Scientists at the Moscow Aviation Institute (MAI) have announced the development of a revolutionary satellite engine capable of operating for an almost indefinite period.
This innovative propulsion system, designated HT-1000, utilizes the Hall effect. It stands out from existing counterparts due to its superior efficiency, cost-effectiveness, and a remarkably long operational lifespan.
The new thruster is designed for spacecraft weighing 450 kilograms or more, intended for operations in low Earth orbit with an active service life of up to seven years. Developers emphasize the engine`s considerable thrust, high fuel efficiency, compatibility with various propellants, as well as its compact dimensions, low mass, and impressive overall efficiency.
Alexander Bogaty, Deputy Director for Development at MAI`s Research Institute of Applied Mechanics and Electrodynamics, stated that Hall effect engines are indispensable for a range of space missions, including interplanetary travel, precise orbital maneuvers, and maintaining the synchronization of large satellite constellations.
Bogaty further explained that these engines will not only ensure the continuous functioning of satellites throughout their mission lifecycle but also enable crucial maneuvers such as orbit raising, accurate separation of spacecraft during cluster launches, and controlled de-orbiting at the end of their operational phase.
The core principle behind the engine`s operation involves generating reactive thrust through a high-velocity ion stream. This stream is created when an inert gas is ionized under the influence of a powerful magnetic field, leading to the ejection of electrons from gas atoms, forming plasma, which in turn generates the necessary propulsive force.
Currently, prototypes of the HT-1000 have successfully completed initial testing. Preparations are now actively underway for comprehensive qualification tests, followed by the commencement of serial production. To facilitate this, the company `Orbitek` has established a high-tech production facility in Zelenograd, equipped with state-of-the-art machinery that adheres to the strict standards of the aerospace industry.
