China's New Generation Manned Rocket(921 rocket)

The design of the rocket is derived from public information on the Internet, and some personal ideas have been added to optimize it. The shape design of the spacecraft is derived from the experimental spacecraft of China's new generation of manned spacecraft (CZ-5B Y1 mission).

The first and second stages of the rocket use liquid oxygen kerosene fuel (LOX/RP1), and the third stage uses liquid oxygen and liquid hydrogen fuel (LOX/LH2). The rocket adopts the CBC configuration, the core stage and the booster are common (the core stage engine is throttled), and the booster can be recovered and reused. The rocket can deliver 25 tons to low lunar orbit, or 75 tons to LEO. When four boosters are used, a load of 25 tons can be sent to the Earth-Mars transfer orbit (you need to set the version in the Detacher property of the side interstage of the booster to 2 in the XML editor).

The spacecraft is designed with two compartments: the return cabin carries three to seven people, and can dock with the lunar low-orbit space station or lunar lander; the propulsion module can complete near-month braking (the backup of the third stage of the rocket), lunar orbit docking, and moon-Earth transfer Incident and orbital maneuvers.

Activation groups:
AG1: The spaceship's return module and propulsion module are separated, and the RCS switch of the return module.
AG2: The parachute of the reentry module.
AG3: Throw insulated outsole.
AG4: The landing buffer airbag of the return capsule.
AG5: The hatch of the return cabin.
AG6: Protective cover for the docking port.
AG7: The hatch of the docking port.
AG8: The landing legs of the propulsion module.
AG9: Solar panels.
AG10: RCS of the propulsion module.
AG11: Back to the cabin lights.
AG12: The ion engine of the propulsion module.
AG13: The main engine of the propulsion module.
AG14: Open/fold antenna.
AG15: A switch for the antenna to automatically point to the target.
AG16: Expend/retrieve the screen in the return pod.
