Fuel tanks

Lavochkin Association, JSC currently develops and manufactures a number of propellant tanks for SC propulsion systems

    • propellant tank cavity can be manufactured with a volume from 40 to 191±2 liters;
    • amidol or nitrogen tetraoxide and asymmetric dimethylhydrazine are used as fuel cells;
    • operating pressure in the fuel cavity at the beginning of operation can be in the range from 6 to 36.3 kgf/cm 2 , depending on the volume of the fuel cavity and fuel cells;
    • aluminum and titanium alloys are used for tank body manufacturing;
    •  overall dimensions can be in the range from 456х456х534 to 830х830х780 mm;
    • mass of manufactured tanks is from 7,2 to 21,4 kg;
    • estimated time of delivery after contract conclusion is 6 months;
    • active lifetime cycle is from 1 year to 10 years;
    • mechanical loads level corresponds to the loads during SC injection by small-lift and medium-lift LV;
    •  inner diameter of fuel tanks is in the range from Ø440 to Ø720;
    • fixing method of fuel tanks is with the use of brackets, which are part of the tank and flange fixation.
