Tianzhou 7 arrives in Wenchang! Expected to launch in January 2024
Recently, after completing the work related to leaving the factory, the “Tianzhou 7” cargo spacecraft has arrived at the Wenchang Space Launch Site in Hainan Province, China, People’s Republic of China. Subsequent final assembly, testing and other work will be carried out as planned. Preparations for the launch site for the next cargo supply mission are underway as planned. Expand.
It is expected that in January 2024, the “Tianzhou-7” cargo spacecraft will be launched by the “Long March 7” Yao-8 carrier rocket. The spacecraft will ascend using the rapid rendezvous and docking mode and dock behind the “Tianhe” core module of the Chinese Space Station. Send a new batch of cargo supplies to the port for the “God Seventeen” mission. Before the “Tianzhou-7” spacecraft goes up, the “Tianzhou-6” spacecraft will unlock and separate from the rear port of the “Tianhe” core module, freeing up the docking port for the former.
The “Tianzhou-7” cargo spacecraft is the second in a new batch of “Tianzhou” spacecraft. This batch has developed and produced six spacecrafts, “Tianzhou-6” to “Tianzhou-11”. Compared with the “Tianzhou-5” spacecraft in the previous batch, the “Tianzhou-7” spacecraft has undergone system upgrades and greatly improved the cargo compartment. The cabin volume has increased by 20% and the transportation capacity has increased by about 500. Kilogram, the maximum transport capacity has been increased from the previous 6.9 tons to about 7.4 tons, and the materials provided to astronauts will be able to support longer missions. Based on the increase in transportation capacity, the launch density of the space station mission “Tianzhou” cargo spacecraft has been adjusted from the previous 2 times/1 year to 3 times/2 years, with an average of one launch mission every 8 months, and the subsequent launch density will be further reduced.

The “Tianzhou-7” cargo spacecraft adopts a dual-cabin tandem configuration, with a propulsion cabin and a cargo cabin from bottom to top. The total length of the spacecraft is 10.6 meters, the maximum diameter of the main body (cargo compartment) is 3.35 meters, the dry mass is 6.5 tons, the maximum upward transport capacity is 7.4 tons, and the cargo-cargo ratio reaches 0.53. The “Tianzhou” improved cargo spacecraft is the spacecraft with the strongest transportation capacity, the highest cargo load ratio, and the most comprehensive on-orbit support capabilities among the world’s active cargo spacecraft.
Since the establishment of the space station, the launch missions of China’s manned space project have entered a normalized stage, with 2 manned launch missions and 1 to 2 cargo launch missions being carried out on a regular basis every year. According to the plan, China’s manned space program will carry out four launch missions in 2024: “Tianzhou 7”, “Shenzhou 18”, “Tianzhou 8” and “Shenzhou 19”. Among them, “Tianzhou 7” “No. 1” mission will take the lead.

The reporter learned from China Aerospace Science and Technology Group Co., Ltd. on July 23 that the main engine of my country’s manned moon landing rocket was tested in the Fengzhou Test Area of the Sixth Academy of Aerospace Science and Technology Corporation, and achieved continuous success. This test run verified the engine flight mission profile, and provided strong support for the solidification of the engine technical state, the establishment of the product technical baseline, and the improvement of reliability.
The engine is the power source of the rocket, and its development process is very complicated. Test run is an important link in the engine development process, and there are dozens of types. In layman’s terms, engine test run is the process of igniting the engine and verifying the rationality of its design scheme and process reliability. This is an indispensable and important part of the development and delivery of a type 1 engine. It will run through all stages before and after engine development. Each stage of test run has different meanings, and the ignition time varies from a few seconds to hundreds of seconds.
It is reported that the engine used in this test run uses advanced liquid oxygen kerosene as fuel, which is improved and iterated from the high-thrust liquid oxygen kerosene engine used by the new generation of launch vehicles such as the Long March 5. The thrust reaches 130 tons. The R&D team of the Sixth Academy of Aerospace Science and Technology Group adheres to the concept of digital design, and has successively overcome key technical problems such as engine start-up and shutdown sequence, engine wide-range continuously variable thrust, and engine long life and high reliability.
In addition, the continuous success of the test run has fully verified the reliability of a number of new carrying process technologies. The engine production of this test run adopts the concept of intelligent manufacturing, and actively applies new materials, new processes, and new technologies. The inner wall of the thrust chamber of the core component adopts a new protective coating, key assemblies adopt automatic welding technology, and a large number of components adopt 3D printing technology.
During the preparation of the engine test run, the participants in the research and test conducted tests and verifications on each subsystem of the test through comprehensive means such as digital modelling, simulation calculation, and system debugging. The successful test run shows that the test area has greatly improved the multi-station parallel test run capability and test efficiency by optimizing the workflow.

Design Principle’s
LOW COST- Cost reduction is an important condition for improving the competitiveness of launch vehicles in the domestic and foreign satellite launch markets. The key to the development of small launch vehicles is to reduce costs. On the one hand, make full use of the basic technology of the new generation of launch vehicles to reduce the cost of development. During the design process, the idea of low-cost design should always be implemented, and the system configuration should be simplified as much as possible while ensuring reliability; launch operations should be simplified to reduce launch costs. Using kerosene/liquid oxygen engine, the light fuel cost saves millions of yuan compared with before.
High reliability is the lifeblood of a rocket. Follow the reliability design principle of “simple is reliable”, and strive for simplicity in stand-alone or system design; through strict quality assurance system and quality management system, control product design and production quality. The design reliability is 95%. After further optimization, the reliability of the first flight has been increased to 98%, which is 1% higher than that of the most secure Long March 2 F-type.
Adaptable- To meet the diverse needs of users, it can not only adapt to the launch of small satellites in various orbits, but also launch double or multiple satellites; it can adapt to new launch sites or launch at existing launch sites. During its maiden flight, the Long March-6 completed 20 satellites in one rocket, setting a new record for Chinese satellite launches.
Short cycle -The technology of the basic type of new-generation carrier rocket is fully applied, the development cycle is short, the launch method is simplified, the launch cycle is shortened, and the requirements for rapid launch are met. The launch preparation time for the first flight only takes one week
