| description | The subject of research in the article is the process of accelerating the working fluid in an electric heating thruster, which is part of the onboard propulsion system used in space tug. The goal is to obtain the characteristics of starting an electric heating thruster, which is part of an onboard propulsion system used in space tug, as a function of time, to further evaluate the preparation time of an onboard propulsion system for operation and approximating its temporal characteristics to chemical rocket engines. Tasks: the formation of the pneumohydraulic diagram of the onboard propulsion system, the structure of the onboard propulsion system, the creation of a mathematical model of the electric heating thruster, the determination of the functioning area of the electric heating thruster, which is part of the onboard propulsion system and the launch characteristics. The method used is: simulation of processes occurring at start-up in an electric heating thruster, which is part of an onboard propulsion system used in space tug. The following results were obtained: the range of limitations of the static dependence of the thrust of the electric heating thruster, which is part of the onboard propulsion system, on the flow rate of the working fluid in the heater power range was determined; dependences on the thrust time of the electric heating thruster, the flow rate of the working fluid of the electric heating thruster, and the power consumed by the electric heating thruster during the start-up process are obtained; as a result of the optimization of the coefficients of the controller of the electric heating thruster, the transfer function was obtained. The scientific novelty of the results consists in assessing the dynamic properties of an electric heating thruster, which is part of an onboard propulsion system mounted on a space tug, obtained in the field of limiting the thrust of an electric heating thruster, the flow rate of the working fluid of an electric heating thruster, the power of an electric heater of an engine, and the transfer function of a regulator of an electric heating thruster, which is part of onboard propulsion system. |
