China's Space Program Thread II
- Thread starter Blitzo
- Start date
I think they are reusing a lot of the tooling and machinery of the LM5 rocket as both are 5 metres diameter, so there is a limit to how many you can fit. It was originally 5 engines but they changed the propellant pumps of the YF-100 so that they could fit in an extra 2 engines in. The LM10 is good enough for now and will be soon ready for testing.
YF-100k is slightly uprated and has the gimbal system redesigned to allow this clustering (max is 7 for 5m). Since it's the next crew launcher they need mature technology not a completely novel design. Tooling is inherited from the CZ5.
Lots of interesting info here
The most important thing is this rocket actually targets dry mass margins and technologies beyond current Chinese state-of-the-art.
They have done a lot of optimisation for dry mass for this new rocket, which was something they really needed to work on to improve previous poor chinese rocket dry mass, incl:
- cold-pressurized gas cylinder compatible with liquid oxygen
- COPVs
- new pumps and and more compact TVC system
A very important step towards CZ-9.

General
The carbon-fiber composite fairing for Zhongke's Lijian-2 launch vehicle has rolled off the production line. The fairing has a diameter of 4.2m and a length of 12.19m.
Zhongke/CAS Space has successfully completed a stage separation test (1st and 2nd stage) for the Lijian-2 launch vehicle.
