1.2 OPS with two functional turbopump units
OPS with two functional turbopump units – gas hydraulic and hydraulic - providing the possibility of oil supply to hydraulic actuators during various ground checks and during LV launch and flight.
The gas hydraulic unit turbine driving is effected by high-pressure cold gas, for hydraulic unit - by fuel taken from the engine.

1.3 OPS with two functional units
OPS with two functional units – gas hydraulic and hydraulic.
Gas hydraulic - is a unit of turbopump type; for driving its turbine, high-pressure gas is used.
Hydraulic – is a unit using fuel taken from engine for feeding hydraulic actuators.
The functional units ensure feeding of hydraulic actuators during various ground checks and during LV launch and flight.
