In China, created an ion engine with a resource of more than 10 000 hoursAccording to the Zhongguo Kesue Bao newspaper, the 510 Research Institute of the Fifth Academy of Aviation and Space Concern CASC successfully completed the development of a new type of ion engine with 200 mm grating diameter, which was tested on board the experimental satellite Shijian-9 ) worked continuously over 9 thousands of hours. This is the first ion engine model for spacecraft in China.


Ion engines are actively used to target Russian and American spacecraft from the 1960-70-s. According to the director of the Scientific Research Institute 510, Zhang Weiwen, so far the Chinese have used chemical-fueled engines in the propulsion systems of their satellites, which have made them heavier. He cited as an example a certain satellite that was launched into a high orbit, in which out of 4,8 tons of total mass about 3 tons accounted for fuel. When using an ion engine, the mass savings would be within 2 tons.

SRI 510 began work on the engine in 2007. Its serial use on Chinese spacecraft is expected to begin in 2015.

    Wow! You look after 20 years and the blades for aircraft turbines will master.

      There is no magic in the shoulder blades. It's just that our blades are in our engines, from our metal, with our recipes, according to our processes. If we put, for example, American blades in our engines, then we will suffer for a long time. The main school for turbines, blades and other things was in Ukraine, against the background of recent events, China will not have problems with specialists. It is better to think that the power plants for frigates of Project 11356 are made by the Ukrainian Zorya - Mashproekt, and if everything stops now, hopes for a quick update of the Black Sea Fleet will be a thing of the past.

        ... where does this data come from?!? fellow wassat

        No, I’m still interested ... where do the people get the tales from?

          Invent. Well, okay, since I’m kind today I’ll tell you: in Saloland never did not develop any gas turbine engine, only let out и as yet continue to produce variations of TV3-117, developed by uncles from Leningrad.

            Here, it seems, not for development, but for the establishment of production and manufacturing, with this everything was in order in Ukraine. China has samples, they seek a resource.

          He studied at the easel, faced. Under the USSR, everything was just like that, I don’t know now, but differently, but gas turbine ship power plants are ordered in Ukraine. Conclusions are not difficult to make, all that is needed for production in Ukraine is there, including specialists.

            ... here to do 3-dimensional calculation of the blades are taught in the physics laboratory.
            And only Russians and a little Americans succeeded in this. Therefore, the rest of the world is reaching for us for this ...

              the Americans succeeded only in the fact that in the era of total sacking of the country they were able to maximize technology, although until now curved shoulder blades are doing, ignoramuses!

    Of course, it’s good fellows that the Chinese are progressing, but somehow annoying the thought that one day in labor ecstasy they will launch an orbital station with a nuclear engine (well, like Qiwi) - how to live in anticipation of its inevitable fall ?! belay

      On most spuntiks are RTGs (Radioisotope Energy Sources). In a nutshell, the radioactive substance decays, heat is released which is converted into electrical energy.

        Thanks for clarifying! laughing But I wrote about the engine. The PRC is left to lay down the teikonaut, send something to Mars - and they will catch up with everyone. Then they will start to distill. In terms of technology, it can just be a propulsion system.
