Recently this month of June July 2023 , 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 conducted 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 in
This round of separation tests was completed in the Deep Blue Aerospace Nantong rocket assembly base, and the fairing was completely recovered after multiple tests. The main technical indicators of this round of fairing separation test have been completed:
This round of tests 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-pyrotechnic connection and unlocking mechanism, which is the first time in domestic fairing separation tests.
This round of fairing separation test is one of the phase tests before the first flight of the “Xingyun-1” liquid reusable launch vehicle. The success of this round of tests will pave the way for the first flight of the “Xingyun-1” rocket in 2024 established a solid foundation.
Why did the rocket separate the fairing? The launch vehicle will encounter harsh environments during flight. The fairing protects the satellite load from aerodynamic force 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 the rocket’s carrying capacity.

中国天眼有新发展 – 中国天眼查询nanohertz gravitational wave breakthrough ] Searching for nahertz gravitational waves is one of the focal issues in the international physics and astronomy fields. A Chinese research team recently used the “China Sky Eye” FAST to detect key evidence of the existence of nanohertz gravitational waves, which is an important breakthrough in the search for nanohertz gravitational waves. This discovery marks that my country’s nanohertz gravitational wave detection and research have simultaneously reached the world’s leading level, which is of great significance for understanding supermassive black holes, the history of galaxy mergers, and the formation of large-scale structures in the universe.
中国天眼Discovery of key evidence for the existence of nanohertz gravitational wave “China Sky Eye” (FAST) ushered in a major breakthrough again. Using FAST observation data, the Chinese Pulsar Timing Array (CPTA) research team found key evidence of the existence of nanohertz gravitational waves, indicating that my country’s research on nanohertz gravitational waves has reached the leading level in synchronization with the world. Relevant research results were published online in Astronomy and Astrophysics Research on June 29.
The nanohertz gravitational wave is a kind of gravitational wave with very low frequency, and the gravitational wave is caused by the disturbance of the surrounding space-time caused by the accelerating mass object. The detection of gravitational waves with a frequency as low as nanohertz will help astronomers understand the origin of the structure of the universe. It will also help physicists to detect the growth, evolution and merger process of the most massive celestial body in the universe, that is, the supermassive black hole. Gain insights into the fundamental physics of spacetime.
At present, the research on nanohertz gravitational waves has become one of the focuses of international competitions in the fields of physics and astronomy. Theory predicts that nanohertz gravitational waves are mainly produced by the merger of supermassive black holes. The North American Nahertz Gravitational-Wave Observatory, the European Pulsar Timing Array and the Australian Parkes Pulsar Timing Array have each carried out 20-year-long Nahertz gravitational-wave searches.
However, since the frequency of nanohertz gravitational waves is extremely low, the period lasts for several years, and its wavelength can reach several light-years, its detection is extremely challenging. The long-term timing observation of a group of millisecond pulsars with extremely regular rotation using a large radio telescope is the only known detection method for nanohertz gravitational waves.
In this study, the CPTA team used FAST to conduct long-term systematic monitoring of 57 millisecond pulsars, and formed these millisecond pulsars into a galaxy-scale gravitational wave detector to search for nanohertz gravitational waves. Based on independently developed software, the team conducted an in-depth analysis of the data collected by FAST with a time span of 3 years and 5 months, and found a nanohertz at a confidence level of 4.6 sigma (false positive rate is less than 1 in 500,000). Key evidence for a quadrupole-related signal characteristic of gravitational waves.
However, due to the short observation time, the researchers are still unable to determine the main physical source of the nanohertz gravitational waves.
It is worth mentioning that the European Pulsar Timing Array-India Pulsar Timing Array, the North American Nahertz Gravitational-Wave Observatory and the Australian Parkes Pulsar Timing Array and other pulsar timing array cooperation groups also announced similar the result of. “The four international teams independently obtained the key evidence for the existence of nanohertz gravitational waves, which allowed the research results to be mutually verified and further improved the accuracy of this result,” Li Kejia said.
He Zishan, chair professor of Peking University and academician of the American Academy of Arts and Sciences, believes that this major scientific breakthrough has a profound impact on the evolution of galaxies and the study of supermassive black holes, and also opens a new window for gravitational wave astrophysics…
