Abstract: The study focuses on the specific features of a multiflow ejector equipped with variable-length links to control the thrust vector. Conditions when the deflection angle of the thrust vector can vary within the range from plus 180 degrees to minus 180 degrees, in any direction within a complete geometrical sphere, are considered for the first time ever from a general point of view. Kinematic schemes with variable length links and with flexible links are considered using the CFD techniques within the framework of conceptual designing. Technical possibilities are shown for controlled distribution of the energy through differently orientated ejector channels, while maintaining constant pressure at the inlet to the nozzle assembly. Options are considered for modification of the Laval nozzle with a rotary diffuser. The research results are patented and are intended to be used in the educational process for designers' training, backed my the philosophy of science and technology, and with the reference to the Euler methodology within the framework of interdisciplinary works. The results of the performed studies are mainly used to promote scientific research and development activities in creation of energy-efficient oil and gas production technologies.
