China’s Tiandu-2 satellite has successfully utilized a 3D-printed storage tank in orbit, marking a significant milestone in the nation’s aerospace technology. According to the China Aerospace Science and Technology Corporation (CASC), this achievement represents the first in-orbit application of a 3D-printed storage tank in China.
The Tiandu-2, a communication and navigation technology test satellite, relies on a cold propulsion system that recently provided high-precision orbital attitude control during its lunar orbit. This event signifies China’s inaugural use of a liquid ammonia cold gas micro-propulsion system in deep-space exploration, enhancing the precision and efficiency of satellite maneuvering.
The storage tank, a critical component of satellite propulsion systems, demands exceptional precision, leak-proof integrity, and robust anti-fatigue properties to withstand repeated fuel filling and discharge cycles. By mastering key 3D printing technologies, the development team at CASC successfully connected components within the storage tank, significantly shortening the development cycle and effectively reducing costs.
The innovative approach to manufacturing not only accelerates production but also opens new avenues for complex component integration in aerospace engineering. The success of the Tiandu-2’s propulsion system demonstrates China’s growing capabilities in cutting-edge space technology and its commitment to advancing deep-space exploration.
On March 20, China launched the Queqiao-2 relay satellite along with the Tiandu-1 and Tiandu-2 communication and navigation technology test satellites. These launches underscore China’s expanding presence in space and its dedication to developing advanced technological solutions for communication, navigation, and exploration missions.
