Domestic reusable commercial rocket technology welcomes new progress.

On June 9 at 16:23, the Zhuque-2 improved Long March 6 carrier rocket was launched from the Dongfeng Commercial Aerospace Innovation Test Area, successfully delivering the Qianfan DTC 01 satellite and the China Mobile 02 satellite into their planned orbit. The flight test mission was a complete success. In this mission, the Zhuque-2 completed an important technological improvement by using a new method for the separation of the first and second stages of the rocket. In the past, the separation was achieved by explosive devices similar to explosives, which had obvious shortcomings as they were disposable and could not be tested in advance. This time, the Zhuque-2 used pneumatic push rods instead of explosive devices, pushing the piston with high-pressure gas to easily separate the second stage of the rocket. Shang Mingyou, the deputy chief designer of the Zhuque-2 improved carrier rocket, said: "Firstly, we eliminated explosive devices; secondly, we can test it on the ground, adding gas at any time to check its thrust; and thirdly, it is relatively safer. This was independently developed by us, and its controllability has also been improved." In addition, Shang Mingyou told reporters that this new technology has even greater potential - to facilitate the reuse of rockets. Previously, explosive devices were disposable, but pneumatic push rods can work repeatedly. This technology is inherited from the reusable Zhuque-3 rocket, allowing for the sharing of technological expertise and the upgrading of supporting industries, improving the overall performance of rockets.
