Review of electric rocket engines for small spacecraft propulsion systems

The article analyzes the current state of global development of low-energy plasma propulsion systems for guided small spacecraft. The aim of the research is to review the main types and constructions of electric rocket engines, to identify the problems arising in the development process affecting the energy and design features. One of the most demanded and promising directions in the field of propulsion for small spacecraft is ion engines. The use of electrical energy to create propulsion, as well as high-frequency electromagnetic radiation, allows minimizing power losses. A key advantage of plasma propulsion units is this utilization of energy in the propulsion creation process. The use of units of pneumohydraulic systems is the main way of supplying the operating body and their replacement by a wick infiltrated with organosilicon oil allows minimizing the mass of the propulsion system and increasing reliability.
