(1) Tiangong 1 weighs merely 8.5 metric tons (hereafter tonnes). Besides
Tiangong 1 on Sept 29, 2011 Long March 2F also launched Shenzhou 5 (in 2003)

From Huitong
The J-20 #2001 prototype was photographed when it was preparing for high-
speed taxxing trial at the CAC airfield on December 22, 2010. The prototype
features a pair of all-moving tailfins and ventral stabilzing fins, and the
laters are expected to be removed on the production models. It also features
F-22 style air intakes but with DSI bumps installed at the upper corners,
as well as a one-piece canopy. First disclosed by US Office of Nav... 阅读全帖 |

88年中国核潜艇项目下马,一下就是20几年太可惜
太可惜:从094看中国核潜艇研发的断点
云淡水暖
核潜艇作为战略威慑武器,无疑代表了一个军事强国的核对抗实力,或者常规局部战争
的海上打击能力,去年美国在南海、黄海亮肌肉之前,还把弗吉尼亚号核潜艇派到南海
周边公开“停泊”到某国的港口,让记者狂拍。所谓“三位一体打击力量”,核潜艇是
不可或缺的一个方面军。国产“094”的在各大军事网站和相关军事媒体的出现,令中国
军迷和网民倍受鼓舞。最近,草民看到一篇文章,2004年12月下半月刊《现代舰船》上
刊登的访谈录“龙啸九天——中国核潜艇专家采访录”,这位老专家叫做黄旭华。

The listed payload capacity of 10,000 kg LEO for GSLVIII should be assuming
a fully functional 3rd stage. It's 20% smaller than LM3B's listed 12,000kg
LEO payload. |

It was reported in November 2006 that a T/W=10 17,000kg class turbofan (WS-
15/"large thrust") is being developed for J-20. This new engine is currently
scheduled for testing on J-20 in 2015. |

糖高粱(学名Sorghum bicolor (L.) Moench,英文sugar sorghum)也叫芦粟、芦穄、
芦黍、芦稷,甜秫秸、甜秆、甜高粱和高粱甘蔗,为粒用高粱的一个变种,它同普通高
粱一样,每亩地能结出150-500kg的粮食,但它的精华主要在富含糖分的茎秆,其单产
可达5,000— 10,000kg每亩。甜高粱茎秆可用于制糖、酿酒、制酒精燃料、造纸和饲料
等。巴西有芦粟酒生产。 |

看来含金量高的还是Cayenne啊。如果4400lbs外加更低的车身,操控又更近一步向
Performance Sedan靠拢了。
-- Drop below 2,000kg(4,409lbs)
-- Top speed of 186 mph (300 km/h)
-- Turbo/Turbo S powered by a newly developed V8 turbo
-- Much quicker(even compare to new Turbo S which is already capable of

x*b 发帖数: 5723 | 13 但是就目前的消息来看,Porsche对下一代Cayenne信心很大。将会是业界这个级别第一
台原厂量产车能跑到300km/hr,然后Ring speed在7:50秒左右。

要知道这可是一台SUV。
