Abstract
The results of the development and studies of the thrust-vector control system for a liquid rocket engine to control a space stage of the launch vehicle of the Cyclone-4M-type in case of mass asymmetry are reported. The paper discusses new structural and general-arrangement diagrams of bifunctional systems of the thrust-vector control, based on combined use of the mechanic (swinging the gimballed engine ) and gas dynamic (asymmetrical injection into the supersonic section of nozzle of the pressurization gas used by the turbine) thrust-vector control systems. Physical fundamentals for creating controlled efforts, special features of algorithms of the thrust-vector control and the stage motion control are examined. It is shown that applications of bifunctional systems of the thrust-vector control allow for significant extending the range of the thrust-vector control on retention of a high dynamic quality of the stage flight control and its power-mass and overall dimensional characteristics.
