[Changguang Satellite and Dongfang Space officially signed a contract for the “High Score 05” batch-production satellite launch service project, which will be launched into orbit on the first rocket of “Gravity-1” this year! 】

On April 17th 2023, Chang Guang Satellite Technology Co., Ltd. (hereinafter referred to as “Chang Guang Satellite”) and Dongfang Space held a signing ceremony for the “Jilin-1” high-resolution 05 satellite launch service project in Beijing.

Dongfang Space will use the “Gravity-1” carrier rocket to launch the “Jilin-1” high-resolution 05 satellite, providing batch and rapid network launch services for the new generation of high-resolution remote sensing constellations of Chang Guang Satellite.

At the signing ceremony, Xu Kai, deputy general manager of Changguang Satellite, expressed his expectation that the launch vehicle, satellite, data application and other industries will form a joint force to jointly promote the development of China’s commercial spaceflight. At the same time, we highly affirm the efforts made by Dongfang Space in the joint development of the star and rocket, and wish the first flight of “Gravity One” a complete success this year. Yao Song of Dongfang Space said that Changguang Satellite is the pioneer and leader of China’s commercial aerospace, and will continue to learn from Changguang Satellite, and the two sides will make progress and develop together. Dongfang Space Bu Xiangwei said that the “Jilin-1” satellite launch mission has posed new challenges to the company, and has also created a large application of large rockets. The company is confident in successfully completing the mission.

The “Jilin-1” constellation is the core project under construction of Changguang Satellite. It has built the world’s largest sub-meter commercial remote sensing satellite constellation, occupies a dominant position in remote sensing information services, and has gradually become an important source of space remote sensing information in the world. “Jilin No. 1” high-scoring 05-batch production star is the fourth-generation technology satellite of Chang Guang Satellite. It adopts a new generation of high-integration electronic control system, advanced technologies such as ultra-high-speed data transmission and electric propulsion, and adopts mass production and mass launch. , batch networking and the business model of rapidly providing remote sensing information services. It will provide higher-quality remote sensing information and product services in various fields such as homeland security, geographic surveying and mapping, land planning, agricultural and forestry production, ecological environmental protection, and smart cities, and provide customers with more abundant remote sensing data products.

“Gravity-1” is the first medium-sized solid launch vehicle for my country’s commercial spaceflight. The LEO carrying capacity reaches 6.5 tons, which triples the existing domestic solid capacity and meets the needs of low-orbit constellations and rapid launch services for medium and large satellites. The “Jilin-1” high-scoring 05-batch satellite launch mission is the first time that the “Gravity-1” rocket has been fully customized to support the construction of large-scale constellations. Through the joint design of the two parties for nearly half a year, the advantages of the large capacity and large space of the “Gravity-1” rocket will be “full and fully utilized”, which will help the construction of the “Jilin-1” constellation to greatly improve efficiency and reduce launch costs.

[“Gravity No. 1” has completed a number of static tests such as the inclined nose cone of the booster]

On the week of 30^th July 2023….  The static test is also called the static strength test. By simulating the actual force and boundary conditions of the structure in actual work, the axial Force, bending moment and shear force are used to assess the structural strength, and the accuracy of the simulation results is verified to ensure the safety and reliability of the actual work. “Gravity One” adopts many low-cost and new forms that are conducive to mass production. During the development process, a large number of finite element simulations and serial static tests were carried out, which effectively verified the design results.

Since the beginning of this year, “Gravity-1” has successively completed a series of static tests including the combination of the instrument cabin, the second-level tail section of the core, the inclined nose cone, the first-level tail section of the core, and the booster tail section. Reliability of working under complex load conditions during flight. In order to speed up the progress, many trials are designed and carried out by the company itself.

In addition, the test adopted a method of multi-channel and multi-site parallel implementation. After full investigation, domestic units that meet the test capabilities were selected to ensure that multiple static tests were completed quickly within a short period of time.
In the design of working conditions, through finite element simulation, the test team simplified more than ten working conditions into 3 to 5 working conditions (slightly different at each level), taking into account both efficiency and cost. The test adopts a staged loading method, and various working conditions are fully assessed, and the remaining strength coefficients of each section meet the service requirements.

Take the booster bevel cone as an example. Gravitation No. 1 adopts the design of uploading force, and the use of the inclined cone scheme can not only reduce the height of the section, but also provide a streamlined aerodynamic shape, but it requires high design and manufacturing capabilities. Yang Shuang, the person in charge of the oblique head cone, said that the structure is the most difficult project since the work: the oblique head cone is a special-shaped structure with a height of 4 meters. Constrained by small space and difficult force transmission and diffusion, it faces many difficulties such as bearing a concentrated load of 200 tons within a diameter of 250mm. In order to deliver on schedule, in less than half a year, the team fully practiced the concept of carrying out design and production to the end, and solved many technical problems after comparing multiple plans. In terms of testing, the team proposed an integrated loading scheme that simulated the flight state, which resolved related restrictions such as the site and loading conditions, and finally completed the delivery task on time.

At the same time as the series of static tests were completed, more than 20 flight rocket structures of “Gravity One” were produced and delivered simultaneously. This model also helps the company organize and carry out more innovative work in the future, and has accumulated valuable practical experience in “design-trial-manufacture-test-mass production”. The work of “Gravity One” is progressing smoothly as planned to ensure the complete success of the first flight in the fourth quarter. First flight test article | “Gravity One” completed….

.On the 2^nd August 2023 Dongfang Space’s first carrier rocket “Gravity-1” will make its maiden flight at Dongfang Aerospace Port in December 2023. In order to ensure the success of the first flight, Dongfang Space has carried out various research and development work in a rigorous and meticulous manner. The structural system has recently completed the vibration test of the first-level core section and achieved complete success.
