The low-temperature propellant filling and venting test of Zhongke Aerospace's liquid launch vehicle has achieved complete success
In early April, the liquid research and development team of Zhongke Aerospace successfully completed the low-temperature propellant filling and leakage test in the innovation center laboratory. This test is a comprehensive test that combines the ground filling system and the rocket storage tank system.
The propellant filling system is an important component of rocket ground equipment. Its function is to add and release propellant to the rocket, transport and store propellant, and treat or safely discharge propellant waste liquid and exhaust gas. The propellant filling system usually consists of propellant storage tanks, filling pumps, extrusion devices, pipelines and valves, control and testing equipment, etc. According to the properties of propellants, they can be divided into room temperature liquid propellants and low-temperature liquid propellants. At present, the liquid engines developed by Zhongke Aerospace use liquid oxygen and kerosene as propellants.
Shenzhou-15 crew breaks the record for single crew extravehicular activity of Chinese astronauts
On April 15th, the crew of Shenzhou-15 conducted its fourth extravehicular activity. With the close cooperation of ground staff and astronaut Deng Qingming inside the spacecraft, the two extravehicular astronauts Fei Junlong and Zhang Lu successfully completed all the scheduled tasks and safely returned to the Wentian experimental module.
As of April 15th, the crew of Shenzhou-15 astronauts has completed four extravehicular activities, setting a new record for individual extravehicular activities of Chinese astronauts. During the four extravehicular activities, three astronauts from the Shenzhou-15 crew worked closely together inside and outside the cabin, successfully completing tasks such as installing the extravehicular expansion pump group, connecting the cross cabin cables, and installing the support rods of the extravehicular load exposure platform, laying the foundation for subsequent large-scale extravehicular surgery and technology experiments.
