Tianbing Technology has made a breakthrough in rocket technology with the successful first flight of the Tianlong-2 liquid carrier rocket. The rocket used the liquid oxygen kerosene engine TH-11V, which was independently developed by Tianbing Technology. This engine is the world's first closed-cycle supplementary combustion engine that uses 3D printing technology.

During the 285-second flight, the TH-11V engine performed perfectly. This engine design offers several advantages over traditional manufacturing processes. Using 3D printing technology, the number of engine units is reduced by 80%, the manufacturing cycle is shortened by 70% to 80%, and the cost and weight are reduced by 40% to 50%.

In addition, the TH-11V engine has a thrust-to-mass ratio of more than 100, which means it has a high level of power compared to its weight. This feature is particularly important for rockets as it allows for a greater payload capacity and more efficient launches.

The successful flight of the Tianlong-2 liquid carrier rocket and the performance of the TH-11V engine mark a significant milestone in rocket technology. This breakthrough has the potential to revolutionize the way rockets are manufactured and designed, making them more efficient and cost-effective. It also opens up new possibilities for space exploration and commercial space ventures.
