Abstract

The subject of the research in the article is the process of preparing the working fluid for launching an engine installation with an electric heating engine. The goal is to minimize the time for preparing the working fluid for launch by developing an algorithm for thermostating and barostating of elements of a propulsion system with limited power of the power supply system. Tasks: analysis of the structure of a propulsion system with an electric heating engine, selection of an installation control controller, the formation of an algorithm for preparing the working fluid for the first launch, the study of the reserve time for preparing the working fluid for launch with limited power supply system, the formation of an algorithm for minimizing the starting time. The methods used are: circuit analysis, energy balance and algorithmic analysis. The following results were obtained: the structural diagram of the propulsion system was analyzed, a control unit based on the Arduino Leonardo controller was selected, the first start-up algorithm was compiled, which consisted of the barostatting of the tank, thermostatting of the steam generator, barostatting of the receiver, and thermostatting of the electric heating engine; A start-up cyclogram with reduced time was constructed, an algorithm with a minimum start-up time of the propulsion system was formed. The scientific novelty of the results is as follows: the procedures included in the algorithm for preparing the working fluid for the first launch of the propulsion system are formed, a cyclogram for preparing the working fluid for the first launch is constructed, a cyclogram for reducing the time for preparing the working fluid for the first launch of the installation is constructed based on the energy balance of power consumption with limitation power plant output parameters, an algorithm for reducing the preparation time of the working fluid for the first launch of a propulsion system with an electric heating engine was built, the value of the start time was established by the modified first start algorithm with limited values of the power supply system.
