The innovative cold propulsion system equipped on Tiandu-2 played a critical role by providing high-precision orbital attitude control during its mission in lunar orbit. This system is especially notable as it represents the first operational deployment of the liquid ammonia cold air micro-propulsion system designed for deep-space exploration tasks.
The design and implementation of the storage tank as a key component of the satellite's propulsion system were paramount. It required high precision in its formation to ensure no leaks and durability to withstand the rigors of space. Its successful application is credited to the advanced 3D printing technology that allowed the CASC development team to intricately connect internal components, significantly cutting down the development cycle and associated costs.
Moreover, the implications of this technological feat extend beyond immediate mission successes. The use of 3D printing in satellite construction presents a transformative approach for manufacturing in space, where the ability to produce complex components on demand could revolutionize future missions and space habitation.
The launch of Tiandu-2, along with Tiandu-1 and the new relay satellite Queqiao-2 on March 20, represents a comprehensive expansion of China's capabilities in space communication and navigation technology. These satellites play a crucial role in China's broader strategy to enhance its infrastructure in space, ensuring robust communication links and precise navigation support for various missions.
As the aerospace community continues to observe the performance of these newly deployed technologies, the success of the 3D-printed storage tank offers promising prospects for future applications in space exploration and satellite technology.
