Re: china manned space - news and views
not sure if this is the right thread to ask the following question:
I'm a big fan of the Russian NK-33 rocket engine which uses oxygen-rich preburners to drive the turbopumps, the NK-33 is extraordinarily lightweight with thrust-weight-ratio at the incredible level of 133, almost twice as efficient as the space shuttle's main engine.
my question is: outside of russia, has any other country ever developed the technology? in particular does the first stage of china's new Long March-5 use the same tech?

China Studies Moon Rocket

China is studying the design of a Moon rocket in the class of the Saturn V, as the Obama administration proposes canceling the U.S. successor to the Apollo launcher, Ares V.
The country also is developing another new rocket, the “medium thrust” Long March 7, the China Academy of Launch Vehicle Technology says. This new launcher joins the Long March 5 heavy rocket and the Long March 6, which was mentioned last year and is now defined as a “small-thrust” launcher. Long March 5, 6 and 7 will form a family of rockets, it says.
Chinese space officials have said that the Long March 6 was based on the side boosters of the Long March 5. Those side boosters come in two sizes, which could be arranged variously as first or second core stages or as boosters. Long March 7 is therefore likely to be a more powerful combination of the same collection of equipment.
China said last year that development of Long March 6 had begun and that it would appear in 2013, a year before Long March 5.
The Long March 5 has a core diameter of 5 meters (16 feet) with boosters of either 3.35 meters or 2.25 meters, officials say. The 3.35 meter diameter, the same as that of the original Long March series (Long March 1, 2, 3 and 4) was chosen as the largest that would fit within the loading gauge of the Chinese railways, one program executive told Aviation Week last year. Established tooling could also be used with the 3.35 diameter booster, even though the materials and structural design would be different, that executive said.
But the facilities of the space industry base under construction at Tianjin will be adaptable to handle rocket diameters of 8 or even 10 meters, an official there said last year, hinting that the plant was prepared to build an equivalent of the Saturn V, whose first-stage diameter was 10.1 meters.
Confirming that such a Chinese Moon rocket is at the study stage, the vice-president of the China Academy of Launch Vehicle Technology, Liang Xiaohong, says it will have a thrust at lift off of 3,000 tons. The Saturn V’s S-1C first stage generated 7,648,000 lb. (3,470 metric tons) of thrust at sea level.
Liang says the payload of the Moon rocket has not been defined, which seems to suggest that the achievable launcher technology will determine the scope of the mission, rather than the desired mission determining the performance of the rocket.
The Chinese government has not authorized a manned Moon mission, but it is clear the country’s space sector is at least being allowed to prepare for one.
The latest announcements have been reported by Xinhua news agency and the China Daily, an English-language newspaper whose content is intended for foreign consumption.

Good News. Heavy duty boosters are needed to travel to the moon. I am hoping that China sends a woman astronaut so that China will still get First woman on the moon lol.
