6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory. In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters.
The SPS-40 Propulsion System, designed for satellites up to 1000 kg, and consists of ST-40 Hall-effect Thruster(s), Xenon storage and feed system, Power Processing Unit. The SPS-40 Propulsion System is designed for a power consumption of 300-500 W and can provide a total impulse of up to 350 kN∙s.
Hall effect devices produce a very low signal level and thus require amplification. The vacuum tube amplifier technology available in the first half of the 20th century was too large, expensive, and power-consuming for everyday Hall effect sensor applications, which were limited to laboratory instruments.
Busek's BHT-200 hall effect thruster. The first US Hall thruster flown in space, Busek's BHT-200, was launched aboard the Air Force Research Laboratory's (AFRL) TacSat-2 satellite. The Busek thruster was part of the Microsatellite Propulsion Integration (MPI) Experiment and was integrated on TacSat-2 under the direction of the DoD Space
Some devices that are used or proposed for use as thrusters are: Cold gas thruster; Electrohydrodynamic thruster, using ionized air (only for use in an atmosphere) Electrodeless plasma thruster, electric propulsion using ponderomotive force; Electrostatic ion thruster, using high-voltage electrodes; Hall effect thruster, a type of ion thruster
Aerojet qualified a 4.5-kW Hall effect thruster electric propulsion system based on technology licensed from the Busek Corporation. [6] [7] Aerojet is under contract to Lockheed Martin to provide the first two shipsets of the new thruster system for the next generation Advanced Extremely High Frequency (AEHF) system, a US Air Force program.
SPT-series thrusters. Upper-left one is SPT-100. SPT-100 is a Hall-effect ion thruster, part of the SPT-family of thrusters.SPT stands for Stationary Plasma Thruster.It creates a stream of electrically charged xenon ions accelerated by an electric field and confined by a magnetic field.
Psyche is the first interplanetary mission to use Hall-effect thrusters, although not the first to use electric thrusters in general. [ 42 ] The SPT-140 (SPT stands for Stationary Plasma Thruster ) is a production line commercial propulsion system [ 3 ] that was invented in the USSR by OKB Fakel and developed by NASA's Glenn Research Center ...
