[China's best pupil: Part10] North Korea's Unha-18 Manned Space Launcher
China's CZ-2F Manned Space Launcher
▲ 发射“神十”的长二F火箭
▲ 长征二号F运载火箭在研制中
▲ 神舟七号飞船上方小卫星。
▲ 长征二号F火箭垂直转运。
▲ 2008年9月25日21时,神舟七号飞船满载国人的希冀一飞冲天。
▲ 长征二号F(CZ-2F)由中国运载火箭技术研究院研制,是在长征二号捆(CZ-2E)火箭的基础上,按照发射载人飞船的要求,以提高可靠性、确保安全性为目标研制的运载火箭,可靠性超过97%(置信度0.7),是目前我国现役运载火箭中起飞质量最大、长度最长的火箭,主要用于发射神舟飞船和大型目标飞行器到近地轨道。
火箭全长58.4米,一、二子级直径3.35千米,起飞质量约480吨,可以把8.8吨的有效载荷送入近地点200千米、远地点350千米、倾角42°的地球近地轨道。
Following are some of the major facts and figures about Shenzhou-5 spacecraft
1. The spacecraft was 8.86 meters in total length, and weighed 7,790 kilograms;
2. Its re-entry module, with a diameter of 2.5 meters, has a volume of six cubic meters;
4. Fifty-five latest technologies were used for the first time to build the Long March CZ-2F carrier rocket that sent Shenzhou-5 into space;
5. The rocket had a liftoff mass of 479.8 tons, and the rocket and the craft atop it measure 58.3 meters in height;
6. Shenzhou-5 flied a circular orbit 343 kilometers over the Earth after the orbit shift;
7. It took about 90 minutes for Shenzhou-5 to make a single circle round the Earth, and it stood the test of a temperature gap as great as 180 degrees centigrade in orbit;
