The crack found in the hull of the Russian upper stage “Fregat”, which is set to launch from Kourou in French Guiana. It needs to launch British satellites system OneWeb. The start is scheduled for 20 February, but due to the defect may be postponed, reports on Wednesday, January 30, RIA Novosti with reference to sources in the industry.
We are talking about the tear seam of the pipeline supply of helium in the fuel tanks. Gas is used to displace fuel in the engines. It is noted that cleft could occur during transportation.
According to one source, to make a crack on the place, just drain the fuel. But there is a possibility that the “Frigate” will have to take back to Russia. In this regard, the launch can be postponed until the end of the year.
TASS adds that the rest of the week, the staff of NPO Lavochkin, which is engaged in the production of boosters, check out “Frigate” and will determine the necessary work.
Start of the carrier rocket “Union” with British satellite project high-speed global Internet, OneWeb was announced in mid-January.
