Energy Absorbant Foam

Hi Tim,

Maybe you could try a protective foam material? Here is a link:

I found this material doing a search for Foam Materials on www.globalspec.com

Hope this helps,

Roger,

Thanks, I pulled up a list of manufacturers from globalspec - but there's a lot of them to chose from! Thank you for this one, I will check it out,

If it is solid state the shock of the crash will not be a problem the pro's use solid wire recorders and don't bother too much, fire is another matter. Your major problem will be from heat not shock.

Thank you, that was what I was thinking but was questioned extensively about impact resistance during my project presentation. I'm now thinking of using some sort of foam as a vibration absorber to protect the electronics in use and cite some articles on the survivability of solid state memory cards to show that impact resistance isn't really a factor. Thanks again for your advice,

Tim

Aircraft fitters use antvibration mounts that incorpoprate sprins and rubber mountings to absorb this sort of energy. I was in a past life an avionics fitter. I have recovered equipment from crashed planes and it usualy survives the crash so long as it does not burn.

Since the device is designed for use in ultralights, weight has to be considered. You could use 2 pound density PVC foam. It will isolate the device from shock, insulate it from heat, and will not combust. It comes as a two part liquid which is mixed and poured in place. As the name implies, it weighs 2 pounds per cubic foot. Hope this helps.

Don't forget to check for any changes in your C of G.
