Recently, Beijing Jiutian Xingge Aerospace Technology Co., Ltd. successfully rolled off the production line of the first type

In the future, we will develop new generation propellant tank manufacturing technologies such as composite material tank manufacturing technology, co-bottom molding technology, large-diameter tank manufacturing technology, and make due contributions to the development of my country's commercial aerospace. Recently, Beijing Jiutianxingge Aerospace Technology Co., Ltd. completed an angel round financing of tens of millions of yuan, led by Yuanhang Capital. Beijing Jiutianxingge Aerospace Technology Co., Ltd. (hereinafter referred to as Jiutianxingge) was established in August 2019. It is a senior technology/equipment designer in the field of liquid carrier rocket manufacturing in China, a senior technical expert in the field of carrier rocket structure insulation, and rocket assembly/general survey Experts and professional talents such as welding/riveting national-level skill masters are formed. The company focuses on the core component assembly of carrier rockets. The current core products and business are normal temperature/cryogenic liquid rocket propellant tanks, liquid rocket body R&D and manufacturing, and new The first generation of propellant tank and liquid rocket body assembly production line will soon form the first domestic commercial rocket propellant tank and rocket body manufacturing, assembly and testing base. The propellant storage tank is one of the key sub-systems of the liquid carrier rocket. It is the main body of the liquid carrier rocket's body structure. In addition to being a liquid container to realize the functions of propellant storage and pressurized transportation, it is also the main bearing structure of the rocket body. The rocket propellant tank occupies 80% of the volume and weight of the whole rocket body structure, and the cost accounts for about 25% of the whole rocket. Liquid rocket storage tanks are the most critical upstream supply chain product in commercial liquid rockets. It is also an area where the process is complex, the technology and engineering threshold is high, and technology and talent are scarce. The timely establishment of Jiutian Xingge Company has provided many private commercial rocket companies in my country with supporting key links in the liquid rocket industry chain. It is also expected to become a useful supplement and backup to the country's overall aerospace manufacturing capacity. At present, Jiutian Xingge has completed the technical reproduction of all box parts, and has overcome many technologies such as spinning forming of large parts, normal temperature/low temperature storage tank insulation, thin-walled weak rigid body deformation control, etc., and has mastered covering the rocket body. The machining, welding, testing and other process methods and standard specifications involved in the manufacture of parts have the ability to develop a number of core parts of the rocket body. The company's production base has received strong support from local government funds, workshops, and equipment. The production base is expected to start construction before the end of the year, and strive to become a commercial aerospace core component brand manufacturing center. After completion, it will have the ability to supply 20-30 rocket core components per year. Professor Wang Xinhe, a partner of Yuanhang Capital, believes that the rapid development of my country’s commercial rockets has put forward an urgent demand for the supporting manufacturing capabilities of rocket storage tanks. Rocket storage tank manufacturing is a typical advanced manufacturing project with high threshold and high scarcity. Commercial value of social significance. Yuanhang Capital has invested in a number of commercial aerospace star projects such as rockets, satellites, measurement and control, and satellite applications. The investment in the rocket storage tank project of Jiutianxingge Company is another vivid embodiment of Yuanhang Capital's investment philosophy of the entire industry chain. Wang Zhifeng, CEO of Jiutianxingge, said that Yuanhang Capital's investment has provided surging impetus for the company's development. Since its establishment, the company has established business contacts with a number of private commercial rocket companies, and is currently focusing on the maturity of the manufacturing process of normal temperature/low temperature reusable liquid rocket tanks, the integration of related pipelines and tank fuel delivery technologies, and strive to become commercial Rocket Company provides advanced and reliable storage tank products, forming a segment-level delivery capability. In the future, we will develop new generation propellant tank manufacturing technologies such as composite material tank manufacturing technology, co-bottom molding technology, large-diameter tank manufacturing technology, and make due contributions to the development of my country's commercial aerospace.
