Third stage of launch vehicle “Soyuz-2-1á” to orbit space apparatuses and piloted rockets from cosmodroms of Russia and Kuru (France).
LRE RD0124A
To be used in second/third stage of "Angara" LV family to orbit a space apparatus of a heavy class from Russian Spaceports.
The RD0124A engine is developing on the basis of RD0124 (14D23) though it has several design differences in what concerns the space apparatus deviation control, pressurization of the tanks, and it also differs in increased time operation during the flight.
The engines were developed using oxygen rich closed cycle. They assured reliable operation through preburner gas low temperature. They posses the highest energy characteristics for the engines of similar class.
