Condensable Propellant Hall Thrusters MTU Aerospace
The Institute for Space Systems' 100-kilowatt SX3 thruster operates on argon in a high-voltage mode using a LaB6 hollow cathode. Credit: University of Stuttgart.. Also in January, Busek began delivering its BHT-350 Hall thrusters for satellite constellations. In February, Busek's BHT-600 Hall thruster completed a 7198-h xenon duration.
Gen2 Starlink Satellites to Hit Orbit Powered by New Argon
Various thruster concepts based on vacuum arcs are currently under development, predominantly in the pulsed regime due to the power constraints on small spacecraft.. Hall-effect thrusters, among others. 49,50 It was not until the late 1990s that viable flight models of vacuum arc thrusters were being designed and built,.
Comparison of the efficiency data with other Argonfed Hall thrusters
Argon is a candidate as such a low-cost propellant, but it has never been used practically owing to its poor performance. We attempted two methods to improve the thruster performance: (1) by mixing xenon in argon propellant and (2) by modifying the thruster structure for the argon propellant.

propulsion system spread over seven Hall thrusters. The xenon feed system provides up to 2770 kg of xenon at launch and can be refuelable while in-orbit around the moon.2 The seven Hall Thrusters, in addition to 24 bipropellant chemical thrusters are designed to supply all propulsion needs for the entire lunar Gateway.
SpaceX on Twitter "Among other enhancements, V2 minis are equipped
The V2 Mini satellites also have new Hall effect thrusters that use argon, rather than krypton, as propellant. The thrusters produce 170 millinewtons of thrust using 4.2 kilowatts of power, the.
Talking SpaceX's new Argon Hall thrusters with Jonathan McDowell and
operating with argon and nitrogen propellant was also measured. This report presents the results of the follow-on test. II. Methodology There are many ways to break down the total efficiency of a Hall thruster into component quantities [22,23]. These components are determined by thruster telemetry, performance measurements, and
SpaceX just launched the first argonfueled Hall thrusters on Starlink
The V2 Minis will use argon-fueled Hall thrusters, a cheaper alternative to the xenon propellant that's typically used, according to SpaceX. The company says this marks the "first time ever that argon Hall thrusters [will be] operated in space..
Gen2 Starlink Satellites to Hit Orbit Powered by New Argon
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.
SubKilowatt Hall Thrusters โ Busek
The helicon Hall thruster is a two-stage thruster that was developed to investigate whether a radio frequency ionization stage can improve the overall efficiency of a Hall thruster operating at high thrust and low specific impulse. This paper describes an experiment that measured the single-stage and two-stage performance of the helicon Hall thruster operating at anode mass flow rates of xenon.
EP Part2 Working principle of Hall Effect Thruster & History of
Usage of argon in Hall thrusters has been readily demonstrated yet performance data in direct comparison to xenon is scarce [35]. Although stable operation was achieved, performance of argon as a propellant is poor compared to xenon and krypton. However, the recent use of argon in Starlink satellites was reported to have high efficiency.
Multiscale Modeling of Hall Thrusters
The argon Hall thrusters were developed by SpaceX engineers, the company said, and are the first of their kind to operate in space. The electric propulsion system is highly efficient, but low.
How Hall thrusters work (and why we can't simulate them) YouTube
Argon Scaling Nitrogen 1. Introduction In recent years the applications of satellites have rapidly increased. Be it micro to nano class satellites or precise formation flying low Earth orbit constellations, satellites are becoming a more federated system with single missions being carried out by several satellites [1].
Successful ionpowered rocket engine test could slash space missions to
We examine the use of argon in a Hall thruster. The thrust, the thrust to power ratio, the specific impulse, and the efficiency are presented for varying magnetic field, discharge voltage, and gas flow rates.
Talking SpaceX's new Argon Hall thrusters with Jonathan McDowell and
V2 satellites also feature new "argon Hall thrusters" โwhich are over two times more powerful than the earlier thrustersโto help them maneuver in orbit and dodge space junk. In addition, the.

The new argon hall thrusters provide the satellites with 2.4 times more thrust and 1.5 times the specific impulse than the previous thrusters. SpaceX also improved phased array antennas and E-Band interconnects so that each satellite can support four times the capacity of previous versions. Starlink Group 6-1 launch
Nasa and Aerojet develop experimental solar electric propulsion ion
Developed by SpaceX engineers, argon hall thrusters have 2.4x the thrust and 1.5x the specific impulse of our first gen thrusters. This will also be the firs.
