As a result of the accident, “Proton” at Baikonur had been destroyed three GLONASS satellites
accident rocket “Proton-M” was due to abnormal functioning of the angular rate sensors, deputy head of the Russian Federal Space Agency Alexander Lopatin.
July 2 from the Baikonur “cosmodrome” was launched rocket “Proton-M”, but almost immediately after starting it off course, caught fire and then fell to 2.5 kilometers from the launch site.
The result has been lost three GLONASS satellites.
According to Lopatin, the commission investigating the accident found that it was due to improperly installed angular rate sensors.
Improper installation
He said that in the case of three such missiles mounted sensor – on the one hand in the plane yaw sensors have been installed correctly, and the other (in the plane of the pitch) – is wrong.
Lopatin believes that sensor technology that is difficult to install properly secured with the use of force, after it failed to install it according to the instructions.
Booster gathered at the State Research and Production Space Center Khrunichev.
According to Lopatin, the names of experts to install the detectors are known. But talk about the extent of their guilt, he did not.
Management System “Proton-M” has developed a “Research and Production Center of Automatics and Instrument Academician Pilyugina”.
anonymous expert in an interview with RIA Novosti said that we should not put the blame for what happened on alone improperly installed sensors.
“There remain serious questions that suggest that the accident resulted in a number of problems. So it is not clear why the” Proton “kicked off by 0.4 seconds earlier. Is rocket engine start sequence diagram, it is tied to the time.’s either human error in the preparation of sequence diagrams, or a failure in the device that implements this sequence diagram. Another problem that has not been answered – if there were failures in the propulsion system or not, “- he said.
Flying with flip
Earlier, a source close to the investigation said that the control system of the launch vehicle immediately after the start began to get bad data from their sensors, resulting in a stable orientation of the rocket lost.
The video launch is seen as the “Proton” in the first few seconds of flight began to sway from side to side, then a coup and broke apart in the air.
rocket debris fell to the ground in the territory of the cosmodrome.
According to the source, faulty sensors continue to transmit information during the flight, which only made the situation worse.
What to do?
Exactly one year ago
CEO of the Khrunichev Center Vladimir Nesterov was relieved of his post.
He submitted his resignation after Press failed launch into space two telecommunications satellites with a Russian carrier rocket ” Proton-M “.
a result of problems in the upper stage “Breeze-M”, which is structurally a part of rockets, satellites failed to orbit.
At the same time, Russian Prime Minister Dmitry Medvedev suggested not simply dismiss the guilty officials, but in fact introduce a “financial liability of legal persons for poor quality products and related work”.
Experts then raised doubts that such liability will be an effective measure.
