Three of the carrier rocket “proton-M” will be disassembled for replacement of the engines of the second and third stages, the launches will be resumed after 3.5 months. About this on his page on Twitter said Deputy Prime Minister Dmitry Rogozin.
He also said that the Voronezh mechanical plant (VMZ), which assembles the engines for booster, support will be provided for technical re-equipment. Saturday, January 28, Rogozin visited VMZ, where a meeting was held with the participation of the General Director of Roscosmos Igor Komarov.
Wednesday, 25 January, “Kommersant” with reference to several top-managers of enterprises of the space industry reported that the leadership of the Roscosmos withdrew in VMZ all the engines of the second and third stages of the carrier rockets “proton-M”, released in the last few years. According to interlocutors of the edition, the reason for this decision was the technological problems that are discovered during testing of one of the liquid engines of the second stage of the launch vehicle.
In particular, it was found that during the Assembly of engines is materials using precious metals used “non-liquid components”, which turned out to be less heat resistant. According to the publication, the situation caught the interest of the FSB and the Investigative Committee, who are trying to understand how was the replacement of material, if the documents are all the engines in order.
Then in Roscosmos said that the Corporation carries out the total quality assurance of products manufactured by the enterprises of the sector, therefore possible delay of launches of carrier rockets “proton”.
According to test results, Roskosmos, said that the production engine of the second stage of the carrier rocket “proton-M” was used a solder that does not match the design documentation. Instead of standard they used other, more expensive solders with the content of the precious metal.
After the meeting at VSW Rogozin said that all those responsible for the substitution technology and the documentation will be “severely punished”.
