Method and Functional Diagram for Regulating the Ratio of Fuel Components and the Mass Fuel Consumption Through the Engine of the Space Tug

Topic of the graduation thesis is “Method and Functional Diagram for Regulating the Ratio of Fuel Components and the Mass Fuel Consumption Through the Engine of the Space Tug”. The master's dissertation includes 14 pictures, 5 tables and 31 literature resources. The overall workload is 58 pages. The objects of investigation are the channels for regulating the ratio of the fuel components and the mass fuel consumption through the engine of the space tug. The scientific task of the research is the development of a system for regulating the ratio of fuel components and mass consumption, which would allow to reduce the mass of guaranteed fuel reserves to 0.8% of the mass flow of fuel through the engine. The purpose of the work is to reduce the guaranteed fuel reserves and as a consequence increase the mass of the payload carried by the space tug to a given orbit. In the course of the work the method, functional diagram and analytical dependencies of the fuel ratio control channel and the mass flow rate were developed. The destabilizing factors were revealed and the degree of their influence on the regulation error was studied. The embodiment of electronic devices that regulate the ratio of components and the mass fuel consumption was presented.
