Russia’s Energomash Scientific and Production Association will soon begin work with the RD-191 engine to boost the capacity of the Angara-A5M heavy carrier rocket, State Space Corporation Roscosmos Chief Dmitry Rogozin wrote on his Facebook page on Tuesday.
"Work will begin soon to boost the RD-191 engine to increase the capacity of the Angara A5M heavy carrier rocket," the Roscosmos chief wrote.
The RD-191 is a single-chamber engine with a vertically-arranged turbopump unit. Its development started in late 1998. This engine with the afterburning of oxidizer-rich gases is designated for the domestic Angara carrier rockets and is based on the design of RD-170/171 engines. The first firing test of the RD-191 engine was held in July 2001.
The Angara is a family of Russian light to heavy carrier rockets that was developed to replace Proton-M and Rokot launchers. As compared to them, the new family of carrier rockets uses environmentally-friendly propellant components. So far, only two launches have been carried out and both of them have been conducted from Plesetsk cosmodrome in north Russia: a light Angara-1.2PP rocket blasted off in July 2014 and a heavy Angara-A5 lifted off in December 2014.
Vostochny spaceport in the Amur Region in the Russian Far East will become the basic launch site for the Angara family of carrier rockets, TASS reports.
