RD-0124
Description

Engines of KBKhA development. Champion among all oxygen-kerosene rocket engines in the world in terms of specific impulse. (efficiency), providing the greatest possible energy characteristics of LV’s stage at such propellants.
Engine has highly effective systems of propellant mixture in combustion chamber, cooling of combustion chamber, the stability of the start up parameters.

Two successful test flights of “Angara 1.2 PP” LV of light class and “Angara-5” LV of heavy class with RD-0124А engine took place in 2014.
