China is breaking new ground in space technology with the recent deployment of the Tiandu-2 satellite, which features the country’s first-ever in-orbit application of a 3D-printed storage tank. Developed by the China Aerospace Science and Technology Corporation, this innovative storage solution is a critical component of the satellite's cold propulsion system, demonstrating China's advancing capabilities in deep-space exploration.
The Tiandu-2’s cold propulsion system successfully provided high-precision orbital attitude control during its mission around the moon. This achievement marks the first use of a liquid ammonia cold gas micro-propulsion system in such a context, showcasing the potential for more efficient and sustainable space exploration technologies.
The 3D-printed storage tank is essential for the satellite's propulsion, requiring exceptional precision, leak-proof design, and robust anti-fatigue performance to handle repeated fuel filling and discharge cycles. By utilizing 3D printing, the development team was able to connect the components inside the storage box seamlessly, significantly shortening the development cycle and reducing costs.
This milestone follows China’s significant launch on March 20, which included the new relay satellite Queqiao-2 and two communication and navigation technology test satellites, Tiandu-1 and Tiandu-2. These advancements position China at the forefront of satellite technology innovation, with implications for future missions and global space collaboration.
