Current development status of the Hall thruster
« on: 02/20/2007 05:58 AM »

Hello

I am searching for informations about the state-of-art of the Hall thruster.
My last informations is that in 2005-2006, the GRC was testing the NASA-1000M, a 150 kW thruster. I know also that the NASA-400M was tested with krypton and reached Isp>4900 s, in 2005 I think.
My questions are :
- what is currently the most powerfull Hall thruster
  * available for commercial use ?
  * tested in lab ?
- the highest Isp ?
- is there a flight-proven Hall thruster optimized for using krypton, or even argon ?
- what are the last improvements of the life time, compared to the gridded ion thrusters ?
- if Hall thrusters reach the same range of Isp as gridded ion thrusters, will they become always more advantageous ? (better weight/thrust ratio ? better life time ?)
- what about the recent developments of Hall thrusters in Russia ?
- sending a 100 tons cargo to the moon with an array of high power Hall thrusters (100 kW each) and a solar power plant of 500kW - 1 MW, is it realistic by 2020 ?

I am interested in recent scientific articles, technical reports, etc., and also by studies of systems using Hall thrusters (probes,...).

Hi
Just a post to move this topic up...
No specialist around, about those nice Hall thrusters ?

Hi lambda0,

Hi !
Thank you for this link.
They say :
"You can really tailor the exhaust velocity to what you need from the ground"
It seems that is should be possible with this new design to vary the Isp, which is an interesting feature, but I think that it will be difficult to have more technical informations, as it is an experimental thruster, and the picture shows a classical Hall thruster.

Would it be possible to outfit SpaceShipOne or SpaceShipTwo with a Hall thruster or a VASIMR engine?

Or would the power requirements of such a system be too much mass to fit on SpaceShipOne or Two?
e^(pi*i) = -1

Electric propulsions are not adapted for this application.
Another thing is that they work in vacuum.

powerplant would be too heavy, thrust too low and, as mentionned, electric thrusters only work in a hard vacuum
