Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com, 21 October, on May 13 this year, the fourth private commercial carrier rocket launched by hyperbola 1 was blasted off from China's Jiuquan Satellite launch Center, resulting in abnormal flight and failure of the launch mission.

According to the official knowledge of Interstellar Glory, on October 18, Star Glory organized a review meeting on the flight failure of the hyperbolic No. 1 remote four carrier rocket, and the experts at the meeting unanimously recognized the causes of the flight failure and the effectiveness of the zeroing measures. complete the zeroing closed loop.

The flight fault of the hyperbolic No. 1 remote four carrier rocket was located in the redundancy, which led to the fuel leakage caused by the lax closure of the main valve of the fuel road of the 2000N attitude control engine on the arrow, the attitude and orbit control power system lost control ability after the fuel was exhausted ahead of schedule, and the attitude of the three-stage flight segment was too bad. trigger the active security control conditions on the arrow, the rocket carries out the self-destruction command, and the flight fails.

Interstellar Glory said that the surplus problem led to the failure of the rocket flight test, which cost it dearly. At present, on the basis of the full implementation of fault improvement measures, the company is carrying out follow-up rocket development and production to ensure the success of the follow-up mission.

CTOnews.com learned that the official website of Interstellar Glory shows that the hyperbolic-1 carrier rocket is a four-stage small solid carrier rocket, all of which are solid motors, supplemented by liquid attitude control engines; the rocket has a diameter of 1.4m, a total length of 24m, a total mass of about 42 tons, a take-off thrust of 770KNX, a 500km sun synchronous orbit with a carrying capacity of more than 300kg and a 700km sun synchronous orbit carrying capacity of 225kg.

The first rocket of hyperbolic No. 1 was launched on July 25, 2019 and was successfully put into orbit. It is the first time that China's private aerospace has been successfully put into orbit.

The second rocket of hyperbolic No. 1 was launched on February 1, 2021. It malfunctioned during the flight and the launch mission failed.

The third rocket of hyperbolic No. 1 was launched on August 3, 2021, and the satellite did not enter orbit normally after separation, because the fairing was not separated normally.
