TL;DR: In this article, the main characteristics of the electrothermal arcjet thrusters in the process of the working fluid acceleration during the bench tests were investigated. But the main results of the study were limited to the acceleration of the thrusters.
Abstract: The subject of the research in this article is the measurement of the main characteristics of the electrothermal arcjet thrusters in the process of the working fluid acceleration during the bench tests. The purpose is to form a bench research facility to study the characteristics of the electric heating propulsion system for use in a space tugboat, taking into account the launch dynamics, operating conditions and shutdown dynamics. Tasks: measuring the thrust of the electric propulsion system as the main characteristic in the established and transient mode; determining the flow rate of the working fluid correlated with the thrust; measuring the parameters of electrical consumption ‒ currents, voltage, power in static and dynamic modes; measuring the external conditions of the simulating space environment, namely the vacuum, in the test chamber. The methods used are: tensometry, differential pressure gauge, four-probe measurement of power supplied to engine heaters, steam generator and tank of the electric heating system, ionization-thermocouple vacuum measurement. The following results have been obtained: the composition of the information and control system consisting of the tensometric sensor used with the electric heating propulsion system, flowmeter of the working body of the electric heating propulsion system, power meter of the heater, steam generator and the tank of the electric heating propulsion system, ionization-thermocouple sensors for vacuum determination. The software product for graduation of the tensometric sensor has been developed. The scientific innovation of the obtained results is as follows: the method of measuring the thrust of the electric heating propulsion system by means of tensometric sensor has been further developed, the method of measuring the flow of the working body of the electric heating propulsion system has been further developed, the method of measuring the power of the engine heater, steam generator, tank of the electric heating propulsion system has been further developed. For the first time an algorithm for graduation of the tensometric sensor for the electric heating propulsion system was developed and implemented in the software product.

TL;DR: In this article, the authors explored ways of reducing frozen flow losses via state-resolution numerical simulations (quasi 1-D, 2D, and 2D with swirl) to account for significant losses in thrust and efficiency of arcjet thrusters.
Abstract: : This research explores ways of reducing frozen flow losses via state- resolved numerical simulations (quasi 1-D, 2D, and 2D with swirl) Frozen flow losses in molecular vibration, rotation, and electronic excitation are believed to account for significant losses in thrust and efficiency of arcjet thrusters This report summarizes the accomplishments in the first two years of a four year research program designed to quantify frozen flow losses, and to generate design tools useful for the designer to enhance arcjet performance Frozen flow losses, Arcjets, Plasma thrusters, Numerical simulations, Supersonic reacting flows
