Samudra,

 

Do the thrusters in your lab setup actually consume cathode material? How
are they affected by atmosphere compared with vacuum?

 

Seems like you should make a presentation to AMRAD on the PhoneSat bus!

Hi Amrad community. My GWU "microthruster" experiment for NASA has concluded
recently, with good results. Here is a video that shows the first firing of
a micro-cathode arc thruster subsystem that was eventually integrated with a
PhoneSat smartphone bus, at Ames Research Center last month. 

 

Some of you may remember I had started work on the microprocessor control
system in 2011 and 2012, and now all of that work has been rolled into a
complete subsystem where the triggers are generated by embedded software,
and result in actual thrust impulse-bits.

I'd be happy to hear from the experienced designers out there, the next
version of this system is going to have to be very small in form factor for
fitting in a cubesat.
