The RD-193 is a high performance single-combustion chamber rocket engine, developed in Russia from 2011 to 2013. It is derived from the RD-170 originally used in the Energia launcher.

The RD-193 is fueled by a kerosene / LOX mixture and uses an oxygen-rich staged combustion cycle. RD-193 was proposed as a replacement for the NK-33, which is being used in the Soyuz-2-1v vehicle.[1]

Design[]

The engine is a simplified version of the RD-191, omitting the swing assembly chamber and its related structural elements, thus reducing size and weight (300 kg) and lowering cost.[3]
