Revolutionary Advances in Satellite Deployment: Tianbing Technology’s Tianlong-3 Success
Summary:
- Tianbing Technology successfully conducted the "36 satellites from one rocket" separation test, achieving a significant milestone in satellite deployment technology.
- The innovative memory alloy mechanism improved safety and reduced costs, setting a new standard in the industry.
- The Tianlong-3 rocket is poised to enhance China’s commercial aerospace capabilities and support extensive low-orbit operations.
On October 27, Tianbing Technology marked a pivotal moment in aerospace engineering with the successful completion of their innovative "36 stars in one rocket" separation test for the Tianlong-3 large liquid launch vehicle. Conducted at the company’s advanced manufacturing base in Zhangjiagang, this test represents a groundbreaking achievement as it becomes the first instance in China to deploy 36 satellites simultaneously, setting a national record for satellite separation within domestic application contexts.
Transforming Satellite Separation Technology
Traditionally, multi-satellite deployment has relied on explosive bolts and pyrotechnic devices coupled with springs, methods fraught with safety hazards, high costs, and considerable ecological implications. These traditional systems also pose challenges in pre-launch detection and optimization of space utilization. Recognizing these limitations, Tianbing Technology has pioneered research aimed at launching multiple satellites effectively with a single rocket.
The company has developed an integrated design solution that addresses these challenges through the innovative application of a memory alloy unlocking mechanism. This cutting-edge approach achieved critical actions during the separation test—preload release, unlocking, and satellite separation—demonstrating the reliability and efficiency of the new design while significantly advancing safety and testability metrics.
Enhanced Performance Metrics
The newly implemented separation technology yielded impressive results: impact strength was minimized by 90%, overall weight was reduced by 60%, and the solution ensured zero emissions and pollution. Furthermore, the costs associated with this advanced technology are merely 30% of those required by conventional systems.
The successful execution of the "one rocket, 36 satellites" separation test underscored the Tianlong-3 rocket’s mass launch capabilities and its potential for large-scale satellite delivery, solidifying Tianbing Technology’s position as a trailblazer in the domain of commercial aerospace.
Leading the Future of Commercial Aerospace
As China’s first large-scale liquid rocket designed for low-Earth orbit with a transport capacity exceeding 20 tons, the Tianlong-3 is a testament to Tianbing Technology’s commitment to innovation. Incorporating over 50 key technologies, with more than 30 being implemented for the first time, the Tianlong-3 is designed to meet global standards of reliability and cost-effectiveness.
This major breakthrough in satellite and rocket separation systems is expected to support efficient, affordable launch services, benefiting low-orbit constellation networking missions while enhancing the construction of China’s space infrastructure.
Currently, Tianbing Technology boasts a comprehensive operational framework that includes self-research, large-scale manufacturing, and specialized launch stations. Centralized in cities like Beijing, Xi’an, Gongyi, and Suzhou, the company has established an intelligent aerospace manufacturing and launch ecosystem capable of producing 30 Tianlong-3 rockets and 500 Tianhuo engines annually. Plans are already in motion for the first flight of the Tianlong-3 before the close of 2025, with ambitions to facilitate over 60 high-frequency launch missions each year.
Specifications and Capabilities
The Tianlong-3 rocket, which began model development in March 2022, boasts an impressive length of 72 meters and a takeoff weight of around 600 tons. Its first stage is powered by nine "Skyfire 12" engines functioning in parallel, allowing it to transport between 17-22 tons in low-Earth orbit and 10-17 tons in sun-synchronous orbit. These capabilities place the Tianlong-3 on par with leading international launch vehicles like SpaceX’s Falcon 9, enabling it to support the deployment of extensive satellite networks and fulfill the transportation needs of the Chinese space station.
Conclusion
The milestones achieved by Tianbing Technology signal not just advancements in rocket technology but a transformative shift in the capabilities and ecosystem of the commercial aerospace industry in China. With its record-setting satellite deployment system and the ambitious plans for the future, the Tianlong-3 rocket is set to redefine what is possible in satellite launches, contributing to a more connected and technologically advanced global landscape.
