俄研制出用于航天器的霍尔效应推进器

Core Viewpoint - The HT-1000 Hall effect thruster developed by a research institution under the Moscow Aviation Institute has completed its development and testing, offering a new propulsion technology for spacecraft [1][2]. Group 1: Technology and Functionality - The HT-1000 thruster generates thrust through high-speed ion flow, which can be used for trajectory correction of spacecraft [1]. - The working principle involves ionizing inert gases like xenon or krypton using the Hall effect, creating plasma composed of electrons and free ions, which are then accelerated and expelled to produce thrust [1]. - The thruster is suitable for spacecraft weighing at least 450 kilograms, operating in low Earth orbit, with an effective lifespan of up to 7 years [1]. Group 2: Advantages and Applications - The use of inert gas as a propellant reduces overall fuel storage and launch weight, enhancing payload capacity and lowering launch costs [2]. - The HT-1000 thruster can precisely adjust or elevate spacecraft trajectories, facilitate the deployment of multiple small satellites during a single launch, and ensure predictable operation of spacecraft [1][2]. Group 3: Production and Testing - The research unit is preparing for qualification testing of the HT-1000 thruster based on user requirements, with a production base established by the partner company "Orbital Technologies" for mass manufacturing [2].
