The launch mission of the Chang 11 rocket at sea was a complete success. The launch mission of Chang-11 rocket at sea was a complete success. 1

The Chang-11 rocket was developed by China Academy of Launch Vehicle Technology, affiliated to China Aerospace Science and Technology Corporation. It is a new generation of solid launch vehicles in China and the only solid launch vehicle commonly launched by land and sea in China. At present, among the land-based solid launch vehicles in the world, the Chang 11 rocket has the shortest launch preparation period. Dong Xiaobin, the chief designer of Rocket 11, said that the shorter the launch cycle, the stronger the rapid response ability, and the ability to undertake the heavy responsibility of launching emergency satellites quickly and flexibly.

This launch mission realizes the integration of rocket assembly, test, departure and launch for the first time. The Chang-11 rocket is transported to the port immediately after the final assembly and measurement, and can be transported to the launch ship within one day. The whole mission takes only three to four days. Compared with before, the mission cycle is shortened by one third, which reduces the transportation cost and possible risks during transportation, and lays a solid foundation for subsequent high-frequency and batch launches at sea.

He Xuan, the designer of the 11th Rocket Offshore Launch Support System, said that compared with the traditional land launch, the offshore launch needs to meet the positioning and orientation of rocket launch under dynamic conditions, improve the support of land-based measurement and control, test and launch, and overcome the special natural environment influences such as salt fog and mold. Through numerous simulation calculations and ground verification, the team has broken through technologies such as autonomous aiming of high-precision navigation benchmark and vertical load dynamic balance caused by flexible traction to ensure the success of launch.

sharp arrows are rising in the sea, and you are full of lofty sentiments. Compared with the previous two sea launch missions, this sea launch has realized the preparation for launching, such as localized general assembly survey and satellite-rocket docking, which greatly shortens the mission cycle, simplifies the operation process, and reduces the transportation cost and the risk of equipment impact during transportation. The superiority of Haiyang Oriental Space Port is becoming more and more prominent.

"Previously, after the rocket was manufactured, it was relatively complicated to assemble the whole rocket for testing and then transport it to the launch site by railway. Today, the industrial base of solid launch vehicle is only 5 kilometers away from the dock. After the rockets are docked, tested and loaded here, they can be launched after being transferred to the ship and trained by the whole system. The whole process only takes 3-4 days. " He Xuan, the overall designer of the rocket launch support system, introduced.

At present, the Chang-11 rocket has an annual output of 1 rounds, and it can also realize satellite launch services such as "space shuttle bus", "space shuttle bus" and "space hitchhiking" according to the characteristics of commercial space launch. In 222, the Chang-11 rocket will be launched intensively, and five to eight launch missions will be arranged throughout the year, including one to three launches at sea, which is expected to create a new record for the annual launch quantity of this type. The launch mission of the Chang 11 rocket at sea was a complete success. 2

A new breakthrough in "launching voyage"!

Chang-11 rocket is a new generation of solid launch vehicle developed by Rocket Academy, and it is also the only solid launch vehicle launched by land and sea in China. It is famous for its "quick sound and sharp arrow", which has the characteristics of "quickness, convenience and flexibility", mature technology, rapid preparation and operation, and is the forerunner of China's high-efficiency development in the commercial aerospace field.

This time, the Chang-11 rocket made a number of technical improvements, such as replacing the new servo mechanism at the first level, which improved the test coverage and maintainability of the rocket and made the launching operation simpler. The range of this launch ship is about 5km, which further expands the maneuvering range of sea launch and improves the mission adaptability.

the new mode of "integration"!

the Chang-11 rocket carrying out this launch mission is the first rocket model in China to realize the integration of rocket assembly, test, departure and launch.

after the final assembly and general measurement of the rocket is completed in the solid launch vehicle industrial base, the rocket is immediately transferred to the port, and can be transferred to the launch ship within one day, then the whole system is trained, and then the rocket can be launched after sailing to the scheduled launch sea area, which takes about three to four days. Compared with before, the mission cycle is shortened by one third, and the transportation cost and possible risks during transportation are also reduced, which lays a solid foundation for subsequent high-frequency and batch launches at sea.

The new concept of "commercial launch"!

with the continuous improvement of model technology maturity, the annual launch capacity of Chang 11 rocket has been continuously improved. At present, it has the production capacity of 1 rounds per year, and the performance launch capacity is steadily improving. According to the characteristics of the space launch market, the Rocket Academy has set up a professional model management team, which has realized the "full process, full elements, full cycle and full life" management of the model, and ensured that it can be close to the market quickly and efficiently and serve users.

In the field of commercial launch, Chang11th Rocket creatively launched three launch service modes, namely, special space car, shuttle bus and free ride in space, creating the market image of Chang11th Rocket as "good service, high reliability and quick fulfillment" in the fierce competition in the commercial space launch market, and constantly enhancing the market competitiveness.

The special space vehicle can provide customized launch service for a single user. Space shuttle bus highlights the regular launch, providing users such as commercial satellites with the opportunity to carry it regularly. On the premise of providing customized launch service for the main satellite and remaining carrying capacity, the space shuttle can carry other satellite loads that meet the requirements of orbit and weight, so as to achieve economical and efficient multi-task.

in 222, the Chang-11 rocket has started intensive launch, and 5-8 launch missions have been arranged in total throughout the year, including 1-3 launches at sea, which will set a new record for the annual launch quantity! The launch mission of the Chang-11 rocket at sea was a complete success 3
