Au KBKhA on met en cause les matières premières fournies.

Ce n'est pas impossible. Mais il va falloir qu'ils fassent un contrôle qualité à l'entrée plus rigoureux alors...

on KBKhA inspection is completed

Lyrics: Vladimir Dan'shin
Photo: Vladimir Today at 16:58 December 30 at the Voronezh factory KBKhA must complete the verification commission from Moscow, which experts are studying the reasons for the fall of the Russian satellite "Meridian." According to preliminary information, in the fall of the rocket engine may be to blame, produced at the Voronezh factory KBKhA. This was on the federal TV channels, said the head of Russian Federal Space Agency Vladimir Popovkin in a meeting with Deputy Prime Minister Dmitry Rogozin. He said: This incident has once again confirmed that the industry is in crisis. And the sickest link has engine area. Dmitry Rogozin, Vladimir Popovkin commissioned in time to January 25, 2012 to develop a specific timetable for withdrawal from the industry crisis. And the main problem to be solved - HR. However, the workers KBKhA interviewed by the correspondent of "Time of Voronezh," believe in the fall of the rocket may be to blame rather than the "human factor" and the engine KBKhA how low quality materials (in particular - metal products), of which he collected. According to the above sources, KBKhA an increasing number of low-quality materials. For example, the plants produced hardware may not be of higher quality, and third grade. This is not marriage, but to use such products in the future can only hope for a "Russian maybe." But it is not always. According to press secretary Alexander KBKhA Kazhikina, starting December 23 was the eighth in a row for this type of Voronezh engine and the fifth this year. - As a result of a failed start-up a special commission, her efforts are directed to consider all the factors that led to the emergency and to establish the root cause, - said Alexander Kazhikin. Falling "Meridian" was the fifth crash in Russian spacecraft later this year. In the third stage rocket, due to which there was a recent crash, was established designed at the beginning of this century in the Voronezh KBKhA engine RD-0124.

Ce qu'on sait maintenant de ce qui est arrivé: une chute brutale de la presion dans les tubulures alimentant le moteur RD-0124 (niveau 0 en moins de 0,6 seconde) et suivie par une probable explosion.

By January 2012, the analysis established that unlike the August 2011 crash of the Progress mission, the pressure in the fuel line leading to the engine fell really quickly: first collapsing to 10 percent of nominal amount in just 0.5 second and then reaching an absolute zero in just 0.1 second.
