死,你好像还会有25分。也就是说,如果是ground war的话,我一次recon drone拿个
500xp,就是个均值。。。

来自主题: SciFiction版 - Science Fiction Novels in 2011
2011 is shaping up to an amazing year for Speculative Fiction at large not
just Fantasy although that is looking damn good all by itself. My Sci-Fi
list last year was only 7 books long, which grew a little with the year, but
it was so short I combined it with UR and Steampunk picks. This year Sci-Fi
warrants a post all its own with loads of debuts and returning stars. The
people claiming Sci-fi is dying or already dead should shear the wool off
their eyes and see what is brewing.

Imagery emerged on the Internet last weekend showing China’s latest stealth
fighter in prototype form. With fifth-generation characteristics, it bears
a distinct resemblance to the Lockheed Martin F-22A Raptor and F-35A/C
Lightning II stealth fighter designs, and appears to be similar in size to
the latter. Photos of the twin-engine aircraft on the ground at an
unidentified airfield–possibly Xian-Yanliang airbase–were leaked the day
before U.S. Secretary of Defense Leon Panetta started a three-d... 阅读全帖
