The paper presents calculation results for specific pulse of liquid-propellant rocket engines (LPRE) through addition of helium in the propellant systems, i.e. N2O4 + unsym-metrical dimethylhydrazine, liquid O2 + kerosene, liquid O2 + liquid H2, liquid F2 + liquid H2. The article shows that for the first two propellant systems (N2O4 + unsymmetrical dimethylhydrazine, liquid O2 + kerosene) an addition of helium under definite conditions results in increase of the specific pulse.
