China's Space Program Thread II
- Thread starter Blitzo

I always wondered how they would design the elevator cables that can withstand collisions and impacts from all those high-velocity space debris and space garbage that are orbiting the Earth right now?Some screen captures of an exploratory paper on a space elevator design. Does anyone have access to the paper?
The source to these diagrams seems to actually come from three different papers, their copies can be found .
As potential further reading, is a relevant 2022 paper that reviews and updates some of the earlier findings (the 3 papers above are 2015-2018).

Construction on a new high-thrust engine test bench in Tongchuan (铜川) is making good progress. Concrete pouring for the phase I of the project is complete. The new test bench will be used to test the 500-ton YF-130 engine for the Long March 9, China's upcoming super heavy carrier rocket.
Phase I construction of the new engine test complex is almost complete, during which two test stands will be built. Right now, equipment installation and testing are underway. By the first half of this year, the facility is expected to carry out an initial test of the 500-ton YF-130 engine for the Long March 9 rocket.
Images below depict the installation of two 100-cubic-meter cryogenic oxygen tanks. Each tank weighs 70 tons and is 17m tall and 4.2m in diameter.
