Development Progress | Deep Blue Aerospace completed the first fairing separation test in China using a non-pyrotechnic connection unlocking mechanism…
On the 2nd September 2023….. Recently, the separation test of the fairing of the “Xingyun-1” liquid recyclable and reusable launch vehicle of Shenlan Aerospace was a complete success. This is the first test in China to use a non-pyrotechnic connection unlocking mechanism to separate the fairing. In order to fully verify the separation state of the fairing under different deviations, Deep Blue Aerospace has carried out many experiments on this round, all of which use the self-developed non-pyrotechnic connection unlocking mechanism. The separation timing of the test is correct, which is basically consistent with the simulation results. No damage occurred.
This round of separation tests was completed at the Deep Blue Aerospace Nantong Rocket Assembly Base, and the fairing was completely recovered after multiple tests.
This round of separation tests was completed at the Deep Blue Aerospace Nantong Rocket Assembly Base, and the fairing was completely recovered after multiple tests.
This round of testing used the same set of connection and unlocking mechanisms to complete multiple separation tests within three days, verifying the reusability and rapid response capabilities of the self-developed non-pyrotechnical connection and unlocking mechanism. This is the first time in domestic fairing separation tests. This round of fairing separation test is one of the phased tests before the first flight of the “Nebula-1” liquid recyclable launch vehicle. The success of this round of test will lay the foundation for the successful first flight of the “Nebula-1” rocket in 2024. Solid foundation.
Why do rockets need to separate their Fairings?
The launch vehicle will encounter harsh environments during flight. The fairing protects the satellite payload from the aerodynamic forces and aerodynamic heat and also reduces the aerodynamic resistance of the launch vehicle during flight. After leaving the atmosphere, the launch vehicle is no longer affected by aerodynamics and throwing away the fairing helps to increase rockets capacity..
