The RD-0110R (GRAU Index 14D24) is a rocket engine burning liquid oxygen and kerosene in a gas generator combustion cycle. It has four nozzles that can gimbal up to 45 degrees in a single axis and is used a the vernier engine on the Soyuz-2-1v first stage. It also has heat exchangers that heats oxygen and He to pressurize the LOX and RG-1 tanks of the Soyuz-2.1v first stage, respectively. The Oxygen is supplied from the same LOX tank in liquid form, while the He is supplied from separate high pressure bottles (known as the T tank).
The engine's development started in 2010 and it is a heavily modified version of the RD-0110. The main areas of work were shortening the nozzles to optimized them for the atmospheric part of the flight (the RD-0110 is a vacuum optimized engine), propellant piping, heat exchangers and the gimballing system, which was developed by TsSKB Progress. The RD-0110R engines is produced on the Voronezh Mechanical Plant.
