Originally, Shenzhou 13 spacecraft has been on standby

Recently, Jing muchun, commander in chief of the long march 2F launch vehicle of the first Academy of Aerospace Science and technology group, and Shao Limin, deputy technical manager of Shenzhou 12 manned spacecraft of the Fifth Academy of Aerospace Science and technology group, respectively said in an interview with the media that while the launch of the long March 2F 12 rocket, the long march 2F 13 rocket also completed its preparations and entered the state of emergency rescue duty. Before the launch of the Shenzhou 12 manned spacecraft, the Shenzhou 13 manned spacecraft was ready for launch, with the capability of rapid launch and emergency rescue.

In this regard, a microblog netizen said that the rocket and manned spacecraft can make dumplings?

According to the global times, both the chang-2f carrier rocket and the Shenzhou manned spacecraft adopted the "rolling standby" strategy during the shenzhou-12 manned spacecraft launch mission. That is to say, during the shenzhou-12 manned spacecraft launch mission, both the shenzhou-13 manned spacecraft and the chang-2f-13 rocket were on standby at the launch site. If emergency rescue is needed, Both "arrow" and "ship" have the ability to launch as fast as 8.5 days to realize space rescue.

Earlier, Zheng Wei, product assurance manager of shenzhou-12 manned spacecraft project of casc-5, said in an interview that the Shenzhou spacecraft will be put into production in batches in this research and development mission, and the two ships will leave the factory at the same time. At the same time, the general assembly and testing of shenzhou-12 and shenzhou-13 will be completed at the launch site.

Shenzhou No.12 spacecraft is docking with the rocket as the launch ship. When the launch tower is ready for launch, Shenzhou No.13 spacecraft is the ground standby rescue spacecraft for this mission. It completes the preparation before propellant filling, and is in place in the plant. It can start the follow-up launch procedure at any time. Once rescue is needed in orbit, the rescue procedure can be started at any time with the cooperation of Long March 2F carrier rocket, and the astronauts can be launched into orbit in a short time to return to the ground.

In the orbital construction and operation stage of the space station, the chang-2f rocket will also adopt the "rolling backup" launch mode of "one launch and one backup". Taking this mission as an example, two rockets came into the field at the same time, first to carry out the general assembly test of yao-13 rocket, and then to carry out the general assembly test and launch of yao-12 rocket used to launch shenzhou-12 manned spacecraft. There is a cross in the process of the two rockets, and the model teams work in parallel.

In case of an accident, after receiving the emergency rescue order, the basic stage, fairing (half cover) and escape tower of chang-2f rocket can work simultaneously and efficiently.

According to the specific requirements of the space station's emergency rescue mission, the chang-2f rocket has the ability to launch in 8.5 days and 16 days, and the ability to launch in two states, which can quickly launch the spacecraft and safely take back the astronauts.

Of course, the most normal situation is that everything is going well in the space station. The rockets on duty have been quietly waiting in the technical position until they turn to the normal launch process of the next mission. This cycle may be as long as half a year.

So, will long-term vertical storage have adverse effects on the rocket? According to Chang Wuquan, the chief designer of the 2F rocket, the first president of the aerospace science and technology group, the model team, after a lot of analysis and tests, believes that they can fully withstand these changes and will not be affected.
