Results

The laboratory's three testing benches have been upgraded. They have been outfitted with modern high-vacuum oil-free equipment and specialized electric power supply and HFIE control systems, as well as ionic sources whose capacity ranges from 0.35 to 35 kW. The project team has developed and experimental state-of-the-art complex to research physical processes and test high-output ionic engines whose exhaustion rate amounts to 235 thousand horsepower. This is Russia's only testing bench equipped with an echo-free chamber designed to research and measure electromagnetic radiation of electric rocket engines. The project team has conducted an experimental investigation of the integral parameters of laboratory HFIE models and analyzed distribution of local parameters of plasma in the engine's exhaust stream.

Based on the theoretical and experimental research completed by the project team, the following engines have been developed:

• HFIE-45, designed for a transport and power supply module with a nuclear-powered propulsion system that is being developed in compliance with the Presidential industry modernization program in the spacecraft area;
• HFIE -16, designed for correction of orbits of geostationary telecommunications satellites.
The project team has developed the foundations of the technological processes required to manufacture critical HFIE elements using special alloys, composite and ceramic materials. Models of these elements have been tested as part of the small-sized laboratory HFIE models. The scientists have developed a complex of physical and mathematical models of the principal HFIE nodes, as well as the physical and technological foundations governing the development, design, and manufacture of HFIE.

The scientists have completed a ballistic analysis required to use high-output HFIE as part of transport energy modules to:

• Launch spacecraft to high-energy near-space orbits, as well as to planets and their satellites, including manned expeditions to Mars;
• Adjust the orbits of dangerous asteroids;
• Implement the "Reusable inter-orbital tow-vehicle" and "Reusable moon tow-vehicle" programs, etc.

The research results achieved by the laboratory have been used in the implementation of such important space projects as "Transport-energy module with a nuclear-power propulsion system", "Interhelio-probe", "Ballistic analysis of interplanetary flight schemes for Moon and Mars exploration", "Impact of electric rocket engines on the structural elements and onboard radio-systems", etc. These research and development projects have been implemented by the HFIE laboratory under contracts executed by and between the Moscow Aviation Institute and some of the leading "Roskosmos" enterprises, such as the Research Center named after M. V. Keldysh and Research and Production Association named after S. A. Lavochkin.

The laboratory employs a great number of young specialists represented by engineers, undergraduate and graduate students.
