Roskosmos specialists found seven more faulty valves in the blocks of the first stages of the Soyuz-2 launch vehicles, thereby preventing possible emergencies. Reported by RIA News with reference to a source in the rocket and space industry.
According to the source of the news agency, the decision to check the first stages of the Soyuz-2 missiles was made after a faulty valve was found in the Soyuz-ST rocket at the Kuru cosmodrome. After the replacement of the faulty part, all the first-stage units in storage and preparing for launch were tested, including the Soyuz-2 rocket launched the day before from the Plesetsk cosmodrome with three Gonets satellites.
Seven more defective parts were found by specialists. Reportedly, the products of one of the batches of valves for engines of the first stages of rocket turned out to be of poor quality. To date, all defective parts have been replaced.
The result of the check was not only the establishment of the batch number, shift and the foreman who allowed the marriage of parts produced in 2016 at the Samara enterprise "UEC-Kuznetsov", but also the prevention of possible emergencies due to these valves.
As the interlocutor of the agency added, in the event of an emergency in space, it would be almost impossible to establish the true cause of the accident.
