The RD-0110R (Russian: Ракетный Двигатель-0110Р (Р - рулевой), romanized: Raketnyy Dvigatel-0110R, lit. 'Rocket Engine 0110R (R - rulevoy, steering)', GRAU index: 14D24) was a rocket engine burning kerosene in liquid oxygen in a gas generator combustion cycle. It had four nozzles that can gimbal up to 45 degrees in a single axis and was used as the vernier thruster on the Soyuz-2.1v first stage. It also had heat exchangers that heat oxygen and helium to pressurize the LOX and RG-1 tanks of the Soyuz-2.1v first stage, respectively. The oxygen was supplied from the same LOX tank in liquid form, while the helium was 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 optimize 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 RKTs Progress. The RD-0110R engine was produced at the Voronezh Mechanical Plant.
