The RD-170 is a rocket engine developed in Russia and used on the Energia launch vehicle and the Zenit family of rockets. It’s a staged combustion cycle rocket engine that burns liquid oxygen and kerosene.
The RD-170 engine operates on the principles of the staged combustion cycle, where propellants are partially burned in a pre-burner before entering the main combustion chamber. The specific values for enthalpy, velocity, and total energy at the nozzle exit would depend on the engine’s design and operating conditions. For precise values, specific data or specifications for the RD-170 engine would be required.
The total energy () at the nozzle exit can be expressed as:
where,
- E is the Total Energy, i.e sum of kinetic and potential energy
- Â is the static enthalpy at the nozzle exit,
- Â is the velocity of the exhaust gases relative to the reference frame of the exhaust gases
