Liquid propellant rocket engine RD-843 of the 4th stage of the launch vehicle was worked out by the Ukrainian M.K. Yangel State Design Office Yuzhne and produced by the A.M. Makarov Southern Machine-Building Plant.
The launch vehicle placed two satellites into sun-synchronous orbits. The first one is the OPTSAT-3000 with the weight of 368 kilograms that was produced by Israel’s defense concern Israel Aerospace Industries on order of the Italian Ministry of Defense. The second is Venus with the weight of 264 kilograms for the project of the Israel Space Agency and National Center of Space Research of France.
‘This launch became the tenth within the Vega program and the second in 2017. Totally, Vega placed into orbit 25 satellites for 19 clients all over the world during five years of work’, the message said.
According to Focus, the State Design Office Yuzhne received the right to supply the rocket engines for the launch vehicle Vega within the agreement with the Italian company Avio in 2004. Yuzhne works out the liquid propellant rocket engine RD-843 that is the part of the space tug and it aims to develop the thrust, thrust vectoring in pitch and yaw rotation, evasion of the space tug and removal of the space tug from the orbit.
Yuzhne worked four years to create the unique space tug - liquid propellant rocket engine RD-843 with the thrust of 250 kilograms.
