The failure to launch the Vega rocket, which deviated from the trajectory without completing the mission, was due to an integration error during the installation of engines on the overclocking unit AVUM. This was reported by UNN with reference to the press service of the State Space Agency of Ukraine.
The statement appeared against the background of the fact that the RD-843 marching engine unit was developed in Ukraine by Pivdenne Design Bureau, which is serially manufactured at Pivdenny Machine-Building Plant under a contract with AVIO (Italy) and delivered to the customer for further installation on the fourth stage of pH Vega (overclocking unit AVUM).
“On November 17, 2020, during the next launch of the Vega launch vehicle as part of Arianspace’s VV17 mission, an emergency occurred that resulted in the loss of two satellites.
According to the official statement of Arianspace, it was previously established that the incident was caused by an integration error (“integration error”) during the installation of engines on the overclocking unit AVUM, “- said in a statement.
It is noted that this led to the fact that “the rocket lost control immediately after turning on the engine of the fourth stage of the launch vehicle.”
In connection with the incident, DKA and Pivdenmash express their support to Arianespace and its cooperation partners.
It will be recalled that the Vega rocket with two scientific satellites for remote sensing of the Earth launched from the cosmodrome in Kourou in French Guiana and deviated from the trajectory without completing the mission . Pivdenmash reacted to the failure of the Vega rocket launch.
As previously reported in UNN , in 2019, the launch of a light rocket Vega from the Kourou Cosmodrome in French Guiana with a military satellite Falcon Eye 1 of the United Arab Emirates (UAE) on board failed .
