2014年8月26日 · The SPT Hall thruster, which is referred to as a one-stage thruster, uses a dielectric discharge chamber. In comparison, the TAL Hall thruster is a two-stage thruster and uses a metallic discharge chamber, which is divided into an ionization region and an acceleration region by an intermediate electrode.

2023年11月1日 · Hall thruster ignition and operation with adamantane was also demonstrated [123] with both thruster and cathode fueled by sublimated adamantane. Post experiment inspection of the cathode system showed significant carbon deposition within the system.

2024年7月1日 · Thus, the height-to-radius ratio of the thruster is 0.5. Existing 600 W Hall thruster data show that the rated discharge voltage is 300 V in most cases, the rated anode volume flow rate ranges from 20 to 25 sccm, and the channel cross-sectional area ranges from 1500 to 2000 mm 2. The latter two parameters are positively correlated.

2024年11月30日 · Through analytical tests on a thruster powered by a 5-kW source at 400 V, and 12.5 A current, computer simulations are conducted using an open-source HallThruster.jl developed using Julia language which gave 1D simulation of plasma properties of Hall effect thruster (HET), along a thrust of 0.687 N was achieved representing a three times ...

2021年1月1日 · The first experimental characterization of an SPT 2-type Hall thruster in direct-drive mode has been performed in 1997 [10]. In that test, the T-160, a 4.5 kW SPT Hall thruster developed by the Keldysh Research Center, was supplied by a 1 kW concentrator solar array testbed at NASA Lewis (now John H. Glenn) Research Center.

2023年5月1日 · It can be seen that in a traditional Hall thruster annulus, the surface area to volume ratio of the plasma, if assumed to be approximately toroidal, can be taken as, (12) A s u r f a c e V p l a s m a = 4 π 2 d h 2 π 2 d h 2 ∝ 1 h where A s u r f a c e is the plasma volumes surface area and V p l a s m a is the plasma volume. This is of ...

2020年6月1日 · The AEPS Hall Thruster, also known as HERMeS, has been originally developed in the framework of the activities related to the Asteroid Redirect Robotic Mission (ARRM) [20]. The second thruster, the 20 kW-class HT20k [21, 22], has been developed by SITAEL, starting from the experience gained from the development of a lower power thruster [23 ...

2020年10月15日 · The Hall effect thruster is an energy conversion device that uses electric and magnetic fields to convert electric energy into propellant kinetic energy (Arhipov et al., 2000, Zhurin et al., 1999). Compared with traditional chemical thrusters, the Hall thruster has the advantages of having a simple structure, a high specific impulse, and long life.

2020年2月1日 · The specific impulse of a Hall thruster is generally below 2000 s. According to the National Aeronautics and Space Administration (NASA), if the specific impulse can be increased to 3000 s or more, the adaptability of Hall thruster to space missions can be improved greatly [2]. Therefore, a high demand for high-specific-impulse Hall thruster ...

2023年2月1日 · With this premise, the EP sector is slowly adopting other fuel choices. For instance, SpaceX has massively invested in krypton-fuelled Hall thruster, using krypton for orbit keeping and partial orbit transfers in the Starlink mission, validating this technology in …
