At present, the construction task of China's space station has entered an intensive period, and in the future, with the completion of the construction of The Chinese space station in orbit, the Tianzhou series cargo spacecraft will also usher in high-frequency and normalized launch demand.
According to the mission arrangement, at least two Launches of the Tianzhou Cargo Spacecraft will be carried out every year to deliver the cargo needed by the space station to the space station to ensure the stable operation of the space station. In order to make the Tianzhou spacecraft delivered and used as scheduled, the scientific research team improved the production line of the spacecraft.
Li Zhihui, deputy commander of the cargo spacecraft system of the Fifth Academy of Aerospace Science and Technology Group: Components and raw materials are ordered 3 years in advance, and 6 cargo spacecraft are purchased and ordered in the same batch. We must solidify the technical state of the entire product platform, which is equivalent to ensuring the consistency and stability of the state of each subsequent ship, and also solidify the launch site and some processes and mode mechanisms of future flight control, and (use) mass production to adapt to the high-density launch task of two cargo ships per year.
In the subsequent mission, the Tianzhou cargo spacecraft will also use a semi-sealed cargo compartment module, which can also carry some relatively large equipment for the replacement of space station products while transporting supplies.
Li Zhihui, deputy commander-in-chief of the cargo spacecraft system of the Fifth Academy of Aerospace Science and Technology Group: From Tianzhou No. 1 to Tianzhou No. 5 are all fully sealed, and the semi-seal is in this place, we open a hole in it, we can open a hole in it, we can transport large goods, for example, (the sun) sail board has a problem, you can put this sailboard into it, and assemble it through astronauts in orbit, which is relatively flexible.
In the future, the Tianzhou cargo spacecraft will also have a fully open cargo compartment, which is simply to open the entire cargo compartment so that larger satellites and large antennas can be sent to the space station.
