The RD-193 is a high performance single-combustion chamber rocket engine, developed in Russia. 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.[2]
Design
The engine is a simplified version of the RD-191. Characterized by the absence of swing assembly chamber and related to other structural elements, thus reducing the size and weight (300 kg) and lower its cost.[3]
