Hall Thruster - an overview | ScienceDirect Topics
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.
Review of alternative propellants in Hall thrusters - ScienceDirect
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.
Study on a hybrid-produced magnetic-field Hall thruster
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.
Performance of a low power Hall effect thruster with several …
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 ...
Performance enhancement of an argon-based propellant in a Hall …
2019年9月1日 · The Hall thruster was operated in a vacuum chamber whose diameter and length were both 1.0 m. The vacuum chamber was evacuated by a turbo molecular pump (3000 L/s) backed by a rotary pump (1500 L/min). The background pressure varied depending on the xenon mixture ratio and the backpressure increased gradually with the xenon fraction.
Experimental investigation of a water electrolysis Hall effect thruster
2022年4月1日 · We present thrust measurements of the Water ElecTrolysis Hall Effect Thruster (WET-HET) which has been specifically modified to operate on the products of water electrolysis. These results build on previous measurements of the WET-HET published by Schwertheim and Knoll [1], [2], with the same thruster and experimental set-up. What differs in ...
Thermal analysis of the Hall thruster in vacuum - ScienceDirect
2014年10月1日 · The temperature results of a Hall thruster for two types of heat flux distributions are compared with the measured results from a vacuum chamber experiment. For the oscillation of the plasma in the Hall thruster [13], [14], [15], the heat flux onto the wall would also couple with the oscillations and shall excite instabilities.
Deep space transportation enhanced by 20 kW-Class Hall Thrusters
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 ...
Characterization of a high-power Hall thruster operation in direct ...
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.
Discharge characteristics of Hall thruster with large height-radius ...
2021年8月1日 · A traditional Hall thruster generates a magnetic field to restrain electron movement through the use of electromagnetic coils [14, 15]. A large height-radius ratio enlarges the space between the inner and outer magnetic poles of the Hall thruster. For a fixed number of ampere turns of the coil, it reduces the magnetic field strength in the channel.
