Moscow, August 3 (Xinhua) — Specialists from the Moscow Aviation Institute (MAI) have developed an innovative HT-1000 engine based on the Hall effect with high thrust generated by a high-speed ion flow, the institute's press service reported.
The team from the Research Institute of Applied Mechanics and Electrodynamics (RIAME) of MAI worked on the creation of the innovative engine with the support of an industrial partner, the Orbitek company.
As noted, the principle of operation of the HT-1000 engine is based on the supply of electrical energy, which, under the influence of a strong magnetic field, ionizes an inert gas /for example, xenon or krypton/. This means that electrons are knocked out of the gas atoms, it turns into plasma, consisting of free ions and electrons, which generates the necessary driving force.
“The key element is the use of a magnetic field, which is created using an innovative magnetic engine system. It directs and holds the plasma, ensuring its stability and controllability. The electric field created in the ionization chamber accelerates the ions, ejecting them from the engine’s discharge chamber at high speed. It is this high-speed ion flow that forms the jet thrust that ensures the movement of the spacecraft,” said Alexander Bogaty, Deputy Director for Development of the Research Institute of PME MAI.
This development is suitable for spacecraft weighing 450 kg and more, operating in low Earth orbit with an active life of up to seven years. This type of engine, as the developers explained, is characterized by high thrust and fuel efficiency, can operate on various types of fuel, has a relatively small size and weight, as well as a high efficiency factor, can perform orbital microcorrections and maneuvers with great precision.
“These engines will not only ensure the functioning of satellites during their life cycle, but also perform orbital raising maneuvers, separation of devices during group launches, and deorbiting of devices at the end of their service life,” explained A. Bogaty.
In addition, the engine developed at MAI allows for a reduction in the volume of fuel reserves on board. This leads to a reduction in the launch mass of the apparatus, which reduces launch costs and increases the payload.
The development of the HT-1000 engine has now been completed, prototype tests have been successfully conducted, and preparations are underway for qualification tests that take into account specific customer requirements. Preparations for serial production are also underway. For this purpose, as reported by MAI, the Orbitek company in Zelenograd has created a high-tech production site with advanced equipment that meets the strict requirements of the space industry. –0–
