Nano-Maxx motors coming soon!

Check this out...Maximum Thrust of over 20 mN

You're gonna have one heck of a time getting an igniter in there....

Maybe 1000ga nichrome with igniterman conductive primer? I'm sure the ignition mechnaism is built in when the MEMS is fabbed. It would be interesting to know what the fuel was.

I found additional references to micro thrusters on r.m.r. now that I've had some time to poke around. Please excuse any line wrapping. Maybe this thread should have been in the Coffee House?

That's pretty good! Consider a MMX-1 has 200mN of thrust.

Way more efficient than BP, and it's reloadable!!!

A form of Hydrocarbon according to the website.

Now that is WAY Cool.. 20mN Wow!!! 2 sec burn. We'll never see the model again

If you think that MEMS thruster is neat, then check out the solid-state digital MEMS thruster developed for nanosats by Cal Tech, Aerospace and TRW for DARPA.

A wee bit technical in parts but lots of pictures.

Yeah I was looking at that one. Looks like there has been a ton of work on these for quite a while. The original link was just the first one I stumbled upon.

 

[bobkrech]

Yeah, the digital thruster has been around for a while. I came across it in May 2000 when writing a proposal on solar sailing.
