The research goal is to calculate and support methodically rig tests of the LJS with feeding from the cruise engine lines. Mathematical modelling is used during the research. The main research results are as follows. Earlier developed mathematical model of nonstationary flows through fuel lines of control units, electric and dynamic processes through electric controlled fuel valves and gas dynamic processes in combustion chambers of control units is verified and improved using experimental data of the rig tests. The results of rig firing tests of a single control unit built in the form of the two-component thruster and the rig version of the liquid jet system with 10 control units are systematized. It is shown that this calculated and methodic support for cyclograms of rig tests allows collection of added information about LJS parameters, which cannot be measured during rig tests. The possibility of applying the results of rig tests of the LJS operation in combination with the cruise engine of the third stage is supported to predict the LJS operational parameters under flight conditions.
