Identify hidden defects in the engines for carrier rockets «proton-M», most likely, will be possible without disassembly using a unique method of neutron activation, said in an interview with RIA Novosti, Dmitry Panov, General Director of NPO «Tekhnomash», a leading enterprise of state Corporation «Roscosmos» Federal space programme in the area of new technologies.

Earlier it was reported that all launches of «Proton» from-for the revealed problems with the engines produced «the Voronezh mechanical factory» (VMZ) were collapsed exactly a year 8 Jun 2017 year was the first post-break start. VSW was withdrawn 71 engine.

«Our experts took an active part in the work of the Commission to identify the causes of the admitted defects, and development of measures on their elimination and prevention. One of the directions the search for possible methods for determining the presence of the wrong brand of solder. Together with Lomonosov Moscow state University, Institute of physical-technical problems of the state Corporation «Rosatom», the joint Institute for nuclear research we have carried out work with samples and models for testing the seven methods of control. The prospect of solving the problem shown in the experiment of the joint Institute for nuclear research — the technique of neutron activation. Today work is already completed, will soon be given a definite answer, and, most likely, it will be possible to determine the presence of possible defects without disassembly of the engines,» concluded gentry.

Launches of «Proton» was suspended on 9 June 2016, when the orbit of the satellite Intelsat-31 suddenly appeared abnormal operation of the second stage of «Proton» — its the engine shut down prematurely. Due to the operational change programme of the third stage and the upper stage «breeze-M» spacecraft put into orbit still managed. Later the Commission of experts of «Rosatom» came to the conclusion on the separate defects in the Assembly of the engines on the «Voronezh mechanical factory» (VMZ).

Then the General Director of NPO «Energomash» Igor Arbuzov said in an interview with RIA Novosti that all of the defective engines RD-0210/0211 and RD-0213/0214 in number of 71 units for the second and third stages of the carrier rockets «proton» was returned back to VMZ. According to the conclusions of specialists of Roskosmos, when soldering components on the enterprise had used solder, not complying with technical documentation.
